I'm not trying to track power use by using a smart plug that monitors usage. I'm trying to find out how long certain lights and fans and things are on. (that have smart switches that report back to Hubitat if they are on or off) Is there an easy way to do this?

[image] ryanrwalker: Is there an easy way to do this? Not necessarily what you'd call 'easy', but doable. In Rule Machine you'd setup some local variables, or perhaps use some Hub Variables. You can trigger a rule off a switch changing its state, and depending on the new state, add some ti…

I feel like I am almost there, I think I am missing some of your picture on the top. How do I grab the time of it turning on and off? Was there a rule above your picture of "set now to current date and time) rule? Right now my version of this was seeming to just add to a running total of time on…

There's more to it than what I showed above. That was just to illustrate a bit. I'm not going to solve this tonight. I was actually thinking it might be fun to write a small app to do this, for any number of switches, and show them in a little table. I may take that on tomorrow as a small projec…

Someone is planning on writing an app to monitor energy use and cost system-wide or per device. That would - or could - probably cover what you want as well Energy Tariff - similar to Modes Let them know you're interested - to encourage their effort :smiley:

See this post: @ryanrwalker [image] Lights Usage Table Custom Apps A user wanted an easy way to see how long a light was on cumulatively. To meet this need, and to illustrate some basics of table UI, check out this app:

This is really slick Bruce. I will be using it all the time. Thanks so much. :ok_hand:

Thank you, Bruce! Exactly what I was looking for!

Interesting. I'm tracking all this via influxdb/grafana. I log all switch statuses and have a dashboard I can go back and look at a certain timeframe how many hours something was on.

Is there a simple way to track how long something is turned on in a day?"
