Just as a note you can also get the same no -relay plug with Tasmota. This will give you a web interface on the plug itself and ability to change options (like power calibration) within Tasmota on the fly and can be brought into HE with the Tasmota sync drivers
The reason I mention this is if I am not mistaken ESPhome does not offer a web interface on the device and changing any settings in the device requires it to be reflashed.
