I'm not entirely sure, I can't debug because I don't have a serial interface to it. The board just stops responding to MQTT commands. I do see a lot of "connecting to MQTT" debug messages over the network, so I assume it does have WiFi. I should try pinging and see if it disconnects.

There’s your first lesson: Always have a debug header with serial pins on your board. ;) It should be easy enough to solder some wires onto the ESP32’s serial port… although wait, how are you programming it?

It’s also good to have a couple of status LEDs and a power indicator on any custom board. Then you can add blink codes to indicate errors etc.

I programmed it once and then flash OTA, I couldn't add LEDs because they messed skfh fbe photodiode's readings.

Use osc instead
