+## Gledopto
+Some of the Gledopto devices are not providing a `modelID`, in that case the modelID `undefined` is shown. Sometimes it helps to repair the device while keeping it close to the coordinator (less than one meter). 
+
+If this fails, the `modelID` has to be set manually in `data/database.db`. First find out the `modelID` of your devices from the [Supported devices page](../information/supported_devices.md). Then open `data/database.db` and add the `modelId` as highlighted in **bold** below.
