Device Discovery Troubleshooting

Konnected devices are discovered automatically by your smart home hub using a UPnP (Universal Plug-and-play) protocol called SSDP. If you're having trouble discovering your Konnected devices, it's usually a network or router related problem. We've found that these troubleshooting steps can solve most problems:

Your SmartThings hub or Home Assistant box need to be on the same LAN or subnet as your Konnected WiFi devices!

  1. Enable UPnP in your router settings.
  2. If your router has a setting called IGMP Snooping, disable it.
  3. If your router has a setting for IGMP Proxy, try changing the setting and rebooting the router. Different routers implement this differently, but usually it is not required.
  4. The discovery process uses multicast traffic on your network originating from your hub that must reach your Konnected devices on WiFi. If you have an advanced network setup, such as a separate subnet for wired LAN and WiFi, make sure that multicast traffic can pass.
  5. SmartThings Users: Make sure you have installed the Konnected SmartApps on the local server for your SmartThings hub instance. The URL in the address bar of your browser when you're in the SmartThings IDE should have a regional identifier, such as graph-na04-useast1.api.smartthings.com. If the URL only contains graph.api.smartthings.com then you have not set up the SmartApp correctly. Please go back and re-do the SmartApp installation steps.
  6. If you have multiple routers, make sure that they are bridged properly to form one network.
  7. Check the logs.

    SmartThings: Open the Live Logging tab in the SmartThings IDE and filter for messages from the Konnected app. you should see some log messages like this when discovery is working properly:Home Assistant: Check your home-assistant.log for messages from the discovery component that look like this when working correctly:
  8. When all else fails, reboot the hub, router and Konnected devices and try again.

    Reboot a Samsung SmartThings Hub (Hub v2) by pressing the recessed red button on the back of the Hub once. Wait 5-10 minutes for the LED to turn solid green; this will indicate the Hub is back online. If you have Hub v1, reboot the Hub by unplugging it and plugging it back in.
