Accumulate "on-time" for lights

[robertsorensen]

I know it would be somewhat in conflict with the name of this integration but anyway .....

Brilliant Integration that I use for almost everything.
I thought it would be great if along with power & energy the integration also calculated how long a light bulb has been on to get a sense for when you should expect to change them and to get a sense on whether some of the LED bulbs are even close to meeting the claimed lifetime.
I would imagine it would be fairly easy to do for fixed (i.e on/off) lights and could almost be calculated in Home Assistant using total energy and the bulb Wattage rating - still having it as part of the integration would be great.
For dimmable lights it's obviously more difficult because an hour of full brightness taxes less than an hour at 50% brightness but perhaps on-time could be binned in say 10 bucket - like x hours at 0-10%; y hours at 11-20% etc.
Obviously there needs to be a feature to reset the accumulation when a bulb is replaced - something similar to how batteries can be "replaced" in Battery Notes

@robertsorensen Glad you like the integration.
It's a nice idea but as you already imagined it's in conflict with the core functionalities of the integration and not something I want to add. This integration is focused particularly on virtual power/energy sensors and provide helpful tools to create these.
Need to keep things maintainable long term. Also this is a rather big development, which would add a lot of extra code and also maintanance time.
