Its not clear what you’re referring to….
“My” CSV exposes write enabled parameters from ebusd, if you’re using a MQTT-hassio.cfg file that have the filter removed as per instructions you should be able to have writable entities in HA via native discovery.
You can try to create a custom/manual MQTT entity to test the write, the read topic is ebusd/……/entity
The write one is the same with appended a /set suffix.
You can also manually publish a MQTT message to the write topic and check if the write goes as planned
I succeeded. In the ebusd addon I added the writing line and now all the controls appeared except that I only have the Ariston Genus One boiler. I don’t have a hybrid system. Now I will have to find a way to not have so many entities. Thanks for the work done
Hello all,
i read all the thread, i’m the owner of ELCO AEROTOP MONO 11kw, heat pump, i tried with the web app\api integration and i am not satisfied with the data retreived.
i would like to integrate it via ebusd, and i think i understood what to do:
attach it to the “BUS” connector to the heat pump (the same where the heat pump contro panel is attached, and the same where the gateway for the app is connected) ex img:
enable via home assistant the ebus integration + the csv for the ariston heat pump
could anyone of you please confirm if i understood correctly? i am missing any step?
the hardware linked is enough, and need no raspberry or other part to work, right?
the BUS eletrical connection is safe? do i risk anything connecting the extra hardware to the heat pump BUS? there is no need for any extra wire?
thanks a lot for the help…
The whole process is described here and on the Github repo but you got the macro steps covered. The step you’re missing is configuring ebusd to talk to the adapter, this depends on how you’re running ebusd. If on native docker there is a config, if using the HAOS addon you need to look for info as I don’t use it.
If you’ll run ebusd on the same machine as HA (either as a separate docker or as an addon) then you won’t need any new HW
Yes, it is safe. The adapter you’re buying is octo isolated so the risk of interference with the bus is low, I’m using it since years without any issue.
I stress that even if it is a safe modification you are wiring something “external” on the proprietary bus. In case of any problem the first thing to do will be disconnect the adapter and see if the problem persists before calling the Ariston/Elco Service.
In some cases (in particular after an entire home power loss due to grid failures/cutoffs) my adapter needs to be rebooted because otherwise the bus goes into a loop of discovery that never ends, in this case my HP and Boiler did not work.
I think the problem is connected to the restarting sequence of the various elements, in my case is so sporadic that I have not invested time in diagnosis, when it happens I simply log into the adapter web gui and execute a reboot.
The adapter will need a solid USB-C power adapter and a couple of wires to connect to the bus port, if the length of wire from the adapter to the port is long you should evaluate the use of a shielded signal wire. I’m not an expert and I did not need it, the bus speed is rather low but the latency of the whole HA<–>bus communication must be as lower as possible.
