weeWX Hardware Guide

Driver status

The following table enumerates many of the weather stations that are known to work with weeWX. If your station is not in the table, check the pictures at the supported hardware page — it could be a variation of one of the supported models. You can also check the station comparison table — sometimes new models use the same communication protocols as older hardware.

The maturity column indicates the degree of confidence in the driver. For stations marked Tested, the station is routinely tested as part of the release process and should work as documented. For stations not marked at all, they are "known to work" using the indicated driver, but are not routinely tested. For stations marked Experimental, we are still working on the driver. There can be problems.

AcuRite

According to Acurite, the wind speed updates every 18 seconds. The wind direction updates every 30 seconds. Other sensors update every 60 seconds.

In fact, because of the message structure and the data logging design, these are the actual update frequencies:

AcuRite transmission periods
sensorperiod
Wind speed18 seconds
Outdoor temperature, outdoor humidity36 seconds
Wind direction, rain total36 seconds
Indoor temperature, pressure60 seconds
Indoor humidity12 minutes (only when in USB mode 3)

The station emits partial packets, which may confuse some online services.

The AcuRite stations do not record wind gusts.

Some consoles have a small internal logger. Data in the logger are erased when power is removed from the station.

The console has a sensor for inside humidity, but the values from that sensor are available only by reading from the console logger. Due to instability of the console firmware, the weeWX driver does not read the console logger.

USB Mode

Some AcuRite consoles have a setting called "USB Mode" that controls how data are saved and communicated:

AcuRite USB mode
Mode Show data
in display
Store data
in logger
Send data
over USB
1yesyes
2yes
3yesyesyes
4yesyes

If the AcuRite console has multiple USB modes, it must be set to USB mode 3 or 4 in order to work with the weeWX driver.

Communication via USB is disabled in modes 1 and 2. Mode 4 is more reliable than mode 3; mode 3 enables logging of data, mode 4 does not. When the console is logging it frequently causes USB communication problems.

The default mode is 2, so after a power failure one must use the console controls to change the mode before weeWX can resume data collection.

The 01025, 01035, 01036, 01525, and 02032 consoles have a USB mode setting.

The 02064 and 01536 consoles do not have a mode setting; these consoles are always in USB mode 4.

Configuring with wee_device

The wee_device utility cannot be used to configure AcuRite stations.

CC3000

The CC3000 data logger stores 2MB of records.

When the logger fills up, it stops recording.

When weeWX starts up it will attempt to download all records from the logger since the last record in the archive database.

The driver does not support hardware record generation.

The CC3000 data logger may be configured to return data in METRIC or ENGLISH units. These are then mapped to the weeWX unit groups METRICWX or US, respectively.

FineOffsetUSB

The station clock can only be set manually via buttons on the console, or (if the station supports it) by WWVB radio. The FineOffsetUSB driver ignores the station clock since it cannot be trusted.

The station reads data from the sensors every 48 seconds. The 30xx stations read UV data every 60 seconds.

The 10xx and 20xx stations can save up to 4080 historical readings. That is about 85 days of data with the default recording interval of 30 minutes, or about 14 days with a recording interval of 5 minutes. The 30xx stations can save up to 3264 historical readings.

When weeWX starts up it will attempt to download all records from the console since the last record in the archive database.

Polling mode and interval

When reading 'live' data, weeWX can read as fast as possible, or at a user-defined period. This is controlled by the option polling_mode in weewx.conf.

Polling modes for Fine Offset stations
Mode Configuration Notes
ADAPTIVE
[FineOffsetUSB]
    polling_mode = ADAPTIVE

In this mode, weeWX reads data from the station as often as possible, but at intervals that avoid communication between the console and the sensors. Nominally this results in reading data every 48 seconds.

PERIODIC
[FineOffsetUSB]
    polling_mode = PERIODIC
    polling_interval = 60

In this mode, weeWX reads data from the station every polling_interval seconds.

The console reads the sensors every 48 seconds (60 seconds for UV), so setting the polling_interval to a value less than 48 will result in duplicate readings.

Data format

The 10xx/20xx consoles have a data format that is different from the 30xx consoles. All of the consoles recognize wind, rain, temperature, and humidity from the same instrument clusters. However, some instrument clusters also include a luminosity sensor. Only the 30xx consoles recognize the luminosity and UV output from these sensors. As a consequence, the 30xx consoles also have a different data format.

Since weeWX cannot reliably determine the data format by communicating with the station, the data_format configuration option indicates the station type. Possible values are 1080 and 3080. Use 1080 for the 10xx and 20xx consoles. The default value is 1080.

