TO REPRODUCE

Erased with flash_download_tool_3.8.5.exe. Flashed with esptool.py new-1 .

EXPECTED BEHAVIOUR

Lower working temperature.

ascillato commented 3 years ago

Hi, I have the same device and the temperature is normal. Seems to be hardware issue. You should ask for a replacement to your seller before it burns.

redguyz commented 3 years ago

Hi. Thanks for answering. Actually I use 3 identical modules. Previously they worked normally with ESP32 Cam Webserver. Now they are flashed with Tasmota. Two of them show high temperature. The third one is OK. Strangely, the mentioned two were firstly erased with ESP download tool. The good working one was flashed directly from ESP32 Cam Webserver to Tasmota. Simply coincidence?

Jason2866 commented 3 years ago

Please try latest version with PR #12936

redguyz commented 3 years ago

Unfortunately no change with 9.5.0.7. Web interface is a bit more responsive. The temperature is still very high. Currently the readings are around 90 deg C.

ascillato commented 3 years ago

Please, try to erase all flash and flash again

redguyz commented 3 years ago

Well, flashed the module after full erase. The result is not good. Still have readings around 90+ deg C...

ascillato commented 3 years ago

And if you touch it, it feels too hot or just warm?

redguyz commented 3 years ago

It feels hot. But not too much. Maybe around 40-50C. I don't believe the chip inside to be 90C. That's why I'm saying readings. Is it possible to be a program error for calculating the temperature? Or maybe another type / faulty thermal sensor?

Jason2866 commented 3 years ago

Temperatur is read via Arduino API from Tasmota. Nothing can be done if the values are off. No Tasmota error. Closing since the device is working as it should

Wolvverine commented 2 years ago

Have the same issue with temperature.

Geitde commented 2 years ago

It seems to be Fahrenheit.

The displayed 94°C, would, if that is Fahrenheit, be 34°C, which is ok and would look normal.

If I log in the temperature is rising to about 100°F, which resembles around 37°C. So I guess someone forgot to convert from Fahrenheit to degree.

sfromis commented 2 years ago

No, it is not about unit F vs C. That "ESP32 Temperature" is a useless number without a clear relationship to reality. Do not waste your time looking at that, but use SetSensor127 0 to get rid of it. If you want to check temperature, use a finger, or some actual thermometer.

On one ESP32-CAM, the "random" number is 40°C which would be 4.4°C if it was actually 40°F. Another device, same room, says 12.78 °C. No, it is not cold here....
