Energy usage doesn’t work
On the whole ok but annoying when things change such as frost protection temperature changes
So disappointing 😞
New boiler, lots of promises and hype about the phone app. Has got better but loses info - history and glitches so all of a sudden it goes into holiday mode.
Holiday doesn’t work
Each time we set our house to holiday it broke and we could not turn it back on through the app
Recent updates have improved stability 11/25
I have been using this app for over a year now and am familiar with it. Recent updates have improved stability and it is a pleasure to use. Well done Navien developer team👏😀!
Smart App
As others have said the Smart app is very temperamental and typically requires the app to be fully closed and restarted. If buying again I would consider trying to find another form of smart controller as the Navien version is very poor