For example, this would indicate that the station is a 30xx console:

[FineOffsetUSB]
    ...
    data_format = 3080

Action --set-interval

Set the archive interval. Fine Offset stations ship from the factory with an archive interval (read_period) of 30 minutes (1800 seconds). To change the station's interval to 5 minutes, do the following:

wee_device --set-interval=5

Action --history

Fine Offset stations store records in a circular buffer — once the buffer fills, the oldest records are replaced by newer records. The 1080 and 2080 consoles store up to 4080 records. The 3080 consoles store up to 3264 records. The data_count indicates how many records are in memory. The read_period indicates the number of minutes between records. wee_device can display these records in space-delimited, raw bytes, or dictionary format.

For example, to display the most recent 30 records from the console memory:

wee_device --history=30

Action --clear-memory

To clear the console memory:

wee_device --clear-memory

Action --check-usb

This command can test the quality of the USB connection between the computer and console. Poor quality USB cables, under-powered USB hubs, and other devices on the bus can interfere with communication.

To test the quality of the USB connection to the console:

wee_device --check-usb

Let the utility run for at least a few minutes, or possibly an hour or two. It is not unusual to see a few bad reads in an hour, but if you see many bad reads within a few minutes, consider replacing the USB cable, USB hub, or removing other devices from the bus.

TE923

Some station models will recognize up to 5 remote temperature/humidity sensor units. Use the hardware switch in each sensor unit to identify sensors. Use the sensor_map in weewx.conf to associate each sensor with a database field.

The station has either 208 or 3442 history records, depending on the model. That is just over a day (208 records) or about 23 days (3442 records) with an archive interval of 5 minutes.

The TE923 driver will read history records from the station when weeWX starts up, but it does not support hardware record generation.

Action --set-interval

TE923 stations ship from the factory with an archive interval of 1 hour (3600 seconds). To change the station's interval to 5 minutes (300 seconds), do the following:

wee_device --set-interval=300

Action --history

Use the --history action to display records from the logger in tabular or dictionary format.

For example, to display the most recent 30 records in dictionary format:

wee_device --history=30 --format=dict

Action --clear-memory

Use --clear-memory to erase all records from the logger memory.

The console version number is available only on consoles with firmware dates after about 2006.

Highlighted values can be modified using the various wee_device commands below.

Action --clear-memory

This command will clear the logger memory after asking for confirmation.

Action --set-interval

Use this command to change the archive interval of the internal logger. Valid intervals are 1, 5, 10, 15, 30, 60, or 120 minutes. However, if you are ftp'ing lots of files to a server, setting it to one minute may not give enough time to have them all uploaded before the next archive record is due. If this is the case, you should pick a longer archive interval, or trim the number of files you are using.

An archive interval of five minutes works well for the Vantage stations. Because of the large amount of onboard memory they carry, going to a larger interval does not have any real advantages.

Example: to change the archive interval to 10 minutes:

wee_device --set-interval=10

Action --set-altitude

Use this command to set the console's stored altitude. The altitude must be in feet. Example:

wee_device --set-altitude=700

Action --set-barometer

Use this command to calibrate the barometer in your Vantage weather station. To use it, you must have a known correct barometer reading for your altitude. In practice, you will either have to move your console to a known-correct station (perhaps a nearby airport) and perform the calibration there, or reduce the barometer reading to your altitude. Otherwise, specify the value zero and the station will pick a sensible value.

Action --set-bucket

Normally, this is set by Davis, but if you have replaced your bucket with a different kind, you might want to reconfigure. For example, to change to a 0.1 mm bucket (bucket code "2"), use the following:

wee_device --set-bucket=2

Action --set-rain-year-start

The Davis Vantage series allows the start of the rain year to be something other than 1 January. For example, to set it to 1 October:

wee_device --set-rain-year-start=10

Action --set-offset

The Davis instruments can correct sensor errors by adding an offset to their emitted values. This is particularly useful for Southern Hemisphere users. Davis fits the wind vane to the Integrated Sensor Suite (ISS) in a position optimized for Northern Hemisphere users, who face the solar panel to the south. Users south of the equator must orient the ISS's solar panel to the north to get maximal insolation, resulting in a 180° error in the wind direction. The solution is to add a 180° offset correction. You can do this with the following command:

wee_device --set-offset=windDir,180

Action --set-transmitter-type

If you have additional sensors for your Vantage station, you can configure them using your console. However, if you have a Davis Weather Envoy receiver, it will not have a console! As an alternative, wee_device can do this using the command --set-transmitter-type.

