Can another device cause these errors? As you can see, there are various devices and a lot of wires in this box, it's a control box for my ventilation system. There are sensors, fans, SSRs, etc.
I use the A2 board to have access to control all the devices through the smart home. I read the fan RPM, control the speed with a 0-10V signal, communicate with other devices via RS485, control the heaters via SSR, and much more. Can some device interfere with the signal and cause me to get errors when connecting I2C sensors? Because when I connect the sensors to individual ESP32s, everything works without errors, but there is nothing connected to the ESP32s except the sensors, so there must be no errors.
But I don't know what the problem could be and how to look for it...
