Hey there,
I’m still struggling with connecting my viessmann central heating to homey pro. To be more precisely: I have connected it via Homa Assistant & the Homey App Home Assistant Community App.
I know that there is (unfortunately) no way to turn the hot water module on/off. I would now like to buy an electric heating module that can use the electricity from my photovoltaic system to heat the hot water in order to save gas. The part is from Viessmann and is basically an immersion heater that I want to connect to a smart socket and control depending on the status of my PV system. What I’m missing now is that I can prohibit the heating system from using gas when the immersion heater is running. As I can’t switch off the module, I would like to try using the target temperature. And that’s where my problem lies: I can’t find a corresponding variable with which I can set this temperature so low that the heating thinks it doesn’t need to heat. Has anyone managed to control the Vitodens DHW heating from Homey?
This is the immersion heater, I’m talking about:

I’m not sure if I’ve understood the problem, but in the end you want to control or reduce the set temperature of the central heating, correct?
Can this be done with the integration in Home Assistant?

Hi Rainer,
I can not answer your question, but maybe it helps anyway.
We have a Vidodens 333-F, which is also connected to Home Assistant.
With that I have the option in Homey to heat up the water one time, and also to change the temperature.
I started to look in Viessmann central heating (over HA) using Homey, so most of functions are still not tested. 🙂

Hi Warmduscher,
I fear that I don‘t have the same Entities. These are my entities that are not labelled as „sensors“:
binary\_sensor.vicare\_burner\_active
binary\_sensor.vicare\_circulation\_pump\_active
binary\_sensor.vicare\_dhw\_circulation\_pump\_active
binary\_sensor.vicare\_dhw\_pump\_active
binary\_sensor.vicare\_frost\_protection\_active
button.activate\_one\_time\_charge
climate.vicare\_heating
number.e3\_vitodens\_300\_0419\_komforttemperatur
number.e3\_vitodens\_300\_0419\_normaltemperatur
number.e3\_vitodens\_300\_0419\_reduzierte\_temperatur
number.e3\_vitodens\_300\_0419\_steigung\_der\_heizkurve
number.e3\_vitodens\_300\_0419\_verschiebung\_der\_heizkurve
water\_heater.vicare\_water
Am I right that sensor-entities can not be changed?

Yes that’s also my understanding that sensors can only measure.
Are there any other entities in HA for Viessmann?
I imported only some entities to Homey with the HA Community App, but I can see in Homey also the type Thermostat and Taste
I’ll back home tomorrow, then I can send you a list of my entities in HA.

You have a button to heat up one time.
This button can be added to your Homey device.
If the button is shown in your HA device, you can easily add these additional entities via device settings.

> New test version 1.2.0: Adding HA device entities to a Homey device: The new version offers a possibility to integrate all sensors/buttons/switches from a HA device into the Homey device. The Homey device is still domain based. So you will still add a device based on its main entity (e.g. vacuum, light, switch or sensor) because the device properties and actions are based on these domains and their attributes/services used in HA. But once you have added an entity to Homey (let’s say a Hu…
As other option you can add the entity manually via repair screen.

Thanks for all the answers so far.
I fear I better should delete and integrate the central heating again into HA. Seems like I’m missing some of the entities. Or is there a smarter way to add missing ones?

The climate entity has current and target temperature. That is what you need.
Add this entity as climate device to Homey via HA community app. The follow one of the linked possibilities above to add the additional sensors/buttons to your Homey device.
The climate device offers all possibilities known from a Homey climate device (depending on features of your HA device).

Hi Rainer,
I checked now the entities in HA, and the relevant ones to change temperature are marked in my screenshot above.
For me it was easy and straight forward to use Ronny’s app, but not used in the moment. Follow the instruction, then it’s quickly done.
Everything else is already mentioned from Ronny.

Hi Ronny
It took a while but finally it worked. I had to refresh the vitodens entities, then the current and target temp appeared,
(There is also a on/off toggle, but this ends in an error message)
Thank you

Hello,
I have made an app for it now, you can try it if you want using [Viessmann App voor Homey | Homey](https://homey.app/nl-nl/app/be.functor.viessmann/Viessmann/)
Vitodens and Vitocal device are supported, other can be added at a simplex request (I will provide instructions on what I need then).
Try it and any feedback is welcome.
Kind regards
Kenny
