I’ve made this once for contact sensors, usable for blind statusses as well: > [@Share Your Device! - Advanced Virtual Devices from Device Capabilities](https://community.homey.app/t/share-your-device-advanced-virtual-devices-from-device-capabilities/68676/88): > > This device + accompanying flow shows the status of 3 door/window sensors. > It’s **off** and shows `0 #Open` when all are **closed** > It’s _ **on** _ and shows `1 #Open` when _ **1 is opened** _ > It’s _ **on** _ and shows `2 #Open` when _ **2 are opened** _ and so forth > > Device tile: > > ![signal-2024-03-02-042457_002](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/7/0/7041c0398d0e12cff55821a723a1a9182faa58d2.jpeg) > > ![signal-2024-03-02-042457_003](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/0/5/05f4d25bde626b2789fff8d6b40e84cbc5eda373.jpeg) > > All contact sensors overview in the device settings: > > ![Screenshot_20240309-221654_Homey](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/e/b/ebb44696d8165fa421cd8a54aa29ab8a3319fbb8.jpeg) > > Flow: > > ![Screenshot from 2024-03-02 23-11-28](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/5/6/56aa85a9faaeda6c7416af26e7b4fe0e39972e33.png) You’d be able to import the device + flow, look for _TEF_: > [@Share Your Device! - Advanced Virtual Devices from Device Capabilities](https://community.homey.app/t/share-your-device-advanced-virtual-devices-from-device-capabilities/68676/88): > > Master Doors and Windows status indicator This device + accompanying flow shows the status of 3 door/window sensors.

Graag zou ik deze oplossing ook willen gebruiken. Echter er verschijnt niets in Homey na een tef run. Zou deze tef niet meer actueel kunnen zijn en daarom niet werkt? Kan iemand bevestigen dat deze werkt? Translate in google: I would like to use this solution too. However, nothing appears in Homey after a tef run. Could this tef be outdated and therefore not working? Can anyone confirm that this tef works? ---

This should also be possible with a Homey script. When I leave my home I get a message on how many lights/sockets are still on ---

Yes, next to simple calculations you can use many math.js functions > **[math.js | an extensive math library for JavaScript and Node.js](https://mathjs.org/docs/reference/functions.html)** > > Math.js is an extensive math library for JavaScript and Node.js.
