I have installed 2 of these for our clients and now removed and replaced both of them.
Feedback from the client was that the application was clunky and poorly designed and that the connecting process was infuriating and took upwards of a dozen attempts. We swapped it for the UWG4-4999 and the customer was able to program it, set up all schedules and everything in 15 minutes between both units. This was a very capable client and he has had no issues with any other smart product we have installed for him.
