Frustrated

Worked fine for almost 3 years. About a month or so ago it stopped connected to the company server. Connects to my WiFi just fine. Using 2.4ghz router. Won’t connect to company’s Data or OTA server. Completely useless. Local HVAC installer says they have no idea why.

Barebones

Maybe it’s only the thermostat model I have, but I was expecting this to be much more than just a “set temperature” app. Where are the usage graphs? Fan speed/stage information over time? Temperature graphs over time, etc etc. These seem like basic features for a smart thermostat + app. Am I missing something?

Annoying

It’s super annoying when I change the temp on my app and then it doesn’t stick and I have to go back in 2 or 3 times to make it stick

HomeKit was promised, but not delivered

HomeKit was promised with a previous version to be on the roadmap and it’s never been delivered, what’s the status of HomeKit compatibility? I want to be able to ask Siri to set the temperature to what I want as well as the fan speed and humidifier.

Invalid code upon account creation

Updated review after response from the company. Despite codes being invalid when attempting to verify my email address, it looks like my email is now verified. Frustrating experience at first for the price of the system, but everything seems to be fine now.

App features are good and regularly updated. Satisfied customer after some initial hiccups.

HVAC good. App horrible.

Neither username or email recognized. Happened after an October update then again in December.

Developer just apologizes but doesn’t care. Which is why they do it repeatedly and get Apple to reset their rating stats.

Needs more options

You can not set or adjust a schedule from the app. Sometimes when you need it you find it unavailable.

Does not work

This thermostat as well as app doesn’t have a heat button. So when it is cold in the house there is no way you can heat up your house. Also, it goes off line very often, and I cannot regulate the temperature I want. I would not even put a star for this app as well as thermostat itself.

Won’t buy another

The app is terrible, when they upgrade the app , you lose your settings/login information. Overpriced HVAC equipment

Remember your Observer App?

I have one of your first apps for controlling the thermostat for the Comfortmaker. It is wonderful that you have moved on to bigger and better things. However, those of us still stuck with the app you haven’t bothered to update or upgrade in over 5 years would appreciate it if you would make the effort to actually get it to work.

Variable Speed optimization

I’m am so thrilled to have a system that is top notch and has a variable speed platform that allows for my home to practically be the same ambient temperature on all three levels. This unit rocks and I love the option of having the app that allows me to adjust the settings no matter where I am in the home or away from the home. I love it.
