Multiple MQTT switches, one availability_topic

Configuration
,
1

Hello,

I am trying to set the availability_topic of many MQTT switches to the same value, so I can update that single topic with a Last Will Testament and get all MQTT switches disabled at the same time.

If I do this, only one of the switches is actually reading from the topic, the other just keep disabled forever, independently of the topic value.

Is what I want to do even possible?

If you need me to post any other information let me know.

Related configuration.yaml lines:

switch:
  - platform: mqtt
    unique_id: huerto
    name: "Huerto"
    state_topic: "/f0iehfw8dc2/SECTORS/huerto/SENSOR"
    command_topic: "/f0iehfw8dc2/SECTORS/huerto/ACTUATOR"
    availability_topic: "/f0iehfw8dc2/LWT"
    payload_not_available: "0"
    payload_available: "1"
    payload_on: "1"
    payload_off: "0"
    state_on: "1"
    state_off: "0"
    optimistic: false
    qos: 0

switch:
  - platform: mqtt
    unique_id: aspersores
    name: "Aspersores"
    state_topic: "/f0iehfw8dc2/SECTORS/aspersores/SENSOR"
    command_topic: "/f0iehfw8dc2/SECTORS/aspersores/ACTUATOR"
    availability_topic: "/f0iehfw8dc2/LWT"
    payload_not_available: "0"
    payload_available: "1"
    payload_on: "1"
    payload_off: "0"
    state_on: "1"
    state_off: "0"
    optimistic: false
    qos: 0

Remove the second switch: only one is allowed and all switches need to be under the same one.

All right, silly me, thanks!
