photodiode

I mounted the #homeassistant #glow temporarily with some tape. I want to test it before building a box for it.
I didn't need to mess with the #photodiode trimmer, it did match already very well the electric #counter pulses.
The #esp32 struggled a lot to get wifi signal, we are very far from the access point, with multiple angled stone wall between. It's a miracle it could connect at all! I'll probably mod the #mcu to solder an external, bigger #wifi antenna.

This is it, assembled. The #rgb led should blink blue in case of network error and red when a pulse is detected from the #electricity meter. I already added it to #homeassistant (with the #esphome integration), so now it's just matter of trying it with the counter. I will probably need to adjust the #photodiode sensitivity to avoid false positives.
