They work well but not as quick to respond as you will find with Z-Wave, Zigbee, etc. Check out these threads incl one where I had weird issues with using Picos to control Bond fans:
It turns out Picos and the Bond Hub transmit on a similar frequency and can cause interference. I swapped my Picos with other remotes within house and problem solved.
If you have any more questions after going thru those 2 threads, you can PM me so as not to derail this thread.
