Hello   I'm trying to configure Home Assistant through Viessmann's API. My plan is turn on the pump to domestic water heating mode approximately 1 hour before starting water heating according to the set schedule. During this time the stator will be heat if heat pomp was off more then 8 hours. However the entity "TURN ON CU401B_S Domestic hot water" change to the domestic hot water and heating mode (domestic hot water only is required).  Moreover there is another entity: "CU401B_S Heating" which only has two values: "OFF" and "AUTO". AUTO turn on the pomp to the domestic hot water and heating mode also.   Does IOBroker has same entities ? Or somebody could share his solution in Home Assistant ?   Thanks and Regards, Mirek ...

You are absolutely right ! Just looking for temporary solution while Viesmann do something or not. Maybe it's possible to create script in Home Assistant until Vicare will be updated.   Regards, Miros ... Mehr anzeigen

@Flo_Schneider  Hello Flo, Can you confirm that it is safe to turn on hot water on demand (how does LotharN do it) when the system is off (avoiding stator heating) ? Anyway, the Vicare allows such a possibility.   Thank you in advance Miros ... Mehr anzeigen

Hello I just installed the 200-s D.10 and I'm very disappointed because no one told me about the increased power consumption in standby mode before. In addition, I am surprised that such energy-consuming systems are still being designed these days. And Viesmann's ignorance that he does nothing about it. ... Mehr anzeigen
