Wigets solo funciona dispositivos wifi

Hola porque los Wigets sólo podemos utilizar dispositivos wifi y no dispositivos zigbee

This is something not even the oldest developers at eWeLink know. One of the many quirks you may come across. Get used to it :man_shrugging:
You can get around this by creating a Tap to run scene to operate the Zigbee device. For example, you set reverse mode for the switch and put a widget on the desktop.
