ATAG One thermostat

[xAPPO (Kevin Hawkins)]

I have two ATAG Q38SR boilers in cascade, they are inter-connected by the wired ATAG bus. ATAG UK have just told me that I can’t use openTherm in this configuration which is infuriating as I had previously been told I could. I bought them just a few weeks ago to use with my evoHome system via openTherm. I can use evoHome on this system only via on/off heat demand it seems. Does anyone have any more information re this? The UK rarely use openTherm

If I added an ATAG One (not zone) thermostat do you think this might work? I am really only after getting information from the thermostat, flow/return temps, status etc. My boilers are remote to the house and difficult to access so I can’t see their info displays or anything inside nor press any buttons, When they locked themselves out I only knew a few hours later because the house went cold !

Or alternatively anyone know of a ‘remote display extender’ for the ATAGs?

Did anyone else notice (lately) that the room temperature in HA is not shown in decimals anymore?

(I hope I can post this in this topic?)

How can I turn on the hot water heating? I use Atag One Integration in Home Assistant. Unfortunately, I can only control the space heating, not the hot water.

Just installed HA (switching from domoticz) and really like this integration. The ATAG One thermostat has a seperate hot water schedule. However, the thermostat nor the app has a way to quickly/easily override the schedule.
Would be great if the HA integration can do something.
