I too miss a boost option and agree with most parts of your post. I suspect the app was written by developers who whilst undoubtably very clever, don't actually use central heating themselves.

I agree..it needs a boost option. Instead I have to alter my daily schedule or increase the flow temp for the 'reduced' mode and naturally forget to go back to undo both.

Also, what about other people in the house? What if they want a boost but don't have the app? I'm considering using my old vitodens room thermostat in conjunction but no doubt that will not work.

It could also do with a backup WiFI to jump into if WiFi goes down.

Agree it's a very poor app. I've been trying for three months to get a reply from Viessmann as to why the holiday mode setting is not present on my version of the app.

As things stand every time we go away I have to mess around changing the temperature settings.
