[App][Pro] MCOHome App (v1.4.0 | TEST v1.5.3)

You probably have a second account where you Homey is connected.

I have got life in to it by logging out of both instances, closing the browser and then logging in again. Thanks for your help, it is much appreciated

I’ve just released v1.5.2 to the test environment of the app store: MCOHome | Homey

This release is based on SDK3 (compatible with Homey Pro (Early 2023)) and adds support for the MH8-FC4 and C421 shutter panel.

Since I don’t have all MCOhome devices, I could not test all devices. Please report back if issues arrise.



Any news on the released v1.5.2 test ? unfortunately I can’t test it yet as my Homey Pro doesn’t arrive till February - all my light switches in the house are MCO Home so would be able to test fully

I had some issues with my MH7H Thermostat and the v1.5.2 test version. But @TedTolboom fixed them really quick and they work now with no issues with the v1.5.4 test version.

Actually there is no reported issue on GitHub with light switches, so I guess they will work But of course I don’t know, if someone who is using MCO switches has already updated the app.

Thanks for the info

Hi @TedTolboom ,
Any chance the non-neutral 2 Gang switch, MH-S312-SL, will be supported soon?


The MH8-FC4 thermostat added as basic z-wave device, i tried twice and i got the same result.

which Z-wave ID’s are shown in advanced settings when added as a basic Z-wave device?

I have spare piece of thermostat that i cant send to you.

Hi @TedTolboom ,
Just installed a non-neutral 2 Gang switch, the MH-S312-SL and was not recognised.

Product Type ID is the same as the neutral version, 12578. But it’s have a new Product ID 28930.

Appreciate if you can add the support.

Hi @TedTolboom,

After I’ve moved to HP23, I’m getting the message “TRANSMIT_COMPLETE_NO_ACK” when toggling my MCOHome touch panel switches. eg. toggling a switch via app, toggles on/off the switch successfully, but then I get the message “TRANSMIT_COMPLETE_NO_ACK”, and the status revert to the last status on the app.

Anyone encountered this? Any advice?



Hello @fantross,

is there a solution to this problem meanwhile? I have 10 MH7-WH and it really sucks to adjust time on them manually every two weeks (because by then 2 of them are running min, 3min ahead of time)

No, unfortunately not. Changing the time using Z-Wave raw configuration is not possible in my opinion. But I have just written an email to MCO.
