myVAILLANT integration

[ynnor666 (Ronny)]

i also switched from myVaillant to vaillantCloud, works as it should. Do you get any Energy Values ? I only get The Current Power from the aerotherm plus 105 and from the hydraulic station but not other values from energy harvested, consumed and so on (this values were there after the install of the other integration, but then they were not available anymore in the vailant cloud.
Also the app from vaillat is not really nice, there are often no energy values displayed and the app is really less on functions.

How did you setup the timings for the integration ?

Thanks,
Ronny

@pdd Hi Philipp, maybe you are interested to open the original project so that there is a collaboration at myVaillant instead of that there are forks of your project which are further developed by the community?

Hi,

yes, I do.

The 0s are ok, as cooling is currently disabled.

This is my setup:

[ynnor666 (Ronny)]

Hi @romal many thanks,

i have the values slightly the other way arround, so i try your values, perhaps they work better.

Hey,

I have an automation that turns in the ventilation boost based on the difference between outside and inside temperature to cool the home (sort of).

However, the boost is only active for 30 minutes and then gets turned off. The logbook does not indicate what is turning off the boost. That results in the boost turned on every 60 minutes when the automation triggers and all conditions are met.

Does someone else has the Problemen and knows why?

Hello, after 5 days of using ´Seconds between energy data updates´ set to 900 secs I hit quota exceed error.
It’s documented - no complains.

What surprising me is, that reloading integration updates energy sensors regardless the quota limits. is it read from different, not limited endpoint?

Another question: is this component actively maintained? lot of issues are reported months ago without the component’s developer reaction.

Dear Philipp!
Love your Integration!
But since the Home Assistant Core Update the “Consumed Electric Energy” sensores lost it. I had them in my Energy-Lovelace but now they make no more sense… Can you please update the Integration?
Best regards Veronika

This issue has been already reported to the GitHub. Electrical Energy Consumption reported as 0 value on ECOTec Plus gas Boiler · Issue #338 · signalkraft/mypyllant-component · GitHub

I had to add it as a Custom Repository in HACS for it to work (today 31/07) as it wasn’t showing up in HACS for me either.
Specifically I added the GitHub repo URL with type “Integration”.

[psfshr (Paul Fisher)]

Does anyone know the status of the myVaillant integration? Its last update looks to have been back in May, and that seems to have been the last update for any of @pdd repos?

Wondering whether VaillantCloud may have a better option going forward, but also note that @romal seems to be the only contributor (so far).

Got my gateway installed just yesterday, so want to try and end up one way or the other now before I collect too much historical data

[ynnor666 (Ronny)]

I am on the (newer) vaillant cloud integration at the moment.
To be honest, both integrations are ok, but cause of the cloud it is not really the best thing.
There is an api limit, so you the values are not “live” up2date, the need some time.
I live with that at the moment, but this is a thing, thats makes me sad about vaillant and if this persists, the next device will never be a vaillant again for me. For my heat pump a have no really choice because of the installateur, so its for this ok for me and i have to live with it.

I really hope, vaillant changes it mind and allows a local api or at least gives a good documentation on the eebus infos.
As i have warranty, i am not allowed to tingle with ebus directly.

Ronny

[psfshr (Paul Fisher)]

I’m in the same status. I did plan to hook something into the eBus and do everything locally, but my installer didn’t seem too impressed at the idea, and I don’t want to risk my warranty, so am on the cloud option. It’s not ideal, but it’s “good enough” for what I want (mainly monitoring).

Vaillant seem to have gone down the eebus (not eBus) route for connecting locally, so I’m hoping that someone eventually manages to get HA talking eebus at some point

For now I’ve switched to the newer VaillantCloud, and I’ll just need to keep an eye on updates to both…

[ynnor666 (Ronny)]

There is an eebus-go variant, but vaillant has no endpoints, thats all vaillant proprietary and no documentation available,so cloud it is atm,
poorly.
I also do monitoring mainly and will install a additional power meter for me (so i can compare the values )

ebus is spoken locally on the vaillant system and eebus is an interface from lan/wlan to this ebus interface.

Lets see, how this is going on the next time, at least there are more uses with this and i am not alone

Ronny

[romal (Robert M. Albrecht)]

There is an open source eebus implementation. But Vaiillant does not document their use cases based on eeBUS either.

enbility

But it works, I can install and pair it with my Vaillant Arotherm. But then nobody knows the application level language.

I switched to Vaillant Cloud but both in Vailland Cloud as in myVaillant I do not know how to track the energy consumption. I’ve integrated my Vaillant aroTHERM plus and Vaillant Hydraulikstation into Home Assistant using the official myVaillant integration. The following entities are available:

• Vaillant aroTHERM plus Consumed Electrical Energy Domestic Hot Water
• Vaillant Hydraulikstation Consumed Electrical Energy Domestic Hot Water
• Vaillant aroTHERM plus Consumed Electrical Energy Heating
• Vaillant Hydraulikstation Consumed Electrical Energy Heating

However, all of them show only a constant value throughout the day, even though the heat pump is running. The graph in Home Assistant is just a flat line. I assume these are cumulative energy sensors, but they don’t seem to update frequently.

I’d like to:

1. Use these sensors in the Energy Dashboard to track daily/weekly consumption.
2. See meaningful daily graphs of energy usage over time.

My questions:

• Are these sensors compatible with the Energy Dashboard?
• Is there a way to make them update more frequently?
• Should I use utility_meter or statistics sensors to get usable values?

Any advice or experience with this integration would be greatly appreciated!

Thanks in advance,

[SebastianM]

not much going on here in the community…

ChatGPT recommends the following solution:
The sensors provided by the myVaillant integration appear to be cumulative energy meters (total consumption), but they likely update only infrequently – maybe once or twice a day. That’s why the graph appears as a flat line.

To work around this and use them effectively in the Energy Dashboard, follow these steps:

1. Ensure the sensor has the correct attributes :Use customize.yaml or the UI to set:

homeassistant:
  customize:
    sensor.vaillant_arotherm_plus_consumed_electrical_energy_heating:
      device_class: energy
      state_class: total_increasing
      unit_of_measurement: "kWh"

1. Do this for each relevant sensor.
2. Restart Home Assistant, then go to Settings > Energy > Electricity Grid and add your Vaillant sensors as consumption sources.
3. Optional: Create utility_meter sensors If you want to track daily/weekly/monthly usage:

utility_meter:
  vaillant_wp_heating_daily:
    source: sensor.vaillant_arotherm_plus_consumed_electrical_energy_heating
    cycle: daily

This setup allows you to visualize meaningful usage trends, even if the original sensors update slowly.

Let me know if anyone has found a way to increase the update frequency!

[ynnor666 (Ronny)]

Since today, the current_power entities are missing, yeasterday they were there and today the are no longer be provided by vaillant cloud, after a reload this persists (HA 2025.7.4).
Perhaps the Vaillant Cloud does have an issue, as the app did also not show anything.

EDIT: The current_power entities are working again after 1-2 weeks,so this was for sure a vaillant cloud thing. As they were also not visible in the app.

Just installed and it perfectly works. Thanks for great job.

Integration is great and working with eco tec 635 boiler with sensocomfort controls.

Question re hot water circulation pump. Ideas on how to control it through home assistant? It shows here but doesn’t appear to show on when switched on ie when water is heating.

Also can’t seem to see the boiler status ie on and heating water etc.

Any help would be great

[SebastianM]

Hello all,

I read several times that all is great, so my question is: is it possible to track the consumed energy in the energy dashboard or do I have to install a three phase Shelly to get this information… can you share some screenshots?
