      My DHT22 stopped working in RC2 as the reported temperature is 2000º , it was fine in RC1

      The PT100 continues to run fine.

      M308 S4 A"Chamber PT100" P"spi.cs0" Y" rtd-max31865" ; define temperature sensor number 4 as a PT100
      M308 S5 A"Chamber DHT22" P"spi.cs3" Y"dht22" ; define DHT22 temperature sensor
      M308 S6 A"Chamber Hum[%]" P"S5.1" Y"dhthumidity" A"Hum[%]" ; Attach DHT22 humidity sensor to secondary output of temperature sensor

        So just to add some more data into this issue, I actually got some apparently real readings from my DHT22 (it's around 20ºC in this office) even if briefly.
        I was doing a G32 Bed Levelling at the time.
        Could not replicate with another G32.

        And....while writing this I got another reading while the printer is idle:
