6 Channel S0 Meter

This Case houses a ESP32 Development board so it can be used as a S0 power meter with 6 individual channels. I used the WEMOS Lolin32 Development board but other will likely fit (maybe with tiny modifications to the design). The Pull down resistors for the 6 GPIO inputs that I use are soldered beneath the board. (maybe overkill since you can enable internal pull ups in esp32 but better safe than sorry). the two screw wholes for the lid are m3 molten inserts (mine are 8mm deep but any depth will do). The ESP32 is running ESPHome and is sending its readings to Home Assistant. (will include the YAML to this Thing)

If you are going to use this one, please upload some pictures and share your findings.
