Zehnder ComfoConnect component

Configuration
77

I don’t see any updated comfoconnect app in the store ? So I wonder where you got the new comfoconnect app from that allowed you to upgrade the firmware.

Can you maybe provide the apk ? So I can at least upgrade my q600 too. This 0-value problem is there for months and I still don’t have a solution. The firmware upgrade you talked about was almost a month ago? and I still don’t see any update. I have both iOS and Android devices. None of them suggest an update or anything. There’s no firmware upgrade option anywhere I looked

78

I’ve joined the beta program and that provides the updated APK. I’ve read that some people have succes with contacting Zehnder support.

You can register for the beta an the link below, but I thing they are close to a public release, so not sure if they still accept new beta testers.

Ebay Germany. Not much cheaper though

Is anyone else seeing problems since recent HA updates?

I’ve spend some time in rewriting the integration and the underlying library to communicate with the Comfoconnect LAN C (it’s asyncio now).

This integration supports the following additional features over the existing integration:

  • Configurable through the UI.
  • Allows to modify the balance mode, bypass mode, temperature profile and ventilation mode.
  • Changes to fan speed won’t be reverted after 2 hours.
  • Support to clear alarms.

But since it’s a big change, it could use some testing before I can submit this to Home Assistant.

If you want, you can install the update trough HACS.

See GitHub - michaelarnauts/home-assistant-comfoconnect: Home Assistant integration for Zehnder ComfoAir trough a Zehnder ComfoConnect LAN C. for more information.

Looks good, but can the power usage be restored?

84

You can, you need to go to the integration screen, and enable the sensor. Not everything is enabled by default.

Ah,got it. Hadn’t seen those. Cheers

86

I don’t see where I can do that. Can you please explain a little more? And I don’t see a current Rmot sensor, is that correct?

87

It’s in the device page. Scroll down to the diagnose section and click the link to open the hidden entities.

Michael, this is great, thanks a lot!

Installation was smooth over here and it seems to run fine for now. Will report back in case of issues.

Being curios, any specific reason why you removed the “comfoairq” part of entity names? It was quite convenient for searching in general and to use with a wildcard to show all sensors by comfoairq_*

89

That was not the purpose, but I’m not sure what change triggers this. I hope to keep the old way (sensor.devicename_sensorname).

Also, there is a away to keep the sensor history, but I need to do some migrations for that I guess. Things to look into later.

When manually setting fan speed to a specific setting, is there a way to hand over a timeout as well, after which it reverts to back to the auto schedule value?

Besides - do you intend to implement away and boost modes as well to the integration?

Great piece of code, btw :slight_smile: Thanks!

Briliant Michael. I just got the LAN C unit and immediately installed via HACS. Working perfectly!

92

One question, I have several RF sensor attached to my ComfoAir. Is there a way to get these values (eg CO2 level, humidity).

Cheers!

93

I guess it should be possible, but I don’t know how to read the values. I don’t have any of those on my unit, so I can’t really test it.

94

No worries, the thing is I don’t see them in the official ComfoConnect either; so was wondering if I had done something wrong in setting them up.

They do seem to work because I can control the fan speed. And since they are ridiculously expensive I was hoping to get a bit more out of them. I have the RF versions.

Keen to hear if anybody has experience with these. Thanks!

I’ve had some contact with zehnder people, the RF ones don’t show any values of the CO (got the same here), they only help to control the ComfoAir. The 0-10v versions connected to the option box can be red through the app (and maybe HA), you can see those values a little lower on the status page of the zehnder app.

If I knew that earlier, I would have bought a 0-10v set, but since everything is installed and all electricity is done, it’s not possible 8-/

Is this version of the Zehnder integration going to replace the original one? Really looking forward to use most functions of the Tasks tab of the zehnder app in HA (preferably the away and temp profile)

Edit: just installed the integration: Everything works perfect! I’ve added ‘comfoairq_’ to all entities, so nothing needs to be changed from the original integration. Keep up the good work!

Hi Roelv, same here now reading this. All installed and no way I can pull wires from the various RF sensors to my ComfoAir. I am considering replacing the RFs with an ESP, this gives me insights and more control over what happens when.
