FAQs

1. Why does my Visonic Window/Door Sensor continue showing up as a "thing"? I cannot get it to pair properly.
If your Visonic Window/Door Sensor continues to show up as a "thing" in discovery mode, this usually indicates that the device was put into discovery mode before the device handler was created. Please follow the Connect to SmartThings instructions above in the order they are written up to step 8. At that time, (1) remove the “thing” from your SmartThings app and (2) reset the sensor according to the instructions in our Troubleshooting section below.

2. I completed the Connect to SmartThings instructions and put the device into discovery mode but my sensor is not seen by the SmartThings App.
If this happens, please try to reboot your sensor according to the instructions in our Troubleshooting section below.

3. I can't sign in because my hub isn't showing up on My Locations in the Developer API. What can I do?
If you find your hub is not listed under My Locations, its likely you're not using your current login and password info from your SmartThings App. Please create a new account using your SmartThings App login information.
