Re: I2C problem still exists?
Thanks for the answer. The problem of cable length in my case does not occur because everything is in one small housing. But I reduced the clock to 100kHz anyway. As for the FW of the sensors themselves, it is of course difficult to say anything. It's been working fine for 2 days now. What will happ...

Re: Humidity sensor installed outside
A humidity sensor measures the relative (!!!) humidity. The amount of water in air highly depends on the temperature. Higher temperature => air can hold more water.

Yes you are right. But I don't want to test the new FW on a 24/7 working device (bit necessary).
And I do not have a free ESP32 at the moment, because I noticed this error message on such a platform.
I will order on Shopee, but the delivery will probably take a month.
