Zehnder ComfoConnect component

is there a config parameter how for a refresh interval?
Seems like now it is updated like every second which is not needed for my use case and I would like to set another interval.

Cheers

I also have a Q350 + ComfoFond and have the same issue where home assistant only showing the out side air temperature as post ComfoFond. Looking through the information on github https://github.com/michaelarnauts/comfoconnect/blob/de1a118425724364919dd99c62d05a45fd11827b/PROTOCOL-PDO.md the sensors on the ComfoFond have been identified as No. 416, 417, 418 and 419. Does anybody know how to add these.

Hi’
Is there a way to link multiple Comfoconnect devices in HA ?
If I try this :

comfoconnect:
  - name: 'Ventilation salons'
    host: '10.2.100.8'
  - name: 'Ventilation bureau'
    host: '10.2.100.9'

I get a configuration error.

Hai Marius, old post but maybe still good to know:
Zehnder delivers multiple ways to steer the unit. You can manually control it or connect several other sensors such as CO2 and presence/humidity sensor. Thing is, these sensors from Zehnder are really expensive. I think with HA you can use also good but much cheaper ones to make the unit work really well. I have worked at Zehnder for 7 years and know the products rather good. Thing is, the software integration isn’t something they are leaders in. But on the other side, so aren’t other manufacturers of these kind of units…

yeah, I was deciding between Zehnder and Brink. Of those, I believe the Zehnder was most advanced… On devices like that, I dont want to fiddle around too much with cheaper hand made things, because 1) I need warranty from the manufacturer and 2) need them to work stand alone too, without any HA interference.

Good to hear you have a long experience with them, maybe you can advice what unit to use and which connective device to choose, considering I want co2 and humidity sensors attached to trigger the unit?

Since the Zhender Q-series has a lot of information to share to Home Assistant I was missing overview:

So today I made a picture elements card to give me the important information in a glance:

Great entity; thank you! Can you also provide the code for the buttons underneath?

It’s a horizontal stack with custom:button cards. Works as follows.

scripts.yaml:

  icon: mdi:fan-auto
  sequence:
    - service: fan.turn_off
      target:

  icon: mdi:fan-speed-1
  sequence:
    - service: fan.set_percentage
      target:
        entity_id: fan.comfoairq
      data:
        percentage: 33

wtw_preset_2:

      data:

I have some other scripts under the long-press to run the fans for 30 minutes on a certain level and cancel other settings (fans spin up automatically here on some input from a shelly temperature measurement on the warm water pipe) but for the basic functionality you can just ignore this :wink:

edit 16-04-2022: as the low/medium/high settings for fans are no longer available rebuild the buttons to work with percentages.

Very Nice!

Hi,

The iOS has been updated at some point and now allows you to set ‘Away’ as a status for the Q350. It would be great if the integration supported this, if at all possible?

Presently my automations set my MVHR entity to ‘Off’ when we leave the house but the damn thing turns itself back on again when it needs to. This is annoying in the winter especially because the preheater kicks in and uses a tonne of energy when the house is empty! I’m looking for a way to prevent this short of adding a smart plug and just killing the power when away.

Does anyone have any other thoughts?

TIA

hey @breinonline
very cool card.
could you tell me where the “d” is coming from?

Edit: never mind its coming from the sensor value … well does not my language :smiley:

Depending on the language the sensor displaying the number of days remaining until replacement of the filters is needed might be another character I guess :slight_smile:

This is mine:

I have a couple of RF sensor attached to my comfoair. Do you know if it possible to read the value (eg co2 and humidity)? Keen to track and use these for further automations. Thanks!

I was also wondering today if Tado sensor with humidity recording could be sent to Zehnder units to initiate a speed change, or if this is best left as an automation?

That’s exactly something for an automation.

Zehnder has finally pushed a new Comfoconnect app (for Android) that fixes a firmware update issue so it finally allows to upgrade the bridge to 1.5.1.

This firmware fixes the 0 values issue. I was running 1.3.0 before and had the 0 values issue.

Whats the 0 value issue please?

Every hour or so, the bridge would report a 0 value. See https://github.com/michaelarnauts/comfoconnect/issues/44

Too bad I’ve already purchased a ComfoConnect KNX and not the LAN version. Has someone implemented the Comfoair with it already? Have successfully integrated KNX lights and other sensors, so I’m positive to integrate the Comfoair sensors but what about the controls? Only chance to use switches?

Thanks!
