Power meter for the space power usage. Used to run Espurna but it is supported by ESPhome now. Since we needed to flash a fresh ESP8266 board anyway, we will try to use ESPHome.

Hardware

• ESP8266 (Lolin NodeMCU v3)
• pzem-004t (V2.0 printed on PCB) (aliexpress)

Todo

• Install sensor
• Install value storage software (InfluxDB on 10.208.11.31)
• Install graphing frontend (Grafa on https://metrics.nurd.space)
• Print a case because of live 230V AC on terminals
• Config ESPhome, possibly using this (V3) or this (V1). We have a V2 so we might be out of luck here. Basic config with OTA done and added to Jarvis.
• Fix home assistant bits
• Clean up old bits (MQTT and such, old topic: power/main/#)
