GLAS by JCI 4+

I don't write many reviews. However, I really want to see this app fix some, what I consider, major issues.

I replaced a Nest Gen 3 that worked great with a Glas thermostat. I did it because Glas is flat out sexy.

My may issues, which may make me switch back, is:

#1 - The app takes FOREVER to open. By forever I mean 15-20 seconds easily. And I have an iPhone XS Max and 1 gig internet at home. So it's the app, not me. With my Nest I could open the app and access the temp in a few seconds. Glas app is annoying slow when opening.

#2 - It's 2019, where is the geofencing? With Nest I had a perimeter of X miles away from my home the Nest would know I was away and raised the thermostat temp so I was not wasting money on the AC. The app needs access to the phones GPS, so this is just a programming change for Glas.

#3 - The app has crashed several times. Not enough to make it unusable.

#4 - Not an app issue, and not a deal breaker, but a portal on the Glas website to manage options would be handy.

Coming from another smart thermostat this app is definitely behind the times. You get three comfort “temperature settings” and that’s it; Home, Away, and Sleep and they can’t repeat within the day. For example I used to have my sleep start at 9 pm and then start again at 2am in case someone had messed with the thermostat. I can’t do this with GLAS. I had a Wake temp setting which was warmer than Home for Winter use to get everyone out of bed. That’s gone. I also used to have a Weekend temp setting which was a few degrees warmer than my Home setting. I also can’t do that now. The app works but it’s a bit slower and clunkier than its competitors.

In the end this is a pretty piece of hardware lacking quality software and I’ll probably end up returning it.

I have noticed that I lose connection to my device. The app will either crash or when it does load I get a prompt that my GLAS is offline and I can not control it from afar. First time this happened a few hours later it worked. I now have not had connection for a full day. This is not good when I’m rarely home on business and I try to monitor my thermostat. My other home has a core and never had an issue. I hope they resolve this soon. It is a cool looking product but functionality is more important at the end of the day.
