myVAILLANT integration

iway · June 26, 2023, 9:33am

Seems Cooling Mode with our heat pump breaks the integration…

iz3man · June 26, 2023, 11:39am

Great to see that there is an integration for the myVAILLANT app. I’m always a little cautious to install something that relies on internet and the goodwill of the vendor.

Are there some “LOCAL only” approaches which directly connect to the devices?

Locoblade · July 8, 2023, 9:40am

Not sure if @pdd is taking a break at the moment and I hope all is OK but sadly the Github has been quiet since early May despite quite a few reports of the integration failing to find any devices or entities, presumably due to one or two elements in the setup that the integration doesn’t know how to handle. Hopefully he picks it up again soon as I’ve really missed having HA heating integration since I moved our heating away from a third party controller onto Vaillant controls last year.

mwrman · July 11, 2023, 7:43am

There is a third party hardware adapter you can use - it’s wired to the ebus terminals. They’re made in batches so if you place an order it takes a few months to arrive. HA has an add-on that can link to it. It is a bit technically challenging but I now have live data coming from the heat pump and I can write to a few settings. ebus adapter link

CommanderROR · July 11, 2023, 1:21pm

The ebusd project is well known, but it is apparently quite difficult to make it do anything useful. I am still hoping Vaillant will open up to third party control more over time. Their declared goal with myVaillant was to eventually offer Smart Home integration after all. Currently though, even their own app hardly works

GrogSym · July 21, 2023, 10:39am

Greetings! Great integration, I have 35 entities available over 6 devices. I’m not however getting the energy information coming through (for heating or hot water). I have an Arotherm Plus, VR720 and VR921. Is there anything I can try to force more info in to HA do you think?

pdd · July 21, 2023, 7:15pm

There’s a new beta version that’s hopefully gonna fix the issue with cooling states for everyone. Been busy, and only just activated cooling in my own setup at home.

@GrogSym energy information may also be fixed. Remains to be seen if the values coming in from the API match what’s shown in the app.

boelle · July 22, 2023, 8:42am

i asked this on github, but can we control the circulation pump ? no sense in running that when heat is not produced

svb91 · July 24, 2023, 4:00pm

@pdd: I just have a short question regarding your integration. In all of your “Tested setups” there is at least one controller (sensoXXX). Is this necessary to run this integration or would it be enough to use the integration together with a sensoNET VR 921 which is connected to the boiler?
I just want to update the heating modes dynamically (holiday mode or if there house is empty to stop warm water etc.)

pdd · July 24, 2023, 5:07pm

@svb91 I don’t know, but I guess if your setup is supported by Vaillant it should work in the app and then probably in my integration.

@boelle I don’t have a circulation pump in my setup, so I don’t know if that could be implemented. Is there an action in the app to turn the pump on and off?

Jaybeam · July 29, 2023, 1:26pm

@pdd I live in Belgium where Saunier Duval is sold under it’s sub brand Bulex. As BilalHP I also have a MiSense Pro and a MiLink v3. Since a couple of days I was migrated to the Migo Link app.
Would it be possible to check if I can get support in your add-on? My login link is This
Thank you!

Greetings, Rudy.

pdd · July 30, 2023, 9:48pm

@Jaybeam I added a prerelease with experimental support, I have no way of testing it though. Bulex seems to be the only sub-brand that doesn’t have a login per country, so I made that field optional.

Jaybeam · July 31, 2023, 11:43am

@pdd Philipp, thank you for the swift reply and added integration of Bulex.

However, after installing the beta I get an error in home assistant when I want to add the integration.
The error is: “Config flow could not be loaded: 500 Internal Server Error Server got itself in trouble”

It doesn’t mather iff Install it manually or with HACS.
I have debug enabled for the logging but there I can’t find any error related to mypyllant in the log after the error occured. With version 3.2 reïnstalled I don’t get that error, but In the logs I do see errors consurning the login.

Would you like me to send you the log to see iff you can find something?

Greetings,
Rudy.

david.depedro · August 1, 2023, 6:20pm

Hi @pdd Philipp, thank you for the effort in creating this integration.

As some other users reported previously, and because I’ve not seen any reply, I wanted to check how to deal with the problem of the Hub being correctly connected, but showing 0 instances.
For troubleshooting, I’ve tried version 2.0 and 3.2, and I’m having the same issue. I’m using myVAILLANT app on the phone, and a few months ago I had the SensoApp (I think it was called that way!)

pdd · August 1, 2023, 9:45pm

@Jaybeam my bad, the config flow was broken. Please try again in the latest prerelease.

@david.depedro I would need some logs, with debug logging turned on. There’s a section on that in the readme. There’s no telling what the Vaillant API returns for different setups, unfortunately.

Jaybeam · August 2, 2023, 5:35am

@pdd Thanks Philipp for another update. I downloaded b1 and when trying to install using Saunier i get following error:

Jaybeam · August 2, 2023, 6:18pm

@pdd Philipp,

Installing with HACS didn’t work correctly > It never gave me the option to select Bulex.
So removed the HACS install and downloaded the files manualy from the Bulex repo.

Now I was able to install and select bulex when loading the integration.

Now that the intgrartion is running I get this error:

pdd · August 2, 2023, 10:28pm

@Jaybeam @david.depedro there’s a chance both of these issues are resolved in the latest prerelease.

david.depedro · August 3, 2023, 6:13pm

Hi @pdd unfortunately, I’m still experiencing the same issue. I have downloaded the latest version (v.0.4.0.2b) and it seems to be facing the same issue. I have taken some logs again in case this could help you to track where the error may be appearing:

If there is anything I can do to help you, please, let me know! I really believe this integration is a game-changer! Thanks again for your extraordinary support!
