Usage data not useful

I wanted to use the app to monitor gas usage but the app or the data supplied by the boiler is corrupt. Hot water & heat volumes are no where near actual. I have contacted NTI about these issues with promises of help which has never shown up via email. Our local installation group has been of no help with the online aspects of NTI products. Would not recommend at this point,

Not showing errors

My boiler stopped working due to Staus Lockout 603 (APS open) and needed to be reset to run again.
I had no notification, alerts or anything showing a problem in the app.

Nice to have

I really enjoy the abilities I have access to on the app. I would like if my thermostats could be adjusted from the app but I know it’s not easy to implement. Love being able to track usage

Poor App Execution

Recently got an NTI TFTN boiler and am impressed with it but very disappointed in the app. First off, it crashes on startup quite often. The interface is super dated and doesn’t at all align with the interface on the boiler or give me nearly the amount of insight or control. Why not just replicate the boiler touchscreen interface on the app? I’d like to see the boiler dashboard on the app and all the various drill down menus. Instead the app (when it opens) shows me a home screen that has nothing to do with my system and doesn’t display all my zones. It’s junk.

Latest version messes up cost calculations

I just downloaded the latest version and have discovered that the app no longer calculates cost properly. The previous version to this calculated cost properly so it would be best if you reviewed the changes to find out why it no longer works properly
