Different items in your home use different amounts of power. My idea is to create an integration that will be able to look at one value of power usage and determine the component device usage based on the different combination of usage values (where devices are all on the same circuit).
Eg.
Device 1 uses 23W
Device 2 uses 67W
Device 3 uses 18W
Integration would be able to work out that Device 1 and 3 is on if it sees 41W.
Similarly Device 1 and 2 is on if it sees 90W being consumed.
Off course this would be for simple applications where the power usage for different devices are different. Also that they are on the same circuit.
In addition, where there are combination usage numbers that do not add up, the integration can signal a device issue.
This was inspired by PowerCalc integration that works out power usage values based on device ON time.
Anyone would be interested in this integration and offer help? My programming skills are pretty limited but can put in the work if pointed in the right direction.
