I've used the average sensor to determine the average of a few entities for a long period of time (a month). These entities update very regularly (~every 5 seconds) and after I configured the average sensors, Home Assistant has become very unresponsive. It seems like every time the entities update, the average sensor gets recalculated, pulling in data for ~100.000 changes per entity. Every time it does this, there is severe input lag in Home assistant. Even Zigbee devices have been reacting very poorly and were reacting fine after I disabled the sensors again.
Describe the solution you'd like
Make the calculation of the average sensors in a seperate, low priority thread if it isn't doing that already?
Add an option to change the update frequency for certain average sensors? I don't need the average sensor for data of a month to update every 5 seconds.
Describe alternatives you've considered
Implement this in my own way?
