How dit you do this? Hardware choices?
I have been looking for a raspberry zerro for a long time to run it with, recently I was able to buy an rpi4 2gb and I installed it. here runs a python script which sends mqtt messages to hass?
if you want to know more i can provide you with the info you need.
you can always send me a pm.
Long time noting done at the working project. Now we have installed an airco Mitsibutshi SRC50ZS-W R32 with a SRK-50ZS-W inside unit. Because in the summer the hot air is going up we have decrease the humidity and temperature. Cool air if falling down in the house.
I’m a little bit curious to know if somebody have exchange the inside unit (SRK-50ZS-W) from a air heater into a water heater. Because in the winter we don’t use the airco, but we can use the heater inside the airco. But then we should have a water heater.
I have build in de OEG KWS-E with a direct script via USB to serial communication data by modbus. With a long power on-USB (5 meter to reach the OEG) Running a script from the configuration-file.
I can see the heat of the suncollecollectors, pump %, lower temper insite the house. The script is as follow:

Placed in the configuration-file and working!
