Go to his store
Itās currently out of stockā¦ Current plan is, to have it available again mid of January.
Hello, I see a strange behaviour on my R2107. The pump for heating (āHeizkreis 1ā only) is running always together with the warm water pump. This leads to high temperature spikes going to the heater.
Do you know a method do deactivate heating when warm water is heated?
Thx!
Hi Nils,
yes, there is a possibility to achieve this. Problem on my side was the opposite (before I added a heat pump and a buffer), I found it annoying, that the bathroom did not heat up for half an hour after filling the bath with water for the childrenā¦ So I added an electic circuit to enable the pump even when water is heated, just to learn later, that it sould be possible to configure it 
Iām not an expert with Buderus Logamatic, but it seems, that for the heating circuit 2, this can be configured. At least, it is, what the service manual tells: https://www.intec-heizung.de/media/pdf/ec/3d/6d/Buderus-Logamatic-R2107-M-Serviceanleitung.pdf
But according to this forum thread, it also affects heating circuit 1: Warmwasservorrang ausschalten Buderugs Logamatic 2107M - HaustechnikDialog
It also seems, that thorugh the km271 protocol, there even is a setting for heating circuit 1: esphome_components/components/km271_wifi/km271_params.h at 9d74d117d01fa6e8576c2e30f0d812f270c2a6d8 Ā· the78mole/esphome_components Ā· GitHub
In the esphome km271ās yaml, this config schould be named config_ww_priority_mode: esphome_components/components/km271_wifi/km271_params.h at 9d74d117d01fa6e8576c2e30f0d812f270c2a6d8 Ā· the78mole/esphome_components Ā· GitHub
Hope this helps 
Regards,
Daniel
Seems you solved it 
Hi Daniel, thanks for your help! I had to pick up some HA skills, but with the esp update nearly all data is now available, including the āUmwƤlzpumpeā. So now i can see that the āUmwƤlzpumpeā is not running when heating warm water.

There are definitely enough on the waitlist. I only need some time to adjust some components (request from community) and do the orderā¦

Hi Guys,
Believe me, the wait will definitely be worth it!
I speak from experience - at least, as far as Daniels brilliant HW is concerned. 
On the HA/SW side, Iām still a bit of a newbie, hence the following:
Iād like to calibrate the ADC, as Daniel mentions in #68 & #87.
What Iām not understanding is exactly which YAML file I should edit.
Is this the right oneā¦
@Daniel: bin nach wie vor begeistert - danke vielmals fĆ¼r das tolle Projekt. 
Jim,
This looks like iobroker, right?
Usually you do this directly from within ESPhome Add-On and I donāt know the iobroker-ESPhome-Addon at all.
But I can say, that there should only be a single YAML file (except the secrets file). The one that shows in the screenshot looks like it is the right one.
Regards,
Daniel
Hi Daniel, thanks for the confirmation.
Actually not iobroker, I was just using VSCodeServer to examine the file (sorry for the confusion).
Frohes Fest und einen guten Rutsch!
Jim
Hi Jim,
OK, now I understand what you didā¦ Thatās cool. Didnāt know, that it is so easy to bring this up. Maybe Iāll also give it a try once I have some time leftā¦
Wish you also happy X-Mas and new year!
Regards,
Daniel
