• Yes, the HTU21D is a SHT2x clone or vice versa.
    Tomorrow I can check the module with a real sensor, but I already think it will work for me. There hasn't been any code change since I last tried it.

    Could you try the other methods? Especially the synchronous variants readTemperature and readHumidity. I'm a little surprised, as the CRC-check didn't show any errors.

    Which board do you use? I tested the module with a Pico.
