I've just noticed that if heat is turned on via the wall thermostat that the app doesnt reflect it as being "On" (I'm pretty sure it did before.) And STILL : 1) Like others I've found (and so has my partner on a different handset) that a lot of times "Apply Boost" does nothing but show the spin icon and eventually time out, requiring a "force quit" and relaunch. 2) While the app now records APP activity in the log (for every APP user), it fails to record activity initiated from the thermostat!

Hi Ener, Thank you for your update. The issues you describe with lagging and force quit are usually handset related. In regard to your suggestion RE app data, thanks its been noted, we currently only log EMBER data and not the hardware input, but this may be possible in a future update. - Terry EMBER https://www.ephcontrols.co.uk/contact-us/

Used the app for a few years now, and I was happy enough, even if it was always buggy, but now it doesn't work half of the time. The Boost function is especially temperamental. I select Boost and it keeps loading, but have to close the app and retry a few times before the selection is successful, and then nothing happens and I have to get up and press the button on the boiler to get it to work.

Worst app. System does not update/save changes unless you force close the app and restart it. Reinstalling the app does not work. The 1 hour boost button option on the app is always set to 00:50. No matter what time. So the boost can be on for hours on end unless manually canceled. A major limitation with this system is not being able to schedule different temperatures. What's the point of having a schedule then? Only had this system for a few months but maybe time to cut my losses and switch.

Hi Angela, sorry to hear you are having issues. Its important EMBER is closed and not open in the background, this causes issues. The PS System (programmer) has a single target temp. Our TS (thermostat system) allows for scheduled temp changes. Our tech team can advise if you wish to contact. - Terry EMBER support www.ephcontrols.co.uk/contact-us/
