Instructions on how to re-set old thermostats paired with a previous hub would have been handy, but otherwise easy to set up and use.

All good so far ( but only been using a couple of days)

Review
The first unit was faulty (no LED light showing) but once I had returned it and got a replacement the setup was extremely straightforward. Pairing it with our thermostats was really easy and I am finding it easier to programme them from the app than adjusting them directly with their buttons. We now have control over the heating in our house when we go away and can ensure that it is ready for us when we return.

Easy to set up. Had it working in 5 mins. Was a bit more difficult to connect to Apple home kit but got there in the end. No complaints
