For total power monitoring, we used a cnct ddsu666 energy socket, then wired it up to read it using the rs485 protocol, and esphome sent it to HA. This device has been running for several years and is quite stable. They can monitor the voltage status in real time every second.

Each row is one report from a GitHub thread, an integration’s docs, or r/homeassistant. Check the date and the linked source before you buy.

In ReReHome

Once Home Assistant’s HomeKit Bridge shares it, this device reaches Apple Home as a HomeKit accessory behind your Home Assistant bridge, so ReReHome shows and controls it like any other.
