(I’m starting with Homey Script 😉 )
Can you help me ? This script purpose it’s to turn on, all lights in one (or more zone). I did this as a test… but couldn’t find the issue.
```auto
let zoneName = "Bureau";
let devices = await Homey.devices.getDevices();
_.forEach(devices, async (device) => {
if (device.zoneName === zoneName && device.capabilitiesObj && device.capabilitiesObj.onoff) {
// Check if the device is a light
if (device.class === 'light') {
await Homey.devices.setCapabilityValue({
deviceId: device.id,
capabilityId: 'onoff',
value: true
});
console.log(`Turned on light: ${device.name}`);
}
}
});
```
Thanks

I don’t think there’s a device.zoneName property - I’m a novice myself so I could be wrong. I use device.id which returns the id of the zone the device belongs to.
I use the following to get an array of ids and names…
```auto
const zones = await Homey.zones.getZones();
```
and then to get the zone name for a given id, I use:
```auto
let zoneName = 'Unknown';
for (const zone of Object.values(zones)) {
if(zone.id == device.zone) {
zoneName = zone.name;
break;
}
}
```
You could do something similar/better to get a zone id from a zone name.
Hope it helps,
Andy

This works
Edit: for Pro 2019 that is
```auto
let zoneName = "[1.1] Keuken";
let devices = await Homey.devices.getDevices();
_.forEach(devices, async (device) => {
if (device.zoneName === zoneName && device.class === 'light') {
await Homey.devices.setCapabilityValue({
deviceId: device.id,
capabilityId: 'onoff',
value: true
});
console.log(`Turned on light in zone ${device.zoneName}: ${device.name}`);
}
});
return true;
```

It works, it gets ‘proposed’ as well

HP2023 or older Homey?

Sorry, this is @ Pro 2019

Yeah, with older Homey’s, `device.zoneName` exists, for the new Homey it doesn’t 😭

To piss off developers?

I was trying to do something (a bit different) with zones on a HomeyPro 2023, and bumped-into this thread on my journey, therefore offering a quick snippet of Homey Script on this topic for any similar future travellers. I’m sure it can be improved, but it might at least help point the way.
I chose to specifically iterate Philips Hue lights. I presume that could be skipped (or substituted) to control other types with the same device.class.
```auto
// Define string constants for matching Hue lights
let sMatchOwnerUri = "homey:app:nl.philips.hue"
let sMatchDeviceClass = "light"
// Customise this (or pass in as parameter from flow) for desired zone and on/off value to control
let sMatchZoneName = "Study"
let bOnOffValue = true // true to turn on, false to turn off
// Get Homey devices and zones
const myDevices = await Homey.devices.getDevices();
const zones = await Homey.zones.getZones();
// Get zone ID from zone name
var sMatchZoneId = undefined // Initial value
for (var zoneId in zones){
if (zones[zoneId].name == sMatchZoneName) {
sMatchZoneId = zoneId
}
}
if(sMatchZoneId != undefined) {
log("Matched zone name:", sMatchZoneName, "to zone ID:", sMatchZoneId)
} else {
log("Failed to find zone name:", sMatchZoneName)
}
log('\n')
// If zone name successfully found in Homey zones
if (sMatchZoneId != undefined) {
// Create list of matching devices, to enable on/off control in a separate loop, aiming for less delay between devices
let ownerZoneDeviceList = []; // Initial value
log('List of devices with ownerUri ==', sMatchOwnerUri, 'in zone', sMatchZoneName, ':\n')
for (var iMyDevice in myDevices){
const device = myDevices[iMyDevice]
if ( (device.ownerUri == sMatchOwnerUri) && (device.zone == sMatchZoneId) ) {
if ( device.class == sMatchDeviceClass) {
ownerZoneDeviceList.push(iMyDevice)
log(zones[device.zone].name, " : ", device.name);
}
}
};
log('\n')
// Iterate list of matching devices, and control them as needed
// (deliberately in separate loop from the search, aiming for less delay between controlling devices)
for (var iMyDevice of ownerZoneDeviceList) {
const device = myDevices[iMyDevice]
await Homey.devices.setCapabilityValue({
deviceId: device.id,
capabilityId: 'onoff',
value: bOnOffValue
});
console.log(`Controlled light: ${device.name}, setting onoff state to: ${bOnOffValue}`);
}
}
```
