I would like to be able to read the status of my evohome zones without connecting to the cloud. Similar to the possibilities which are now in HA.
Current Behavior
Currently the binding only connects to the web API.
Possible Solution
https://github.com/zxdavb/ramses_rf provides a library that might be able to do this relatively easy.
It can use the expensive hard to find HGI80, but also sub 10$ electronics if you solder (Arduino nano & CC1101), or some completed version on ebay for about 30$ (nanoCUL).
Context
I run a hybrid situation with both a Natural gas heater, and a small heat pump. EvoHome is connected to the natural gas heater. At the moment the heat pump is connected to a secondary thermostat in the living room. It is set slightly higher than evohome, so my gas heater only turns on when het heat pump does not have enough power (usually when the outside temperature is below 10C).
I have been thinking about removing the 2nd thermostat from the living room, and replacing it by a Relay which is controlled by openhab, using the evohome temperature readings. This has several advantages:
Removal of one living room thermostat
Equal temperature readings (my two thermostats give slightly different readings, this causes me to have to set the heat pump thermostat higher than I would like)
I can make the heat pump a bit smarter (change heat pump setpoint with evohome setpoint, respond to evohome away mode, etc)
I do however get semi regular evohome emails stating that it has reconnected. Somehow my cloud connection appears slightly unreliable for the evohome system. Because of that I would prefer to read out evohome status locally. I don't want the heat pump to stop working on a regular basis.

Your Environment
I run OpenHab 3 in docker on an unRaid server.
