@Wayne-TP What the system needs is the ability to save a schedule as a named setup within the app.  So in the app you would set up a couple of schedules one for 'normal use' and a second one for 'vacation'.  So when they go away you set it to vacation, and when they come back you just reload the'normal use' schedule.  This would also work well if people go on holdiday in the winter as they would not want the heating to operate in the normal way while they are not in the property.

A similar system should be added to allow you to just select a 'scene' from a button/widget on your phone that would either run for XX hours or until the schedule does something different.

We are very surprised that even when the KE100 is switched off (for example a room is temporarily not used, because one of the kids is on vacation), it switches on automatically as soon a switchpoint in its daily program is met. (Our kid is still on vacation)

In our eyes, switching off, is what it means: switching off (with frost protection). As soon as the kid comes back, we would w-switch the valve on.

With current functionality, you also need to remove the smart control. This is not user friendly and makes no sense.

Why not include the option permanently, when switching off. Would solve a lot of things. 

 

For the rest, we are very happy with the KE100 functionality.

  @Gibus Try switching to Summer Mode, which by rights should be called Vacation or Away.  From the description it appears to do everything you need.

  @gordon861 Fair point, is a good walk around. Thanks!

The 'summer mode' workaround can be used in individual cases. But what if such events occur frequently? You can't automate this using Scenes or Smart Actions or through assistant (eg Google Home) - you can only choose to turn the thermostat off or set a specific temperature, which will be overridden by the schedule. When I leave the house for a few hours, I would like to have the option to turn off all thermostats (or lower the temperature) by pressing one button or saying sth to Google Assistant, and when I come back, return to the temperature according to the schedule. In other words, it would be useful to have the 'away from home' option (pause the schedule and set low temperature) which can be turned on/off using Scenes and/or assistant command.

  @adik0nda Totally agree.

I've only had these things 48hrs and have ordered more for my other radiators, but I do think the software needs some more 'options'.

What I would like to do is not run any schedules on the valves at all and instead control it all through Home Assistant but so far all I can do is use manual control in Home Assistant to make changes, which sort of defeats the objective if it.
