Hello everybody,
even the Shelly H & T can be integrated with the original firmware in Homematic.
A flash of third-party firmware like Tasmota is not necessary.
This has the advantage that app and cloud compatibility are preserved.
This description is version 2 of this little prject.
# 1 Introduction and project presentation
Shelly H&T as a virtual device in Homematic
In addition to temperature and humidity, the battery voltage and battery status can also be displayed as an option.
Furthermore, a failure of the Shelly H & T can be detected and reported.
All App and Cloud Shelly properties are fully retained, regardless of use in Homematic.
Querying the information puts a strain on the battery and shortens its life cycle!
In order to save the battery as best as possible, my implementation recognizes when the Shelly H & T sends its data. And then the information for Homematic is retrieved. An additional awakening of the Shelly H & T does not take place.
The degree of extra battery load depends on the desired data accuracy and the resulting setting in the Shelly H & T.
I myself run all installed Shelly on a Homematic Charly with CCU3 firmware.
