ADAX WiFi 17+

I have three Adax heaters and cannot fault them. I bought them because they look great and because they can be controlled by Wi-fi. The app is okay. The UX is not bad but not highly intuitive. The jargon can be confusing and it’s not straight forward to program. It is not fully smart either. What would make this app really good is if it managed to work with Siri, not to mention Apple Home. Some information on what things mean and explain what the recommended temperatures should be are things that don’t take up much development and easy to implement on the next version. I felt that the new version’s gradient background effect was a bit ‘un-modern’ when compared to the look of the actual heaters but that probably boils down to personal preferences. I look forward to the next release.

The thermostat are great, also the app. I like the new feature which says how much electricity have you spent.
I would add the following features:
- Set Away mode automatically depending on the phone localisation. So if all the members of the house are away it changes automatically to away mode.
- Turn off the thermostat lights when sleep mode, as an option. The (temperature) lights are really annoying at night if the thermostat are in the bedrooms. At least it should be possible decrease these during the sleep mode.
- Connection with IFTTT would be also great.
- When you create a schedule, it isn’t shared in the rest of the devices, you have to create it individually. That’s really annoying if you want to create just one for all the devices, it should be able to see it in all the devices.

The app looks nice and has some good features, but the most basic of these, especially in terms of minimising the environmental impact, doesn’t work! The scheduling feature appears reasonably simple to setup and activate, after some fiddling at least, but randomly de-activates itself. This means you’re no longer working to a set-back schedule and the heater is burning through energy overnight working to keep the room at the normal set temperature! There’s no notification of this, so it occurs without you knowing unless you check the app every day and re-activate the schedule. If you have to do that, there isn’t much point in having an automated schedule feature! A real shame, as it was promising, but badly let down by poor software testing and quality control.
