If you want this functionality, have a look at:

Honeywell CH/DHW via RF - evohome, sundial, hometronics, chronotherm

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 yo…
