Hi all
I have this device connectet to my garage door.
Works super!
I use this config
type: custom:button-card
entity: switch.shelly_hojre_garage_port
name: Højre garageport
icon: mdi:garage
tap_action:
action: call-service
confirmation:
text: Er du sikker på, at du vil åbne/lukke porten?
service: switch.toggle
service_data:
entity_id: switch.shelly_hojre_garage_port
state:
- value: "off"
color: green
icon: mdi:garage
- value: "on"
color: red
icon: mdi:garage-open
But i also have the device connectet with zigbee.
So how can i build like “If wifi is down” use the zigbee device instead to trigger the opening? 
Hope it makes sense
Regards Daniel
