Helps with Allergies

Helps with Allergies
This is a very nice thermostat. It's one of the best looking I've see and has some great features. For example, my wife has allergies and the integrated air quality indicator will run the fan automatically whenever it needs improving. When using a HEPA filter this does indeed help. Other features are pretty typical for smart thermostat such as energy saving auto-away, smart scheduling, a simple phone app, and Alexa integration. I have a split system and have given my two thermostats simple names so I can say "Alexa, make it 75 degrees upstairs" or "Alexa make it cooler downstairs". It works as expected.There are some things that could be improved. When Microsoft dropped Cortana the thermostat lost voice capabilities. Which means I can no longer speak to it directly. This is too bad because I liked telling it to read the morning news or giving me the forecast. It also cannot show the forecast from the screen. It can only show the current weather. This is a big oversight and I cannot figure out why this has not been addressed with a simple update. Also the Alexa integration can be a little buggy. Sometimes I have to remove the GLAS skill from the Alexa app, and then reload it to re-establish Alexa communications. I'm not sure who owns this problem but at least I know how to fix it whenever it happens.Is it worth the money? I guess that depends. There are certainly smarter thermostats out there with more features for less money. But when I shopped a year ago GLAS was the only one that could proactively improve air quality by measuring VOCs. And to be honest I really liked the clear screen. For my money it was worth it and I would buy it again.Some advice...if you are replacing an existing thermostat GLAS comes with a plastic cover than can be used to cover the hole left behind. But I think it's better to take the time and drywall the hole instead. It looks nicer without the cover plate and the bezel can be painted to blend into the wall like I've shown in the picture.

5.0 out of 5 stars Great, Beautiful Product!
Reviewed in the United States on October 4, 2020
Not only is this one of coolest looking devices on the planet, it works great. The Alexa integration was simple to add via "skills" and the voice commands are straight forward and simple. I have two of these for each AC unit (upstairs and down). The upstairs was straight forward because we had a C wire for continuous power. The downstairs unit required the C wire adapter, but was simple to install at the air handler control panel. The instruction manual is very detailed covering all possible AC unit configurations. Some negative reviews have stated things that simply are not true. They have decided to discontinue the manufacture of the model, but support and warranty will continue. In fact, I've had two updates pushed to my units in three days. As far as the app being slow, I'm not sure how fast it needs to open to merely change your temp. It has to contact JCI servers to load local weather...which may be a little sluggish because their servers may not be that robust. An "always on" mode would be nice, but reality is it would shorten the life of the OLED. If you don't want temperature inaccuracies, make sure you install the rubber seal on back to avoid possible drafts through the wall. The Alexa skill use to drop every day and you had to log back in. This may be due to JCI not allowing user accounts to remain logged in to their servers. As noted by another reviewer, JCI has resolved this issue and the Alexa skill works on demand and stays logged in now. Glas is the premiere smart thermostat on the market and makes other smart thermostats look antiquated. Maybe JCI will offer a new model in the future. Love it!
Update 2024: Glas has worked fine since I purchased them almost four years ago, however as many have stated, JC has discontinued the device and support. I was lucky and bought both mine directly from Duke Energy for $99. So, I have the coolest looking dumb thermostat on the planet now. Too bad they dropped this product.
