You didn't mention if there were any issues in the programming aspect of the Harmony 890 with all these devices. If there were issues, I don't know that waiting on another Harmony product will solve your problem. For that matter, the URC MX810 may not be suitable either if you are looking for a remote to control whole house applications. My suggestion would be a URC MX980 and MRF350's (based on 9 devices, you would need 2 RF receivers or 1 RF receiver with double-headed emitters).
