Hi all,
even if my Project might not be the greates ever seen, i still want to share my results.
What was done?
In short: You can control the heating AND the warm water with two cards + some statistics for nerds like myself :D. And yes, this is still work in Progress.
Plans: Add some more informations without occuping more space
Replace graphs with an actual flow picture of vaillant with realtime stats
What are the requirements?
In my case, i have a Vaillant ecoTEC Plus, an vr_71 and a VCR700. (But this should work with any other vaillant supported by ebusd)
ebusd adapter
ebusd home-assistant AddOn (Or stand alone ebusd, doesnt matter)
HACS
mini-graph-card
Mushroom Cards
MQTT Broker
And what was done?
First of all, i will not focus on ebusd or mqtt that much. Only regarding the important config changes i made there. So lets start.
- ebusd: The most important thig here is, to enable WRITE access for HomeAssistant. This is done by adding the filter-direction=r|u|^w to the start Parameters of ebusd
- MQTT: If you are using multiple users for MQTT, make sure the homeassistant user can WRITE into the ebusd topics
- After you did add the vaillant device over ebusd and mqtt (just follow the official documentation) and make the adaptions, its time to create the climate entities:
mqtt:

current_temperature_template: "{{ value_json.s5.value }}"
Note: Currently, the “day” or heating mode is the only working mode and i really recommend to use it (that means, but the heater into the day mode and make sure its not changing automatially, because that will be done by HA in the future). I didnt have time and effort to further debugg there but i leave my current state here, so maybe someone else cann digg deeper.
Update:
- Heat = Day → Working
- Off = Off → Working
- Auto = Changing between Day/Night based on the schedules you setup → Working
- Cool = Night → Working
- Switches
This is a switch to load the storage ONCE. (Called "SpeicherfĂĽllung)
- platform: template
switches:
speicher_fullen:

turn_off:

friendly_name: "Speicher fĂĽllen"

Notes about that: I’ve used a condition card, becauseif the boiler is actually heating automatically the water (based on the time plan, if set up) it should not be overwritten by the one time loading. The second graph is showing some solar details. this can be removed if no solar system is active.
currently I’m analyizing it.
