Hello all,

I wired 2 shelly plus 1 devices to my 2 garage door openers. Using the Tasmota integration, I can control them both from home assistant. My issue is with the reed sensors and yaml. I use MQTT to see the status of the door and wrote this code that works-

binary_sensor:

name: “Gym Door State”

state_topic: “stat/Gym_door/status”

payload_on: “open”

payload_off: “closed”

availability_topic: “tele/Gym_door/LWT”

payload_available: “Online”

payload_not_available: “Offline”

qos: 1

device_class: opening

The issue is when I attempt to do the same thing for the second sensor i get the error “duplicate key”. This is probably a very easy fix, but if someone could please explain like I’m 5, id be very grateful
