ATAG One

Does what it says. Only issues so far... 1 When switching from manual to automatic, the setting temperature doesn't change to that programmed, it instead waits until the next switching time. 2. When in automatic, I would like an 'advance' button to flick to the next programmed setpoint rather than having to manually increase the setpoint. First world problems...

Attempted to register account, won't let me as my address doesn't have a street name and won't let me past the address page. Very poor design. Otherwise very good but can't use away from home.

App has poor design, works slow and can't connect to the Atag One 90% of the time. Also instructions on how to get everything working are unbelievably poor.

I can't control the thermostaat with the app. USELESS app! Disappointing as this was partly the reason why we chose this CV ketel. Irritating!

Servers offline? Unacceptable for this kind of service

The thermostat is fantastic. The app needs some work. On my phone the current temperature and the target overlap, decreasing legibility. Information is empty. And there is no way to delete messages.

Device doesn't work (for me) with WEP security. WPA only, meaning I'm expected to compromise my entire wireless network for device to stay connected.

Keeps shutting down and won't reconnect to the server very disappointed.

Can't connect anymore to my One

Suddenly lost wifi connection... Endless trying to reconnect reconfigure... Solved by Port Triggering in router for ports 10.000 and 11.000 plus reboot router

Can't connect to the One server. Have to re-configure the WiFi every time before I can use the application on my phone. Just useless! Sort out the bugs before putting it on the market.!!

Endless retreing too connect without success. I'm using a Google nexus ... The manual is unclear, there are TWO network (WiFi connection). The Atag One you should use the very first time (and then never again). And your own network ...

This app makes a simple task very complicated. On manual mode I can't turn the heating off (only down to 4C), so my boiler pump runs constantly which interrupts my sleep. My battery life has halved since installing, my phone no longer makes it to lunch before needing to be charged.
