Shelly Plus 1PM: Show internal temperature

[GerdRuetten]

Hi all,

i flash a Shelly Plus 1PM with Tasmota 13.0.0

The shelly device has a internal temperature sensor (see: https://kb.shelly.cloud/knowledge-base/shelly-plus-1pm).

It is possible, to show the value from this sensor on the Tasmota main menu and publish this via mqtt?

Best regards

Gerd

It is analog on gpio 32, if configured as ADC Temp and with the right AdcParam settings for temperature, to match the hardware. Haven't tried to dig up what the NTC settings should be.

On the non-PM Shelly Plus 1 "AdcParam1 2,10000,10000,3350" is suggested to get a "sensible value", but still needs calibration.

Did you try what I suggested, instead of the default values? With those, I'm seeing values like "ANALOG":{"Temperature1":59.12} from a Shelly Plus 1PM, but I've not tried to work out how "correct" this is.

hello, I'm apparently blind 😂

With this I get a temperatur near 48-50 C

For ESP32-Devices i found this Solution

https://tasmota.github.io/docs/ESP32/#cpu-temperature-sensor

Not nessssary to change the GPIO-Template

Not really, that is such a bad "sensor" providing bogus values, that the "solution" is to keep it disabled.

OK, hmmmm ... Thanks!
