App no longer works

The app simply doesn’t work anymore. It won’t let me login to the app (I used to be able to). Although I can log in with no problem through the website, it tells me ‘credentials not found’ when trying to login to the app.

CaSA Support helpful

As of November 2019 this app wasn’t working with Apple’s most recent upgrade iOS 13 that is installed on my iPhone, but the CaSA staff was very helpful walking me through getting thermostat connected to my home network with an old iPhone & everything works now using app on my current phone.

Terrible app makes thermostats unusable

I have had these thermostats for several years. The software in them and on the app has been glitchy but manageable until recently. The past few months something has changed with the app where it was resetting my temperature randomly. No matter what I did I never knew what to expect - if it would all of a sudden reset to 55 in the middle of the winter or other random temps. I tried ungrouping my thermostats. I tried deleting all of my schedules. There were still hidden schedules i couldn’t see that were resetting my temp. I emailed them repeatedly and they said they’d look at it and to let them know if it happens again. It happens all the time. I kept emailing them and they never took it seriously or put time into it. Recently I have a litter of newborn foster pups. They need it WARM in that room. And the app would suddenly bump it down to 55 degrees. If I hadn’t noticed and manually turned it back up, it could have had a tragic ending. It would randomly bump up my living areas to 73. They said the technician fixed it. And then it happened again. They said they fixed it again. And then it happened again. They recommended I “lock” my temperature in until it’s resolved. Well two problems with that a) now I can’t adjust my temps per my schedule which is half the reason I got these and B) it won’t happen again as long as it’s locked so they can say it’s fixed. Again. I requested a refund because the thermostats are unusable. They said I had to do it 30 days after buying. I said your app still worked 30 days after buying. I didn’t hear back on that.

I am probably going to uninstall and replace with Mysa. They have very good reviews. So $600+ down the drain. This company doesn’t know how to do software development and they don’t know how to quality test their software and they don’t know how to serve their customers. STAY AWAY!! The thermostats are not usable with their disaster of an app. They will make your life uncomfortable at best and if you have any critical need to keep your rooms at a certain temperature it could be disastrous. Just don’t do it. Worst company ever.