For example, to add an extra temperature sensor to channel 3, do the following:

wee_device --set-transmitter-type=3,1,2

This says to turn on channel 3, set its type to 1 ("Temperature only"), and have it show up in the database as extraTemp2. Here's another example, this time for a combined temperature / humidity sensor:

wee_device --set-transmitter-type=5,3,2,4

This will add the combined sensor to channel 5, set its type to 3 ("Temperature and humidity"), and it will show up in the database as extraTemp2 and extraHumid4.

The --help option will give you the code for each sensor type.

Action --set-dst

Use the command to tell your console whether or not daylight savings time is in effect, or to have it set automatically based on the time zone.

Action --set-tz-code

This command can be used to change the time zone. Consult the Vantage manual for the code that corresponds to your time zone.

You can set either the time zone code or the time zone offset, but not both.

For example, to set the time zone code to Central European Time (code 20):

wee_device --set-tz-code=20

Action --set-tz-offset

If you live in an odd time zone that is perhaps not covered by the "canned" Davis time zones, you can set the offset from UTC using this command.

You can set either the time zone code or the time zone offset, but not both.

For example, to set the time zone offset for Newfoundland Standard Time (UTC-03:30), use the following:

wee_device --set-tz-offset=-0330

Action --set-lamp

Use this command to turn the console lamp on or off.

Action --start

Use this command to start the logger. There are occasions when an out-of-the-box logger needs this command.

Action --stop

Use this command to stop the logger. I can't think of a good reason why you would need to do this, but the command is included for completeness.

Action --dump

Generally, weeWX downloads only new archive records from the on-board logger in the Vantage. However, occasionally the memory in the Vantage will get corrupted, making this impossible. See the troubleshooting section WeeWX generates HTML pages, but it does not update them. The fix involves clearing the memory but, unfortunately, this means you may lose any data which might have accumulated in the logger memory, but not yet downloaded. By using the --dump command before clearing the memory, you might be able to save these data. Stop weeWX first, then

wee_device --dump

This will dump all data archived in the Vantage memory directly to the database, without regard to whether or not they have been seen before. Because the command dumps all data, it may result in many duplicate primary key errors. These can be ignored.

Action --logger-summary FILE

This command is useful for debugging the console logger. It will scan the logger memory, recording the timestamp in each page and index slot to the file FILE.

Example:

wee_device --logger-summary=/var/tmp/summary.txt

WMR300

A single WMR300 console supports 1 wind, 1 rain, 1 UV, and up to 8 temperature/humidity sensors.

The WMR300 sensors send at different rates:

WMR300 transmission periods
sensorperiod
Wind2.5 to 3 seconds
T/H10 to 12 seconds
Rain20 to 24 seconds

The console contains the pressure sensor. The console reports pressure every 15 minutes.

The station emits partial packets, which may confuse some online services.

The rain counter has a limit of 400 inches (10160 mm). The counter does not wrap around; it must be reset when it hits the limit, otherwise additional rain data will not be recorded.

The logger stores about 50,000 records. When the logger fills up, it stops recording data.

When weeWX starts up it will attempt to download all records from the console since the last record in the archive database. This can take as much as couple of hours, depending on the number of records in the logger and the speed of the computer and disk.

The wee_device utility cannot be used to configure WMR300 stations.

WS23xx

The hardware interface is a serial port, but USB-serial converters can be used with computers that have no serial port. Beware that not every type of USB-serial converter will work. Converters based on ATEN UC-232A chipset are known to work.

The station does not record wind gust or wind gust direction.

The hardware calculates windchill and dewpoint.

Sensors can be connected to the console with a wire. If not wired, the sensors will communicate via a wireless interface. When connected by wire, some sensor data are transmitted every 8 seconds. With wireless, data are transmitted every 16 to 128 seconds, depending on wind speed and rain activity.

WS23xx transmission periods
sensorperiod
Wind 32 seconds when wind > 22.36 mph (wireless)
128 seconds when wind > 22.36 mph (wireless)
10 minutes (wireless after 5 failed attempts)
8 seconds (wired)
Temperature15 seconds
Humidity20 seconds
Pressure15 seconds

The station has 175 history records. That is just over 7 days of data with the factory default history recording interval of 60 minutes, or about 14 hours with a recording interval of 5 minutes.

When weeWX starts up it will attempt to download all records from the console since the last record in the archive database.

Configuring with wee_device

Invoking wee_device with the --help option

wee_device /home/weewx/weewx.conf --help

will produce something like this:

Action --set-interval

WS23xx stations ship from the factory with an archive interval of 60 minutes (3600 seconds). To change the station's interval to 5 minutes, do the following:

wee_device --set-interval=5

Warning!
Changing the archive interval will clear the station memory.

