Hi *,
after 5 days without any problems ,... it is back: DEVICE_DISCONNECTED.
I really don't get it!
My last experiment:
- I will now replace all sensors (have 50x DS18b20 backup)
- I will replace my Arduino Mega
(- Activate watch dog timer for device reset // this should not be necessary)
If it fails, I will bring thermal death to all DS18b20 and go back to a PT1000 in bridge with amplifier solution.
br,
meis
