Great app which keeps getting better, nice work! I would also like to see a graph for DHW temperature, it would help to understand DHW usage better. Also, is it possible to have two or three time periods with different temperatures for DHW, like for heating? The reason is because I want to heat up the water once per day to 65°C because of legionela, and prefer to do that during the night, but during the day I want the system just to heat up the water to 55°C, because of lower en. consumption.

Huge improvement over the old sensoAPP. Reserving a star until I've used it for a while, but first impressions are good. The old app was an absolute binfire. Landing page needs work. If a single smart thermostat's battery runs out the app becomes useless until that thermostat has been brought back online. Some global settings don't have a logical position in the navigation hierarchy, and you drill down through a specific room to get to overarching settings. No Google home integration yet.

Not very useful. The information given today is either nonsense or non-existent. My aroTherm ASHP is functioning really well, but this app really doesn't reflect that fact. Even when it does work, the data is hard to find or understand. A better app us out there Vaillant, you just need to get someone with actual skill to build it for you. as of September 25 the app improved in functionality BUT it takes at least a minute to open and respond to commands and randomly requires my log in by email

Potentially a good app, but definitely needs some work. The most annoying bug is the status page, which frequently fails to update certain data so that the information it shows is inconsistent. For example, it will show an operation mode of heating, but a power consumption by the heat pump of 8W (what it consumes when it's in standby). The home screen is odd too - it shows an orange bar for the heating when it is on, but the hot water stays green when it is heating.

Last update killed this app. Can no longer make changes to the schedule. It appears to change, then when opened again it is as before. Also needs login every time and takes 45-60 seconds to login. I have had my ASHP for 3 years so know how it works. I emailed support and reset the gateway. Better, but still got issues with time to login and disconnections. Something in the system or app is needing a fix.
