Since the time window is set to 10s the current derivative factor needs to be set to 10.
Okey thanks, unfortunately I’m still having wrong values. I continue using my factor, it works well.

Sounds very exciting. I’ll give it a try over the next few days.
The only question I have now is that I have some smart plugs for some devices and therefore know the exact consumption. Does it make sense to subtract these from the total consumption?
Hello, i really like the idea to measure the power a device uses like this.
Since i use Home Assistant Glow to measure the power consumption in my home, i don’t have the A values needed.
Is there another way to use this method for measuring devices that doesn’t need the current A or would it just not be reliable enough?
Try this energy_disaggregation_1p_watt.yaml · GitHub Keep in mind it’s completely untested. You need to have a power sensor in W and create a derivative sensor for it.
Wow, this is amazing work tronikos! Being a statistics nerd and having several channels where I measure the actual consumption, this is a great way to add measuring to a few more consumers! 
I’ve implemented this and it generally works flawlessly, but I do have a couple of issues that I was wondering if you could help me figure out solutions to?
-
My oven seems to have two steps in the heating, with step one being about 4A, and step two being about 8,5A. I set the automation so that it triggers on consumption between 4 and 13A, but the problem is that my water heater is on the same phase and uses 8A, so the water heater triggers the oven-automation.
Now, the water heater has its own current meter so I get its actual consumption, so I was thinking about creating a template sensor that substracts the water heaters consumption from the ovens consumption. This seems like the easiest way to solve the issue, or do you have any better ideas? -
My stove top has a very varying consumption, ranging between about 2 and 13,5A on two different phases for left and right half, so setting the automation to trigger on this range would mean it triggers on almost all consumption on those two phases. In the image below I tried stepping through the different power levels on the stove to map out what it consumes.
I was thinking if it would be worth a shot to try to split the automation into several smaller ones and try to exclude ranges that are included in other automations, and then sum these in a template sensor?
And once again, terrific job with this! It was very easy to follow your guide and get everything up and running, and I’m amazed at the knowledge required to piece all of this together and package it this well!
