### 3/5 — Inaccurate usage statistics

*2023-11-26, version 2.1.3*

I’m finding the usage stats on the app are nowhere near what my smart meter tells me. In other ways it’s great for instant control and pretty easy to use. But I recommend getting manufacturers radiator placement guidelines before installing. My electrician has placed a few under the windows which is not recommended by ATC and I can see why. Because they are constantly trying to reach temps and won’t hold it so keep boosting. This uses much more electricity than is necessary. Once the curtains are closed and tucked up they are instantly stable at temperature. My electrician wouldn’t accept this but I can see it for myself.

### 5/5 — Best heaters and App

*2023-11-15, version 2.1.3*

As a electrician and installer, using quality products and materials is essential, for a job to go smoothly.
ATC your iLife style heaters are top quality and easy to install, but this app that works with them, is the BEST app I’ve ever used. 
Instructions were clear and easy to follow, linking each individual heater was simple, and setting up schedules wasn’t difficult.
Very impressive and will be using this for future projects.
