Hello to the community, I have now searched for a long time and found nothing. I would like to have a flow which tells me when a light is turned on or off in a certain room. Without motion detectors or the like. Can someone give me a tip? ---

**When…** – (Light) Turned on **Then** – Notification: “Light is turned on” **When…** – (Light) Turned off **Then** – Notification: “Light is turned off” ---

Hi fantross, I don’t want to have to dial every single light. I would like to query every single light in a room that is declared as a light. I would also have andvanced flow. ---

That’s not what you asked for. So next time please provide a little more and precise information. Thank you. As far as I know, there is no way to query multiple lamps with only one trigger card like “This zone became active” based on lamps, maybe with a Homey script. And the mentioned flows can be converted 1:1 into an Advanced Flow. ---

Hello, I’m sorry if it was asked incorrectly… am not quite fluent in English and always have it translated. OK I think you answered it but that it does not go so with flow but possibly with a homey script. I will deal with Homey Script. Thanks anyway for your answer… ---

You can make a request to developer Arie in [this topic](https://community.homey.app/t/app-pro-device-capabilities-enhance-the-capabilities-of-devices/43287) Like, for zones, this card is already present: ![Screenshot from 2023-03-14 15-02-12](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/b/9/b98235b992f9f953f37b9150571bd944032f0786.png) Maybe he can create a similar card but then like “When a [device\_class] in [zoneName] went [on|off]” ---

You can put all the lights in a room into a group using the \ app. Works fine. ---

Just make sure to set it so groups on/off is set to “on when any lights are on”. Rather then on when all lights are on. ---

As per suggestion by @Peter_Kawa : there is a great app called Zone Activity
