Make sure you update firmware
Works great, once you update the firmware. Powered 3 bedroom 2 bath house no problem. Not sure what max run time is, only ran for 6 hours before main power was restored

Hub only works if you use the smart app
When my Hub wouldn't turn on, they said I would need the app to update the Pro3s' firmware. Not being smart-stuff inclined (and not trusting that the update wouldn't introduce more glitches), I declined and shipped the hub back and got a bare-bones refund for it. I'm keeping the Pro3s, which are doing fine. I suspect the Hub was designed for the Ultra and they figured they could get it to work for the older Pro3s by means of a firmware update. But nothing in this 3-part bundle's description indicates the Hub won't work right out of the box. It won't (in my experience).

Excellent I recommend it 100%
Very good, it lasts a lot for the load with several connected devices.
