Swing Gate sensor

Hardware
2

I purchased a MimoLite ZWave relay (Amazon.com: Wireless Z-Wave Multi-Input/Output Dry Contact Bridge; Cert ID: ZC08-16040002) that I have connected to my HA for just this. Allows both sensing if open / closed, as well as trigger the opening / closing mechanism.

**UPDATE: Looks like the MimoLite is no longer widely available. While not tested, appears this item should work: Zooz Z-Wave Long Range MultiRelay ZEN16 800LR for Garage Doors, Sprinklers, Gas Fireplace; 3 Dry Contact Relays (15A, 15A, 20A); 12-24 V AC/DC or USB C Power; Signal Repeater; Hub Required: Amazon.com: Tools & Home Improvement

Here’s a video (I haven’t watched it, but I’m sure it’s similar) https://www.youtube.com/watch?v=RPnY2Khukco

I also purchased some cheap alarm magnet sensors that I wired into the Mimo for the open/close (my gate wouldn’t tell me, so I used the mimo / these) Amazon.com : 1 : Electronics

I also created a custom switch that combines the cover and switch to open / close the gate.

- platform: template
  switches:
   front_drive_gate:
     friendly_name: "Front Driveway Gate"
     value_template: "{{ is_state('binary_sensor.front_gate_contact', 'on') }}"
     turn_on:
       service: switch.toggle
       data:
         entity_id: switch.front_gate
     turn_off:
       service: switch.toggle
       data:
         entity_id: switch.front_gate

Anyhow, hope it puts you on the right track.
