[RELEASE] Neo Coolcam / MCO Z-Wave Light Switch

Hi @Khaled_Qari, any updates on the 3 gang DTH?

Well, I actually am waiting for someone to help me in this matter since I am using the original DTH it’s working pretty well so far only thing is i can’t get the extra setting i get with this DTH

I would love that as well @Sebastian_Iaconis

I’m waiting for the 3-gang switch to arrive and I can test and update the DTH.

I am new to the community; I am in the middle of doing my electrical network in my house and I am considering a zwave solution for lighting based on Neo Coolcam 2 and 3 button switches.
I have seen that you have developed a DH for 2 button and will start playing with it in the next few days; any news on a DH for the 3 button switch?

I’m afraid I do not have an ETA for the 3-gang switch DH.

The 3-gang switch is using a newer Z-wave Multi-Channel version than ST, and I’m waiting for a response on it - Does SmartThings support the latest Z-Wave Multi Channel version?

Hello, I bought a neo coolcam 3 gang switch but its not working for some reason. Is there a DH for the 3 gang switch. Your help will be really appreciated.

No. It will NOT work with the new NEO Coolcam 3-Gang switch.

Guys, i installed 24 switches of this in my new house, they are look awesome but this small press delay is SHIT!
Every guest who is coming to the house and trying the switch has a small problem with it.
EVERYONE is pressing it just for a moment, and because the switch has this 1 sec delay , they pressing it immediately again (because they think the first press was wrong) so the switch is turning ON and immediately OFF or doing nothing.

I cannot believe that NEO sold thousand of switches and there is no change in the software…

Are you guys OK with this delay?

Brian, I´m pretty much in the same boat as you where a while ago, house renovation and need 20-30 switches for the EU market and these Neo Coolcams seem to be the only real option at the moment except for Fibaro switches which i dont really like the design of and the price is over the top.

Have you abandoned the Neo´s or made any improvements to them in any way?

§any luck or anyone find solution for this 3ch issue

I would like to ask if you can check “neo-coolcam-light-switch.groovy” & " neo-coolcam-light-switch-child.groovy" because the second switch the child (2 channel switch) stop working. I’m not able to switch it on/off via webcore nor via SmartThings Classic app. It also doesn’t work from the new SmartThings app.
I’m using the EU version of 2 channel Neo Coolcam light switch on SmartThings hub v3 with latest firmware 30.3.
Thanks in Advance

@Ervin_Narancsik - It appears to be firmware issue.

@hongtat - Thanks for the reply.
Meantime I tried another DTH released by @krlaframboise [RELEASE] Neo Coolcam Light Switch 2CH and I can confirm it is working fine with the current firmware (30.3) issue related to multichannel switches.
Lets wait for fix from SmartThings support.

Hi, i’m facing the same problem as you with delays.
They are using https://www.holtek.com/documents/10179/116711/BS81xA-xv150.pdf chip for sensors and in three gang switch it can be increased. Not 100 percent sure about 1 and 2 gang as i have they with 2017 revision and there is too tiny chips soldered

A recent breaking change by SmartThings may cause the child device not responding to on/off action or show correct status in the New SmartThings App.

It may also not discoverable in the new Google/Alexa integration.

If you have NEO Coolcam or MCO Zwave light switch (with 2 or more channel/gang) - please

  1. Update the code from here.
  2. Login in to IDE.
  3. Under “My Devices” tab, find and click on the child device.
  4. Check the “In Use by” column, if this child device is in use by other apps (e.g. Automations, SmartLightings, ActionTiles, WebCore, etc,) - remove them. This column must be empty before you proceed to the next step.
  5. Click the “Delete” button to delete the child device.
  6. Find the parent device of this child.
  7. In the parent device, click the “Edit” button, and click “Update” button.
  8. A new child device will be created and it would appears in the new App and Google/Alexa correctly.

The Child has Type “placeholder”

It switched one time to On and is now offline acc the app.

Do I need to change Type of the Child?

Can you try replacing the “Z-Wave Light Switch Multichannel” with the Neo Coolcam - Parent & Child and delete & add the device again?


YES! Works immediately.

The parent & de child.

Tnx for the fast solution.

I have 4 channel MCO, I removed it from the hub and now when I added it by default it chose Z-Wave Device Multichannel. I edited it and selected “Zwave Light Switch MultiChannel” and update. no childs has been created. I updated the handlers for both the parent and the child.

Can anyone help?
