Hi, I have a number of light switches/dimmers in my house, from Shelly, EcoDim and RobbShop. I’m trying to figure out if you can tell, in a flow, if a switch/dimmer was activated by pressing the button, or by Homey. Basically, when a ‘Turned On’ event is triggered, can I tell how it was triggered? I know I could do it with a lot of variables, but is there an easier/built-in way? Cheers, CJ ---

You can, by using the [Device Capabilities app](https://community.homey.app/t/app-pro-device-capabilities-enhance-the-capabilities-of-devices/43287), but you’ll have to create this flow part for each device you want to monitor: ![Screenshot from 2023-06-02 16-02-17](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/2/f/2fb24f5d5ce7d9388fb36b041b79bf421a7e7ede.png) But are you aware of the mobile app’s device log (longpress a device to view it), this is automatically done by Homey. This also shows flow names when a device is commanded by a flow: ![Screenshot from 2023-06-02 16-04-56](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/c/a/ca128cc46dedc80edb7601c2dc9090bd3609759c.png) ---

Hi, thanks for the reply! I’ll look into the Device Capabilities app. Yeah, I know the log shows it, but I want to use that information in my flow. So, for example if a light is activated by a motion detector, or by pressing the button on the wall, different things should happen. (I know I could probably fix this in the flow that’s triggered by the motion detector, but my flows are set up differently - kinda hard to explain). ---

YW! > [@CJ\_Scholten](#): > > but I want to use that information in my flow Ah okay, yes then my example flow can come in handy ---

or create and ad in your flow a variable, triggered, yes or no, these you can also use in the insights. so many roads to Rome…
