I have zway controller with MQTT client enabled and binary sensors which publish state to mqtt topic.

zway95/state/ZWayVDev_zway_9-0-48-12
off
or
on
Also I have such config in HA
binary_sensor:
- platform: mqtt
state_topic: "zway95/state/ZWayVDev_zway_9-0-48-12"
name: "testmotion"
device_class: "motion"
payload_on: "true"
payload_off: "false"
availability_template: "{{ value_json.metrics.isFailed }}"
availability:
- topic: "zway95/data/ZWayVDev_zway_9-0-48-12"
payload_available: false
payload_not_available: true
json_attributes_topic: "zway95/data/ZWayVDev_zway_9-0-48-12"
In HA sensor looks like unavailble and attributes are missing
Where did I make a mistake?
The way I understand the home assistant documentation availability_template is intended to be used along with availability_topic. So either go for
availability_template: "{{ value_json['metrics']['isFailed'] }}"
availability_topic: "zway95/data/ZWayVDev_zway_9-0-48-12"
payload_available: false
payload_not_available: true
or
availability:
- topic: "zway95/data/ZWayVDev_zway_9-0-48-12"
payload_available: false
payload_not_available: true
value_template: "{{ value_json['metrics']['isFailed'] }}"
