I’m trying to track the power usage each of my entities (lights, TVs, etc) are using while they are on. I figured this would fairly simple for HA but when I start looking at my light entities none of them show and off-on history though I know they have been on. The history of the entity has “No state history found” and “No logbook entries found”.
Look at the configuration / logs menu. Does it show database errors?
If so, you need to either repair or delete the recorder database. There are many, many posts on the forum sowing how to do this. Use the search function.
