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 visit pc-wetterstation.de/weewx, it features also the Belchertown weewx skin from Pat O'Brien

https://www.pc-wetterstation.de/wetter/weewx/belchertown/index.html .

Installation

Download the driver
Install the driver

sudo wee_extension --install weatherlinkliveudp.zip

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] (https://support.davisinstruments.com/article/88ogxjf2mm-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 e.g. extra_id = x, where x is the id.

# Supports now a second ISS or VUE (txid_iss2 = x) with this values:
