An ebusd add-on

Third party integrations
252

@Lupo @soscomo I’m glad you got the addon working!

both writing values and reading values is defined by the ebusd config files. these are managed by john30 on GitHub. see the discussions link above ( john30/ebusd · Discussions · GitHub ) where the contents of these config files and thus which values are read and written is defined.

unfortunately the open specification of the ebus data “died” sometime around 2000-2010 and Manufacturers such as Vailant are only using proprietary messages on the ebus. However there’s a vibrant community trying to reverse engineer things…

253

Thanks, i know the config parameter to read and write, --mqttvar=filter-direction=r|u|^w, but do not work.
I had another instalatiin in a rpi with a usb to connect to vaillant with ebusd installed in the rpi, and i can write with ebusctl, but here with the addond i do not know how i can write with or without terminal command, or with mqtt explorer.
Sorry i am not a expert…
Is possible use ebusctl with this addon? In what direction?
Thanks

you can write via MQTT as per docs: 3.3. MQTT client · john30/ebusd Wiki · GitHub

Due to the subscription to the topic, ebusd also allows actively sending messages on the eBUS. This is supported by using a specific suffix to the topic:

  • /get: initiates an active refresh of a read message from the eBUS.
    When the message was read, ebusd sends the corresponding topic to MQTT.
  • /set: allows to send a write message to the eBUS (if the access level allows it, see above).
  • /list: publishes all messages known so far (according to access level, see above).

For /get and /set suffixes, the optional message payload can be used to transfer additional input data, e.g. the values to be set for a write message or the needed input for a read message, separated by semicolon.

Many thanks for the add-on and community support. Now I can observe my old heating system.
Did someome also control the waterheating? This would be helpful for a holyday mode.

glad this is working for you.

for write commands for your device checkout the configuration repository and discussion links above. GitHub - john30/ebusd-configuration: ebusd configuration files

How do you debug errors in thermostat templates?

Finally got my adapter v5 and found a way to get data from my Ochsner heatpump.
I can see some values in the log output of the addon:

Even the mosquitto log shows incoming data:

Unfortunately i can’t see the temperature values in Home-Assistant as entities. Does anybody has an idea why?
Also wondering what’s the strange topic “3jg9gYDzuynbIaLKLpZtoA”?

259

I have used the mqtt explorer to search the right variable for the different states/commands.

260

MQTT Explorer shows me a topic only for the temperatures:

ebusd/temperature/outside
{
     "group": {"value": 0},
     "value": {"value": 0},
     "type": {"value": "0d"},
     "unit": {"value": "02"},
     "maxs": {"value": 500},
     "mins": {"value": -500},
     "temperature": {"value": 13.6}}

So the _template.csv seems okay, because the naming looks good. This topic and its values are nowhere in HA, or I can’t find them. I have a device called buffer and heatpump. But the devices in mqtt (HA view of devices) are missing some entities or values. The only have five values and every topic in MQTT explorer shows seven values.
Is Home Assistant blocking to take a “device” called “temperature”?

261

I received my V5 adapter last week and trying to setup everything, but I’m a bit stuck at writing values.
Reading is no problem.
I’ve added write to the filter direction and changed the accesslevel to *.

At first I was using the default config files and I only to see the adaptiveheatcurve in the MQTT controls, but no temperatures. Now I’ve downloaded the CSV files and put them local and I see lot’s of r;w types by default, but I still have only 1 control for the adaptive curve and nothing for temperatures.

I would like to control my thermostaat from Home Assistant, but I don’t know where it’s going wrong now.
Any help would be appreciated.

Well, it seems I can control things when I send a mqtt message, but I thought I would just get some controls in mqtt to make things easier.

There is also going something funky on. When I setup the addon I get average outside temp and boiler desired temp for example. After restart Home Assistant those are gone. I have 177 sensor after a fresh install only a 144 after a reboot.
I’m not sure what’s going on and those are 2 important values for my automations.

263

My V5 adapter starts to work…now I get a lot of data in HA (Entity ebus), but how can I start my heat pump?

for example, there is an entity called sensor.ebusd5_21576_status_heatpump_status
but how can I create a switch ?

I got the VRC-720 working :slight_smile:

I installed HomeAssistant OS on a Raspberry4. When installing the eBUSd addon I get the following error:
Can’t install ghcr.io/lukasgrebe/ha-addon-ebusd-aarch64:23.2.1: 500 Server Error for http+docker://localhost/v1.42/images/create?tag=23.2.1&fromImage=ghcr.io%2Flukasgrebe%2Fha-addon-ebusd-aarch64&platform=linux%2Farm64: Internal Server Error (“manifest unknown”)

266

eBUSd Update from 23.2.0 to 23.2.1 > after click on install > failed to call service update/install. connection lost

Update function in the AddOn:

+1 same here

268

+1 few days ago
Made nothing, but ebusd upgraded well yesterday. And some new control entities were created.

269

Update to version 23.2.2 works fine

270

for me on version 23.2.2 still round button RUN… no show me run again and stop… But addon works

Hello,
I have the latest Ebus 5 module and connected it to our Vailland heating (ecoCOMPACT VSC 146/4-5 E VRC700/6). I’m having problems with the correct integration in Home Assistant (Home Assistant OS).
What is actually the difference between @eBUSd and eBUSd Edge during installation?
Is there a good guide?
