Hx™ Thermostat 4+

App made a BIG IMPROVEMENT in v. 3.0

This app has been drastically improved and I hope they continue to make more improvements. Just a couple of suggestions: 1. Please show some stats on how much of the time the furnace or AC is running. Match this up with outdoor temperatures and unit set temperatures so we can tell if changes in settings are more or less energy efficient. Take a look at the DTE Energy app for ideas on how to do this so we can see hour, day, week, month and year trends at a glance. 2. I see Alexa integration, but I do not know how to make Siri work with your app. Adding this capability or instructions for it would be very helpful. What command am I to use with Siri to change the temperature on the upstairs thermostat? 3. Please use both the Location and Room names when referring to the thermostat names in settings. I have 3 thermostats and they all just show up as Home instead of Home Upstairs 4. Please include the ability to set the Filter Change notification in the app and include the date that the filters were changed so you know when it was last changed. Allow the Notification to be by hours used or months elapsed. I like to change my filters every 6 months. 5. Please make sure to include troubleshooting steps and definitions of error codes. Keep up the good work!!

Developer Response ,

Thank you for your feedback. We’ve prioritized fixing the issues you reported. The logout issues have been fixed in the new app. It no longer requires passwords and should keep you logged in. We also changed the layout of schedules to make them easier to edit. Give it a try and let us know what you think.

Beware - this version does not work

This version of the app does not work. When I try to link it to my thermostat, the app gets stuck on the second screen and will not go to the next screen.
Hugely disappointing as the previous version of the app worked fine with no issues.

Developer Response ,

Hi - apologies for the issue getting linked to your thermostat. Could you please reach out via Submit Feedback in the app so that our devs can address this directly? We look forward to getting you up and running with the app.

Notifications not working; need better documentation

I have all notifications turned on in the app and also enabled in the IOS settings, but I get no notifications either for soft lockout or hard lockouts on the heat pump. Something is either broken, or I am missing something, which brings me to the second issue: the documentation. It is a bit weak. I would appreciate some appendix explaining what the various log messages mean. There are other issues, but I would hope others have commented on those.

Update.

If you have both a furnace and heat pump on this thermostat, there is no easy way to see which is running and for how long. I see requests here for these features from over three years ago, but still... nothing. I have to suspect there is a better manual for the dealers, but they don't want us to tinker. If so, then they should say as much and make a simple black box user interface for us lesser beings, the customers.
