Which UPSs support this? I bought these from Amazon that can be integrated into Home Assistant for Energy Monitoring. I'd rather use a UPS for Energy Monitoring.
I would say a current meter on each heater would be much more accurate, with no calculations required.
As a bonus you can turn them on and off remotely too.
These are much cheaper and do the same job. Additionally, these can be flashed with ESPHome/Tuya.
You must have a gas dryer? I would LOVE for a plug and play 240v power monitor. But instead I am going to go this route. For about $110, you can monitor the two mains and then $10 for each circuit you would want to monitor additionally (up to 4 more, then have to add a board).
Does anyone recommend Sonoff S31? it is with the Energy Monitoring feature which is the main reason I bought it
