Only had installed for 2 - 3 weeks. No issues to date. Seems to be doing what it should so for. Right now, only AC is being used and my deaf blind wife likes the access thru her smart phone.
Handy and perfect for checking and operating your furnace. The only problem I have is the geofence doesn't have a big enough radius to cover Mexico where I have my winter condo.
This product is so convenient for hot/cold days when you arenât home, forget to change the temp, or want to check on the house when you are out of town!
