Getting incorrect readings

[OriginalCREart]

Hi, I have flashed the Mi Thermometer with this repo https://github.com/atc1441/ATC_MiThermometer and this is the flashed bin file.

I grap an ESP32-wroom-32d board, I have used your Arduino sketch and upload it to the ESP. everything seems to work fine from scanning to identifying the Mi Thermometers, but the output of the reading are not correct, sample output sensor # 0 -> temperature: -92.16C ; humidity: 241.26% ; voltage: 60.427V ; battery charge: 179% ; RF power: -75dBm sensor # 1 -> temperature: -156.16C ; humidity: 233.62% ; voltage: 53.771V ; battery charge: 247% ; RF power: -86dBm sensor # 2 -> temperature: -156.16C ; humidity: 215.70% ; voltage: 39.435V ; battery charge: 191% ; RF power: -85dBm

Only the RF power seems correct! what I did wrong?

Maybe it is related to the same question here ATC_MiThermometer, but the thing that I got a correct reading from ESPHome and homeassistant on another device.

Hi,

this is strange... There are different encodings depending on the selected Mi Thermometer firmware, but I thought I fixed this already (as mentioned in the issue you are referring to at the end). Maybe there is a third variant I did not consider yet...

Can you please confirm that you installed the library from https://github.com/matthias-bs/ATC_MiThermometer (and not from https://github.com/matthias-bs/ESP32_ATC_MiThermometer_Library)?

If yes, could you please compile again with debugging enabled (by setting "Core Debug Level: Debug" in the Arduino IDE) and provide some output?

Did you already try the other example (ATC_MiThermometer_Client)?

Hi,

Yes I can confirm that I have used the library from https://github.com/matthias-bs/ATC_MiThermometer and not from https://github.com/matthias-bs/ESP32_ATC_MiThermometer_Library, see the attached screenshot (green one).

Regarding "ATC_MiThermometer_Client", here are the results I got, still the same :confused:

Sensor 0: A4:C1:38:XX:XX:XX -87.04°C 218.22% 40.459V 8% -43dBm

Sensor 1: A4:C1:38:XX:XX:XX -179.20°C 233.64% 53.003V 26% -90dBm

Sensor 2: A4:C1:38:XX:XX:XX -135.68°C 243.83% 62.731V 230% -84dBm

I think it is now fixed, I closed the Arduino IDE, and reopened it again, it shows updates notification, one of them was the library "ATC_MiThermometer" version 0.0.2 instead of 0.1.0 as seen in the screenshot.

After update:

Thanks you so much for your reply and your time. I hope this will help others too.

You are welcome!

Besides, I noticed that there is still a comment referring to the wrong repository... I will make a new release now. And to avoid confusion, I have asked to remove the old repository from the Arduino Library Registry.
