I’m migrating away from Athom Homey and to Home Assistant which is by far a more powerful and customizable platform. However in Homey, it is possible to add software based estimated power metering on the devices that doesn’t have built in power metering.
For instance for Sonos zones, Everspring dimmers without metering, etc. you have two custom settings on the device:
Power usage when off: 0 Power usage when on: 140
In the example above, an Everspring wall plug dimmer have a led strip connected which uses 140 watts when brightness is 100%.
That makes it possible to get a much more detailed picture of the current power consumption for all smart devices. A very clever function.
Is there a similar possibility in Home Assistant?
