  • Ok, did some testing, and can confirm @Linyx's findings with the DHT22:

    • MDBT42Q module (2v04) - works flawlessly
    • ESP8266 - I have one that's been running for months without issue
    • ESP32 (tested with 2v01 and 2v04) - doesn't work.

    Checked the communication with a logic analyzer, and the DHT22 sends the right response (temperature and humidity valid, checksum ok). It's just the ESP32 can't pick up the response properly.

    Anybody any idea?
