Is there a way to directly read out the data what it is producing and so forth the integration in home assistant has been down more then it worked, sometimes it’s a bug sometimes it can’t connect it’s always something why it doesn’t work.
Is there a way to read out the data from a serial connection or something?
Not sure if your application talks to HomeAssistant using MQTT, direct integrated database updates, or some other mechanism, but you should be able to interrogate the database using standard SQL queries.
Modifying your data sensors to output serial data is an option, but you could strike problems if other parts of your data collection are modified and you dont keep synch.
Search the forum for “grott”…that may give you some directions
