You can easily add ZigBee devices to maveo. Go to the settings of the maveo app and add a device.
Put the ZigBee device you want to add into pairing mode. How exactly to do this, you can read in the manual and on the support pages of the device manufacturer.
Select ZigBee devices.
Now the maveo box will start a 120 second process of searching for ZigBee devices in the area. If you have put the device in the right pairing mode, it will be shown to you now. This process can take a few seconds.
Once your device is detected, it is already added. You can then exit the screen, even if the countdown is still counting down.
