Hi everyone,

I just created my first Homey App for my light switches. Everything is working as expected but i’m now trying to implement °Settings° panel that should set corresponding ZWave parameters on the device.

I have been able to configure initial Zwave parameters in **driver.compose.json** as mentioned here

“zwave”: {  
“manufacturerId”: 266,  
“productTypeId”: [4608, 4609, 12800, 16896, 28787],  
“productId”: [20992, 20993, 37376, 3956],  
“learnmode”: {  
“instruction”: { “en”: “Press top button to include. Hold the left button for 8 seconds to exclude” }  
},  
“defaultConfiguration”: [  
{  
“id”: 7,  
“size”: 1,  
“value”: 3  
},  
{  
“id”: 13,  
“size”: 1,  
“value”: 4  
}  
],

This anyway works only when i pair my device with homey not when i change settings in device settings page (as expected). No issues here.

Anyway,  
I have been able to understand from docs that if you set parameters within **driver.settings.compose.json** , they should be sent to corresponding device as soon as a parameter is changed in the mobile app but this seems not working in my case.

I have a light switch which has the capability to change button colors by modifying the corresponding Zwave parameter. If I change the corresponding settings (within device settings page) with another value, this is not reflected on the device.

If i put same parameters within “ZWave Raw configuration parameters” like this: 7,1,4  
this works perfectly well and immediately.

If I select this particular option from the dropdown in settings page, this parameter seems never sent to the device and button color remains the same:

Here you’ll find the corresponding part in **driver.settings.compose.json**

{  
“id”: “7”,  
“type”: “dropdown”,  
“value”: “0”,  
“label”: { “en”: “Off Button 1 Color” },  
“values”: [  
{  
“id”: “0”,  
“label”: { “en”: “Off” },  
“value”: “0”,  
“zwave”: {  
“index”: 7,  
“size”: 1  
}  
},  
{  
“id”: “1”,  
“label”: { “en”: “Red” },  
“value”: “1”,  
“zwave”: {  
“index”: 7,  
“size”: 1  
}  
},

Any suggestion on what to check/modify?  
Am I expecting something wrong?

Thanks,  
Oreste

Hi everyone.

I have been able to solve the issue by myself and, since no-one gave any suggestion, i’d like to share what was the problem and how i solved it.

Basically, after having tried almost everything within **driver.settings.compose.json** i noticed that there was an empty method **onSettings** within **device.js** that was overloading the standard framework function and blocking any action on zwave parameters.

As soon as i removed this empty function from the file, homey has been able to set parameters to ZWave device as soon as a parameter was changed within **driver.settings.compose.json**

I’m now maintaining all parameters within **driver.settings.compose.json** and everything is working perfectly well.

Hope this info can be useful if you are managing a similar case
