Hi to everyone

I have several power measurement devices (like wall plugs… and sensors from fibaro or others) that I want to implement in one single device. Is that possible?

I was thinking on a virtual device that shows the data in Watt or kwH in real time. The logic behind it is that if the summary of all devices (like AC… dishwasher… etc. etc…which are all behind fibaro relais… or wall plugs) exceeds 3kw homey starts shutting down AC for example.

I tried several things but none gets me close to what I wanna do. Any help would be greatly appreciated.  
**EDIT: i used the SEARCH function but i wasn’t able to find anything which was useful to sort this out.**

Search for Youless or P1smart meter?

Or the App Power by the hour.

Have you tried the \< group \> app?  
That allows you to add the power devices toa group and show the sum of them.

Nope, haven’t tried “group” app until now. Didn’t even know the existence of that. I’ll check it out and get back to you soon. 😉

Worked flawlessly!  
Now that I’ve grouped the power consumption of all I have at home I can create a flow that turns off AC or other things to reduce power consumption once it reaches the threshold of 3kw.

Thank you for your help! 🙂
