### 2/5 — New FW /App broke local connection.

*2025-01-24, version 1.9.0*

It used to work great but after a an app update and recent service (can’t remember if they did a firmware update on the unit or not) I logged into the app for the first time since changing season at the end of summer and now it fails to connect and tells me to join the local network. I am on the local network! Only way to connect to unit is on 4G these days for some reason.

### 4/5 — Feature add on.

*2024-05-19*

I wish there was an option to schedule the bypass function.

### 3/5 — Nice app, but…

*2023-12-06, version 1.8.1*

Nice app but missing some features on the programming side (to better automate analogue sensors that have been added and make them play nicely with scheduling features).

Also periodically hangs at the ‘connecting’ step, which requires me to disconnect the ComfoConnect module to force a reset before it will work. This failure should be able to be automatically recovered since there is no direct control of the ComfoConnect module. This — in particular — is very clunky / frustrating and stops me from giving a higher score.

### 4/5 — Good App, but a few missed opportunities

*2023-03-16, version 1.7.0*

The Zehnder Q Series HRV has so many incredible features and the app definitely allows you the ability to do a lot. 

But it feels like it is missing some features that would make it incredible.
Some off the top of my head would be the following: 

- The ability to activate and deactivate at set times through the scheduler 
- The ability to adjust the length of your boost time, when pressed at the switch
- Weather forecast integration
- Having to go into the unit status every time to check all 4 of the air temps is slow and clunky

Not a huge deal, but adding these features would make for a better user experience.

### 4/5 — Decent app

*2022-10-26, version 1.7.0*

Great little app and certainly beats having to go to the unit personally when you want to change modes etc.. 

The scheduler could be a little better, at the moment you have to go through each day setting the time when a nice repeat function would do the job. 

If I was being picky then the ability to switch to dark mode would be really nice

### 1/5 — Only one device connects

*2022-07-10*

I connected my iPhone no problem but my iPad cannot find the system.  The iPhone and iPad are on the same Wi-Fi network that is hosted by the router where the interface box is connected.  All app settings on iPad are the same as iPhone.  Also cannot connect my wife’s iPhone or iPad.  Very inconvenient when my wife needs to use my phone to change settings.  Please update to allow multiple devices.

### 4/5 — Definitely nice to have

*2022-05-09, version 1.6.1*

This is a handy app but doesn’t have the facility to view historic data and doesn’t seem to have the firmware update option mentioned in the instructions for the ComfoConnect Lan C.

### 1/5 — Bug Fixed!

*2021-03-28*

Bud to fix the schedule was fixed!
Yey!!!
The bug that stops your hub connecting to the app still exists so it’s still useless!!!!!!!!!
Not happy

**Developer response:** Dear Nath, Thank you taking the time to write you review. I am sorry to hear about the connection problem. Please consider subscribin to our beta program for the Zehnder IoT Cloud that includes our newest app version and firmware for the ComfoConnect LAN C. You can do so at: https://www.international.zehnder-systems.com/connected-products . Probably this will improve the situation and if not we can give direct support. With kind regards, your Zehnder App Team

### 5/5 — Upgraded review

*2021-01-02*

I previously wrote a review saying nice concept but...
In the last couple months Zehnder has fixed the app and it does everything it was sold as doing. It now works with my Viasat Satellite Internet service at my off grid home and works on the local LAN.
I’m happy enough with Zehnder, my LANC internet connect to my Q600 unit that I bought another identical system for another structure I have, a heated garage with living space above.

Very satisfied, but even more important I’m really happy they improved the app and made it work. They obviously care about supporting their products.

**Developer response:** Hello Goldco, thank you for your updated feedback. Good to hear that it works as expected now. With kind regards, your Zehnder ComfoControl App team

### 5/5 — Amazing

*2018-06-07, version 1.1.0*

Great
