Great for Cabin

I have 2 zone unit at my cabin. After getting Starlink, I was able to install the smartlinks in both head units. Now I can monitor the temperature and turn on the AC or heat a few hours before I come up so it’s more comfortable when I arrive. Amazing!

Error Eal OC

Keep this error

scott called me from mr cool great customer service

i had issue i left a review they called me and helped fix it next day thanks Scott!

Difficult to use

Very trying to set up. It worked locally, then not remotely, asking to add devices when launching app which I’m pretty sure can’t be done remotely. Took dozens of tries to get working, forcing me to pry open Mr. Cool air handler door with a crowbar and reseating wifi thingy, which ruined my uwife’s phone ability to connect. Most frustrating was the offline error telling me my phone was not connected to the internet (it was). It’s working for now, we’ll see for how long. Well, it’s now disconnected (again). Apparently it doesn’t play nice with my eero switching from 2.4 GHz to 5 GHZ and disconnects.
