Comments on OJ Microline® UWG4 for Android

★★★★☆ Joffre Roberts · Dec 16, 2025

App will not boot half the time and when it does, there is major latency. You press a screen icon and seven seconds later it reacts. Unable to effect any changes in the programming remotely. Can't even turn it off or switch modes, it refuses to accept any changes. UPDATE: Have worked with the app to control floor heaters now for three years and during that time most bugs have been fixed. It has proven to be one of our better lifestyle apps. Wish it worked with Alexa though....

★★★★★ Tom Reynolds · Dec 1, 2019

Very nice simple interface to my floor heating controller. Easy to set up. Works perfectly. I love that I can monitor and control my floor heat from anywhere. Easy to make sure the floor is warm before we get home.

★☆☆☆☆ Matthew Shapiro · May 23, 2021

App is suddenly showing my floor as set for 32 F and with an actual temp of 80 F. The latter is the correct set-point, confirmed by checking the stat. Changing the set point in the app also doesn't work anymore, the stat never updates. The app hasn't been updated in months, so this must be a server-side break. I've confirmed the stat is successfully hitting the OJT servers, so it's not some weird incorrectly-handled reachability issue either.

★☆☆☆☆ A Google user · Jan 18, 2018

1) you "cannot" power "off" the radiant floors just like the Honeywell Total Connect App. Really? 2) I tried to change the start/stop schedule times and changes are happening, but it seems a slow update response. I clicked on Save, exit the Microline App, re-started process, logging again, etc. and it seems to "slow" refres- Masri

Does not show any of my configured thermostats... App seems broken.
