Does an app exist that lets you add computers to Homey as devices, on basis of IP and/or mac address? I would like to use it in flows to check if they are on or off and eventually turn them on or off, but I can imagine that there are many more possibilities. I’ve searched the app store, but cannot find an app like this. Any help, also workarounds, would be appreciated! ---

I think I have seen some post about using smart presence app also to detect the computer. You had to install some specific software to the computer or do some other tricks. But I couldn’t find the post anymore (or I have had only a daydream of that function 😉 ) ---

In my Dell computer, i have a Bios option where i can turn on my Pc just by plug in,so i just install a smart plug and i can turn on/off the Pc via Tuya Homey app. Maybe in your Bios you have this option too😉 Or by wake up Lan is an other option ---

I use SmartPresence to monitor all my networkdevices to get a notification whenever a device is offline. You can do the same with your computer. Only need to use fixed-IP adressess. I don’t know whether it’s possible to turn the computer on of off. ---

I use this app on my computer: [http://www.ireksoftware.com/SleepOnLan/](http://www.ireksoftware.com/SleepOnLan/) Combined with this flow: [Shared Flow | Homey](https://homey.app/f/XSNgyu) Which makes my computer go to lock screen when no one has been moving around in my office for 30 minutes. Activity in the office is detected by a unifi camera, but you could use any motion sensor, and of course make the computer sleep or shut down completely. I only use this because I have noticed something is often preventing my computer from locking itself automatically the way it’s supposed to. ---

I have got a Netgear router which has also an app/is implemented in Homey. With this app I can check if a device, in my case also my computer, is online, when the ‘fixed’ IP adres is online. Then I start flow. When the IP adres is not visible anymore, the computer is off and the scene will be different. ---

Works like a charm to detect if the computer is on or off. Turning the pc on or off remotely is a next step, but I’m already very happy with this solution! ---

Port 32000 didn’t work for me, somehow the firewall in Windows 10 blocked this. Setting the port to 7680 did the trick. As the PC’s are connected by a cable, I’ve set the Away Delay and Normal Mode Check Interval tot minimum values (1/1500). Works like a charm! ---

The ports 32000 and 7680 didn’t work for me. Does somebody have idea what to try next? ---

Does anybody know what port to look for that can be detected by SmartPrecence? Windows seems to be blocking 32000 but also 7680. Any help would be appreciated. ---

Hello, I just solved this issue. Just use commnad netstat - aon to find out which ports are open. Look for PID 4 - thats system booting up. Use that port. I tested it on windows 7 10 11. ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/6/3/6326710332f9967a93ff371b2efdabfb4eb9664f.jpeg) ---
