How to get ebusd active in home assistant

[jjtoard]

Hi I just activated the board and tried to link it to home assistant but without succes

I use the eBUS Adapter Shield v5

I linked the board on the ebus of the vaillant.
I changed the ebus config to rx/.tx pins. Is this OK ?
At least it states now ebusd connected but inactive
Should I do something with the delay / bitrate parameters ?

I have the feeling the ebusd doesn't see data on the bus.
Activated MQTT on ebusd but only get data for running/uptime/temp.rssi/signal but nothing else

How do I get the info active in home assistant ?

Ok found it !!!!!!

Ebus config on the board set back to the default value TCP so not tx/rx
In home assistant created the direcotry /config/ebusd and put there the file mqtt-hassio.cfg
Changed in the add-on

• the MQTT value to /config/ebusd/mqtt-hassio.cfg
• opened the unused optional configurations
  • changed the network adapter address to
    • ens::9999

After all this

• I could start the add-on
• I could see all the values being send via MQTT

So now looking to get all the values represented in Home Assistant.
I tought Home Assistant would recognize it as a new device but that doesn't look to be the case

I used MQTTExplorer on my Mac to see what comes. I then found the messages under Entities (and via Devices/MQTT) in HA. Also the MQTTExplorer helped me to identify messages and to write an automation like

trigger:
  - platform: mqtt
    topic: ebusd/hc1/DHWTemperature
condition: []
action:
  - if:
      - condition: template
        value_template: "{{trigger.payload_json._16_Temp10.value|float(0) > 0}} "
    then:
      - service: input_number.set_value
        metadata: {}
        data:
          value: "{{(trigger.payload_json._16_Temp10.value|float)}}"
        target:
          entity_id: input_number.valid_hot_water

Why so complicated? You could create MQTT number sensor:

# Example configuration.yaml entry
mqtt:
  - number:
      - name: valid_hot_water
         unique_id: valid_hot_water
         unit_of_measurement: "°C"
         state_topic: "ebusd/hc1/DHWTemperature"
         value_template: "{{ (value_json.[16].Temp10.value | float(0)) }}"
         command_topic: "ebusd/hc1/DHWTemperature/set"
         command_template: "{{ (value_json.[16].Temp10.value | float(0)) }}"

But if you use HA AutoDiscovery it should be populated in HA under MQTT integration.

I'm not an expert and that worked for me. Also a couple of MQTT entries are not showing up in HA, so I have to grab them via an automation.
Alas, thanks for the tip!

P.S. th reason for the automation was that the ebus reports invalid zero values which I'm filtering out this way.
