Lightwave TRV Integration for HomeAssistant

This adds support for Thermostatic Radiator Valves (TRVs) to the LightwaveRF integration into HomeAssistant. This is for Series 1 Lightwave.

Getting Started

Lightwave does not provide an interface, via the API, to query the Lightwave Hub for the current TRV status. Instead the status is broadcast to the LAN. This proxy captures the TRV broadcast messages, and makes them available to a HomeAssistant polling loop.

Installing

• github

git clone https://github.com/ColinRobbins/Homeassistant-Lightwave-TRV.git

• pip

pip3 install lw-trv-proxy

Requirement

HomeAssistant 0.109 or greater

Configuration

See HomeAssistant/Lightwave

Run the proxy

The proxy is (by default) configured to run on the same server as HomeAssistant. No configuration should be needed. Simply run it...

lwproxy &

Command line options:

• -v verbose
• -i ip_address IP addres to run the proxy on. Default 127.0.0.1
• -p port Port to run the proxy on. Default 7878

Reboot

You will need to run this as a service to survive reboots etc. I've created a systemctl template service description in lwproxy.service.

Test

Restart hass. (A restart is required, simply re-reading config is not sufficient)
