WeatherLinkLiveUDP

Weewx Driver for The WeatherLink Live (WLL). It implements a HTTP interface for getting current weather data and can support continuous requests as often as every 10 seconds. Also it collects a real-time 2.5 sec broadcast for wind speed and rain over UDP port 22222. More information on the Davis Intruments website: See Davis weatherlink-live-local-api

To see a live demo of this plugin in vist meteo-otterlo.nl, it features the Belchertown weewx skin from Pat O'Brien with a MQTT broker to display the 2.5 seconds wind and rain data.

Installation

  1. Download the driver
wget -O weatherlinkliveudp.zip https://github.com/grebleem/WeatherLinkLiveUDP/archive/master.zip
  1. Install the driver
sudo wee_extension --install weatherlinkliveudp.zip
  1. Set the station_type to WeatherLinkLiveUDP and modify the [WeatherLinkLiveUDP] stanza in weewx.conf.
[Station]

    # Set the type of station.
    station_type = WeatherLinkLiveUDP

If you have a separate wind transmitter, set up according to Davis Instruments recommendations: How do I setup the weather link live to use a separate wind transmitter. Where wll_ip = 1.2.3.4 is the ip address of the WLL. For logging extra senors just add the transition id to the stanza by adding extra_id = x, where x is the id. Just one sensor recording temperature and humidity is supported for now.

# The WLL can get dat from up to eight transmitters. If multiple transmitters e.g. extra ISS for wind, extra temp sensor, requires the lsid_iss
[WeatherLinkLiveUDP]
    wll_ip = 1.2.3.4
    poll_interval = 10              # number of seconds [minimal 10 sec.]
    driver = user.weatherlinkliveudp
  1. Restart WeeWX
sudo systemctl stop weewx
sudo systemctl start weewx

Note: The driver requires the Python requests library. To install it:

sudo apt-get update 
sudo apt-get install python-requests

or us pip
