I implemented option 2 (with original KM271) and ESP32.
I get the setting values in the dashboard (e.g. automatic operating mode, burner on/off), but all temperature values are marked with **"hu".**
So the communication seems to work in principle.
**But why am I not getting any readings?**
Does it take a long time to see values or is there a defect?
