- Issue of the topic:
I am controlling heating via openHAB rules.
I have sonoff basic (running tasmota) with actuator and temperature sensor connected to each radiator in separate rooms that communicates via MQTT with openHAB.
My problem is that sometimes the temperature becomes NULL in tasmota for unknown reason (faulty sensor, or contact issue?) and the regular MQTT message with the sensor data is sent with NULL towards openHAB, but openHAB does not update the item’s value to NULL in this case but leaves the last set value untouched. Therefore the system and the rule does not notices that something is wrong and treates the value as valid.
I was wondering if there is a possibility to configure OH to update number item to null value as well or could you have any suggestion how to bypass this issue?
Thank you in advance!
