Making Vaillant Boiler Smart

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 dependsā€¦

VR700 data
bai data
VR71 data

In full I have 489 entities.

For example some VR700 entities:
image

FYI: Iā€™m running ebusd as a docker image. And connect ebusd with HASSIO via MQTT.

Ok thank you so much.

I donā€™t have the VR71 so I should connect the ebus board directly to the VR700, I supposeā€¦

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 Ā· john30/ebusd Ā· GitHub to make HASSIO also writable - by default itā€™s read-only. See lines 118-122

Yes, I was also enable to manual heatup the boiler. Finally :slight_smile: 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 cliamte config due to all the changes from the past (ebusd and HomeAssistant)ā€¦ now it works again.
