This uses RF to eavesdrop honeywell-based CH/DHW traffic, including evohome, sundial, hometronics, etc. - it does not use MQTT, node-red, etc.
This is beta code. It almost certainly wont break anything, but you never know
NOTE: you will need a USB dongle, either a HGI80 or something running this firmware (~£30)
It uses a client library, evohome_rf (WIP) that listens to the RF traffic and maintain a data structure that HA can poll.
The long-term plan for this library is to replace your controller (possibly with enhancements such as, e.g. more zones).
There is a corresponding HA custom_component, evohome_cc, that will expose the following data:
- Thermostats (temperature, battery_level)
- TRVs (temperature, heat_demand, window_open, setpoint, battery_level)
- other stuff, with more to come
You will need to add the custom component in the usual way - eventually it will be added to HA as an official integration.
Note that the most reliable/up-to-date information will be on the two github.com repos, above.
