You can do it from the UI, under devices
Ok, I have found this point at the UI.
But how I can distribute this sensor “Thermometer_Wohnzimmer” to the MQTT?
[edit] Ok, I have found my solution with mqtt_statestream
Hello,
I’m in the process of configuring my HA. I have installed the PV panels and I want to use the energy more efficiently. This means I want to control my gas boiler as well. I have also the Vaillant EcoTec Plus. I was looking for an ebus module with Ethernet or WiFi but I have not found one. What are you using? Do I need to build the WiFi module or there is a ready solution available?
Thanks for the advice.
Is the C6 working properly? Any advise before buying it?
I’ve a Saunier Duval Thema Condens
I can’t answer that. But if it’s using Ebus, there is a chance (you could check the ebusd project)
Hi, I have a Vaillant flexoTHERM exclusive with a VRC700 control panel.
Could you give me some info to start implementing it into Home Assistant?
I shared some details about my system in this topic and I need help to understand if I can connect my system and what I need:
Hi. yes thank you for your advertise…I just need a step further and know if i actually can integrate this boiler into HA.
If you can find it here: ebusd-configuration/ebusd-2.1.x/en/vaillant at master · john30/ebusd-configuration · GitHub then yes.
But the easiest way is to use autoconf. But for that you need the adapter 
I’m pretty sure you will receive data into HA with ebusd.eu
I am currently at the point, what to do with the data 
currently I’m analyizing it.

Hi, can you tell me more about the wiring process and the list of entity/data that you are able to collect?
I attached it directly to my VR71 as there the eBus connector was easily accessable. And just attached a short KNX cable to it to my v5 https://ebusd.eu/
The list of entities depends…
VR700 data
bai data
VR71 data
In full I have 489 entities.
For example some VR700 entities:
FYI: I’m running ebusd as a docker image. And connect ebusd with HASSIO via MQTT.
Ok thank you so much.
I don’t have the VR71 so I should connect the ebus board directly to the VR700, I suppose…
Do you have the possibility to change and control parameters or are they just reading?
You can adapt ebusd/contrib/etc/ebusd/mqtt-hassio.cfg at 029aa27676f87a6c5b58bfb3f8630788c1cd881d · john30/ebusd · GitHub to make HASSIO also writable - by default it’s read-only. See lines 118-122
Yes, I was also enable to manual heatup the boiler. Finally 
the other settings are changeable as well but iam not changing them regularly (iam not using thermostats nor outdoor sensors anymore. Just the delta between input and output)
I have updated my climate config due to all the changes from the past (ebusd and HomeAssistant)… now it works again.
Edit: Another update, ive moved all resources to github for easier updating them and added some missing informatioins
Hi dMopp,
Very interesting. I also have an Ecotec plus boiler and I want to do something similar. I do not have VCR700, just a dry contact relay that commands the bolier at 24V, controlled by HA (when any of the flloor heating valves request heat).
I want to connect the ebus adapter to get data (other nerd here ) but also to replace the 24V relay if possible. Do you know how CMD of the boiler is done via ebus? I think you command the VCR700 not the boiler directly through ebus.
I would also like to know how modulating capabillties can be controlled from ebusd.
Thanks
César
I am also still installing, so could be wrong, but I believe they are all (boiler, VCR and ebus-rpi) on the same 2 ebus wires. Also, boiler and VCR will ‘absorb’ whatever commands/changes you issue from HA, and vice-versa. I am assuming this because of what I read here Connected Vaillant to Home Assistant – Floris Romeijn , down in the comments of 23jan2021 he states
I can set the temperature from two places, with my Home Assistant or with the my thermostat (VRT350). Changes by HA is reflected on the display on my thermostat.
Hope this helps.
