Forgive me if there is something obviously wrong here, I am new to Home Assistant. I added a homemade doorbell to my hassio configuration.yaml using
binary_sensor:
- platform: mqtt
state_topic: "doorbellsensor/status"
name: "Front Door"
device_class: occupancy
off_delay: 30
This gave me a binary_sensor.front_door which worked really well. I went on to add a second doorbell and changed to state topic to reflect which doorbell was pressed. My configuration.yaml now looks like this…
binary_sensor:
- platform: mqtt
state_topic: "doorbellsensor/status/front"
unique_id: db1
name: "Front Door"
device_class: occupancy
off_delay: 30
binary_sensor:
- platform: mqtt
state_topic: "doorbellsensor/status/back"
unique_id: db2
name: "Back Door"
device_class: occupancy
off_delay: 30
Unfortunately, after rebooting, the binary_sensor.front_door has disappeared but binary_sensor.back_door has appeared.
Reversing the order to the two entries in configuration.yaml brings back the binary_sensor.front_door but the binary_sensor.back_door is marked as unavailable. Is there something I am missing that is need to have two MQTT binary sensors?
