F link jablotron
Home Assistant 0.94.0b3, 0.97.0, installed in docker at RPi 3 model B+ and RPi 4.State_topic: "backend/binary_sensor/jablotron_3/state" On the local host you need specify topics.On both hosts (local and remote) you need to setup an MQTT broker first of course. The command_topic will be used for receiving incoming states from a remote alarm_control_panel.The state_topic will be used for announcing new states (MQTT messages will be retained).You could specify which topics should be used. If the mqtt: component has been properly configured on the local host (directly connected to the Jablotron system), the alarm_control_panel will publish states and listen for changed alarm states automatically.
