[App][Pro] Viessmann App for Homey Pro

Hi ,

I have a feature request. I’m using an older type viessmann Vitodens (300W WB3C) with the opto2 module, and a lot of datapoints are not supported (gas use, pressure etc), mostly data points in heating.gas.consumption.
Is it possible to automatically hide data points if they are not reported as supported?

I would like to also have the solar boiler data included.

These data points are:

  1. Collector Temperature: heating.solar.sensors.temperature.collector (Property: value)
  2. Solar DHW Temperature: heating.solar.sensors.temperature.dhw (Property: value)
  3. Total Solar Yield: heating.solar.power.cumulativeProduced (Property: value in kilowattHour)
  4. Solar Pump Status: heating.solar.pumps.circuit (Property: status)
  5. Solar Recharge Suppression: heating.solar.rechargeSuppression (Property: status)

Thanks for looking into this!

Hey Essquare,

I’ll see what I can do to hide data points which are not supported by the device. I’ve added issue #52 in the backlog for this.

The solar boiler data is that from your VItodens, or is that a separate device? If so, how is that one called? I’ve created issue #53 for this.

Hey @Essquare

I’ve pushed a test version (v1.6.0) which should include your changes, can you check how it responds?

You can install from : Viessmann | Homey

Kind regards,

Is there any chance to get the solar pv data from the vitocal heatpump?

Greetings Frank.

Hey @Frank_van_leeuwen

Probably yes - do you have any idea which data points you would like to have exposed? You can view all of them here: Viessmann Documentation

A features.json from your system (available from the option) can be additional help in implementing this.

Kind regards,

Hey Kenny, I don’t know if you got my feedback through the bugreport system but solar data is working for me now. Gas use (unsupported for my Viessmann) is also hidden. Thank you!

Great to hear!

Hi,

Today I noticed that my gas boiler stopped responding to commands from Homey. My Flows also stopped working. It seems this happened sometime during the day.

I tried:

  • reinstalling the app

  • removing and adding the devices again

  • generating a new Client ID

Unfortunately, nothing helped.

The device is added correctly in Homey and all parameters are visible. Also, changes made in the ViCare app are reflected in Homey after a short delay, so read access seems to work correctly.

The problem is with write access:

  • changing the operating mode in Homey does nothing

  • changing the target temperature also does nothing

  • after a short while, the value in Homey reverts to the value currently set in ViCare

Additionally, the mode labels now seem wrong.

Homey currently shows:

  • Automatic

  • Heating

  • Cooling

  • Off

Previously, it showed:

  • Hot water only

  • Heating and hot water

  • Off

So it looks like Homey can read values, but cannot write changes, and the operating mode mapping may also be incorrect.

Thanks.

Hey @Radoslaw_Faruga

I don’t know what has changed, but I suffer from the same. Judging from my debugging it appears all commands which could be send are disabled right now. It somehow appears that we have a read-only api now.

As there are no changes documented in the API, I really wonder what is going on.

Is this an error on Viessmann side? Is this something that changed that they didn’t document?

For now, I’m without clues, but I’m assuming everyone has these issues right now.

Hello all,

I’ve been digging on the Viessmann forums and it seems a global issue with every integration with the Viessmann API.

Viesmann has removed write access to the API, without communication. We don’t know if it is a bug or an intentional move. They did not communicate at all on it.

Here are some topics (in German), on the Viessmann community forum:

Unfortunately there is not a lot I can do at this moment. This will apply to all integrations of the Viessmann API, and also for the other ViCare integration in Homey.

@Doekse , maybe something Homey itself can help out on and try to get some info from Viessmann?

Kind regards,

Thanks for the heads-up. We’re also trying to get in touch with the Viessmann team, although they’ve been fairly difficult to engage with in the past.

The problem should be resolved at least it is for me. Hopefully for everyone.

Hello Kenny,

You made a remarkable job!

I have a Vitocal 205. Would it be possible to command the leave/holiday mode from your app?

Many thanks!

Regards,

Jérôme

Hey,

There is an option inside the API to control the holiday mode, I did not expose this yet, as I do think it is worthwhile to configure this by means of Homey instead.

I personally don’t rely on the programs of Viessmann itself anymore.

Any reason why you want to use those programs explicitly?

Kind regards,
