For a long time I wanted to make a project to measure electrical consumption, it is one of those useful projects any time ...
Little has made little improvements but I prefer to start with the basics, a simple connection
We will add:
- Measurements of temperature.
- Heating resistance control via Relay or PWM AC.
- Integrations with Wifimanager to facilitate configuration.
- OTA integrations for remote programming of esp8266.
