While adding Insteon devices using Insteon+, you may encounter an alert informing you that Insteon+ was unable to establish a connection with your new Insteon device. There are several reasons why this might occur.
Your new Insteon device is too far from another Insteon device to reliably receive an Insteon signal
The incorrect Insteon ID was entered
Multiple Insteon devices were placed in linking mode simultaneously
Basic Troubleshooting
Try restarting the Add process by tapping cancel. Wait about 30 seconds and then attempt to add your new Insteon device again.
If you are adding a plug-in device, try repositioning it or move it closer to Insteon Hub.
If you are adding a hard-wired Insteon device that cannot be relocated, try temporarily relocating your Insteon Hub. You can also try adding a Range Extender or additional Insteon Plug-In devices between your new Insteon device and your Insteon Hub to extend the reach of your Insteon signal.
When entering the Insteon ID, it is possible to misread some letters. As Insteon IDs use hexadecimal numbering, only the numbers 0-9 and letters A, B, C, D, E and F are found in the Insteon ID. There is no need to enter the separating period or colon. Learn more about locating your device's Insteon ID.
Not all Insteon devices are currently supported by Insteon+. Sensors, WiFi Cameras and more are not compatible with Insteon+. Learn more about unsupported Insteon devices.
