EAF Temperature reading not stable

szg

I recently purchase EAF 5V on Dec 2021. After few sessions I found temperature reading does not stable for multiple times. I have another digital thermometer in my obs for reference.

Thermistor plugin securely.
Firmware 3.2.3 and re-update to 3.2.3, problem still there.

Any recommendation? Or I got faulty unit?

If you can provide 2 completely different thermostats agree on what the temperature is in your house, and the EAF is wildly inaccurate in ASIStudio, then EAF Temp sensor is bad.
