Total Connect 2.0 Bug Affects WIFI Thermostats

We have learned that Version 5.8.5 of the Total Connect 2.0 Mobile App for iOS has a bug that affects WIFI thermostats. The update leaves users unable to control their WIFI thermostats with the mobile app. However, iOS users can still control their WIFI thermostats through the TC2 website.

Many users have found that upon updating to the latest version of Total Connect 2.0, they have been left unable to operate their WIFI thermostats through the app. This includes any Honeywell Lyric Round Thermostats and any WIFI thermostat that pairs with TC2 through a Total Connect Comfort, Honeywell Home or Redlink integration.

Please note that the bug only affects the iOS version of the Total Connect 2.0 Mobile App. Android users are not affected. Additionally, Z-Wave Thermostats are also unaffected. If you are currently running iOS Mobile App Version 5.8.5, then you can still use the TC2 website to control your WIFI thermostat. You should be able to access the website using the standard web browser on your iPhone or iPad.

We expect that Resideo will release an update to fix this bug in the near future. But it may take some time before this happens. Until then, Alarm Grid monitored customers should reach out to support@alarmgrid.com with any questions. Alarm Grid will provide an update when we learn that the bug has been fixed.