Action --history

WS23xx stations store records in a circular buffer — once the buffer fills, the oldest records are replaced by newer records. The console stores up to 175 records. The history number of records indicates how many records are in memory. The history interval indicates the number of minutes between records.

For example, to display the latest 30 records from the console memory:

wee_device --history=30

Action --clear-memory

To clear the console memory:

wee_device --clear-memory

WS28xx

WeeWX communicates with a USB transceiver, which communicates with the station console, which in turn communicates with the sensors. The transceiver and console must be paired and synchronized.

The sensors send data at different rates:

WS28xx transmission periods
sensorperiod
Wind17 seconds
T/H13 seconds
Rain19 seconds
Pressure15 seconds

The wind and rain sensors transmit to the temperature/humidity device, then the temperature/humidity device retransmits to the weather station console. Pressure is measured by a sensor in the console.

The station has 1797 history records. That is just over 6 days of data with an archive interval of 5 minutes.

When weeWX starts up it will attempt to download all records from the console since the last record in the archive database.

The WS28xx driver sets the station archive interval to 5 minutes.

The WS28xx driver does not support hardware archive record generation.

Pairing

The console and transceiver must be paired. Pairing ensures that your transceiver is talking to your console, not your neighbor's console. Pairing should only have to be done once, although you might have to pair again after power cycling the console, for example after you replace the batteries.

There are two ways to pair the console and the transceiver:

  1. The weeWX way. Be sure that weeWX is not running. Run the configuration utility, press and hold the [v] button on the console until you see 'PC' in the display, then release the button. If the console pairs with the transceiver, 'PC' will go away within a second or two.
    wee_device --pair
    
    Pairing transceiver with console...
    Press and hold the [v] key until "PC" appears (attempt 1 of 3)
    Transceiver is paired to console
  2. The HeavyWeather way. Follow the pairing instructions that came with the station. You will have to run HeavyWeather on a windows computer with the USB transceiver. After HeavyWeather indicates the devices are paired, put the USB transceiver in your weeWX computer and start weeWX. Do not power cycle the station console or you will have to start over.

If the console does not pair, you will see messages in the log such as this:

ws28xx: RFComm: message from console contains unknown device ID (id=165a resp=80 req=6)

Either approach to pairing may require multiple attempts.

Synchronizing

After pairing, the transceiver and console must be synchronized in order to communicate. Synchronization will happen automatically at the top of each hour, or you can force synchronization by pressing the [SET] button momentarily. Do not press and hold the [SET] button - that modifies the console alarms.

When the transceiver and console are synchronized, you will see lots of 'ws28xx: RFComm' messages in the log when debug=1. When the devices are not synchronized, you will see messages like this about every 10 minutes:

Nov  7 19:12:17 raspi weewx[2335]: ws28xx: MainThread: no contact with console

If you see this, or if you see an extended gap in the weather data in the weeWX plots, press momentarily the [SET] button, or wait until the top of the hour.

When the transceiver has not received new data for awhile, you will see messages like this in the log:

Nov  7 19:12:17 raspi weewx[2335]: ws28xx: MainThread: no new weather data

If you see 'no new weather data' messages with the 'no contact with console' messages, it simply means that the transceiver has not been able to synchronize with the console. If you see only the 'no new weather data' messages, then the sensors are not communicating with the console, or the console may be defective.

Alarms

When an alarm goes off, communication with the transceiver stops. The WS28xx driver clears all alarms in the station. It is better to create alarms in weeWX, and the weeWX alarms can do much more than the console alarms anyway.

Configuring with wee_device

Invoking wee_device with the --help option

wee_device /home/weewx/weewx.conf --help

will produce something like this:

WS28xx driver version 0.33

Mutating actions will request confirmation before proceeding.

Action --pair

The console and transceiver must be paired. This can be done either by using this command, or by running the program HeavyWeather on a Windows PC.

Be sure that weeWX is not running. Run the command:

wee_device --pair

Pairing transceiver with console...
Press and hold the [v] key until "PC" appears (attempt 1 of 3)
Transceiver is paired to console

Press and hold the [v] button on the console until you see 'PC' in the display, then release the button. If the console pairs with the transceiver, 'PC' will go away within a second or two.

If the console does not pair, you will see messages in the log such as this:

ws28xx: RFComm: message from console contains unknown device ID (id=165a resp=80 req=6)

Pairing may require multiple attempts.

After pairing, the transceiver and console must be synchronized in order to communicate. This should happen automatically.
