Add control over heat exchanger

Integration name

Duco

Link to integration documentation on our website

https://www.home-assistant.io/integrations/duco/

Describe the enhancement

The target writable properties are:

TempSupTgtZone1
TempSupTgtZone2

And I'd like to use the values form TempOda, TempSup, TempEta, TempEha

All of these are already provided by the API.

Use cases

Especially in summer, the heat exchanger default settings are not comfortable. Ideally I'd want to control it so a colder night allows better in-home cooling even if the temperature inside is below e.g. 23 degrees celcius.

Anything else?

Thanks for the suggestion. I think this is a very interesting feature and can definitely see the value it provides, especially for improving comfort during warmer periods.

I’ll take a look at how this functionality is exposed by the underlying API and investigate whether it can be implemented in a way that fits well within Home Assistant’s entity model and design guidelines.

Small update on this feature request: work has started on bringing this functionality to the Duco integration.

The implementation is currently split into two separate pull requests:

• Adding sensor entities exposing the available heat-exchange and ventilation metrics.
• Adding bypass control support.

The first PR, which adds the sensor entities, has now been submitted:

• Add Duco ventilation temperature sensors core#176621

I’ll provide further updates here as the remaining pieces progress.

Small update on this feature request again:

The first PR, which adds the heat-exchanger temperature sensors, has now been merged. 🎉
The second PR, which adds control over the bypass target temperatures, has now been submitted for review:

• Add Duco bypass target temperature controls core#176820

Current status: the PR is still under review, while the beta feature freeze has already started. This means the functionality will, at the earliest, be included in the next Home Assistant release.
