I have now connected the TCA9458A and all three SHT sensors to another ESP32-C3-SuperMini board. I've been watching the log for over an hour now and haven't gotten any errors. I didn't change the wires, I just used a different ESP board. So I think the problem is not in the wires.
But the DS18B20 remained connected to the Kincony A2 board and it still sends warnings in the logs. And it seems to me that a few weeks ago there were very few warnings, maybe a few warnings once an hour, and now there are much more, every minute or two.
The DS18B20 has a built-in 5-meter cable that is free of any breaks, such as the one shown in the picture.
Could there be a problem with the A2 board or are there any other devices connected to A2 that interfere with the normal operation of the SHT/DS18B20 sensors?
