I would love to hear more about your setup and build. How are you using the heat, and what did you have to build to make use of it?

exactly, i use https://iotawatt.com/ to monitor at the breaker box. Integration works well with HA

I have the circuits for all my “dumb” appliances monitored by my homeassistant. Then HA sends notifications to my phone. And it doesn’t need to send 3.6GB to the internet to do it.
