Temperature way off

[johannesx75]

Hi there,

one of my 5 ns panels temperature reading is way of. It reports around 100 °C even though the room is about 20°C.
(No its not Fahrenheit ;)

Comparing the logs with my other panels, I can tell that the resistance_sensor is off.

The problematic panel reports:

[11:42:21][D][sensor:093]: 'resistance_sensor': Sending state 727.06940 Ω with 1 decimals of accuracy
[11:42:21][D][ntc:026]: 'Temperature' - Temperature: 98.5°C
[11:42:21][D][sensor:093]: 'Temperature': Sending state 98.54311 °C with 1 decimals of accuracy
[11:42:31][D][sensor:093]: 'ntc_source': Sending state 0.20050 V with 2 decimals of accuracy
[11:42:31][D][resistance:039]: 'resistance_sensor' - Resistance 724.5Ω

compared to another panel:

[11:44:37][D][sensor:093]: 'ntc_source': Sending state 1.69533 V with 2 decimals of accuracy
[11:44:37][D][resistance:039]: 'resistance_sensor' - Resistance 11832.8Ω
[11:44:37][D][sensor:093]: 'resistance_sensor': Sending state 11832.82227 Ω with 1 decimals of accuracy
[11:44:37][D][ntc:026]: 'Temperature' - Temperature: 21.3°C
[11:44:37][D][sensor:093]: 'Temperature': Sending state 21.26015 °C with 1 decimals of accuracy

I've checked the panels temperature, it does not feel any warmer than the other ones.

Any Idea what's wrong with it? Any way I can 'calibrate' the sensor?

Thanks
