No Message from MotionSensor

[marcelkordek]

Hi, if my MotionSensor triggers MotionDetected I don't receive a message on topic homebridge/from/set. How can I fix this?

Thanks, Marcel

Hi cflurin, sorry here are the Details:

Versions

• Homebridge: 0.4.42
• Node: 8.11.2
• Homebridge-MQTT: 0.5.0
• OS: Raspbian GNU/Linux 9 (stretch)

Config

{"name":"Doorbell","service":"MotionSensor"}

Description

After my Doorbell rings, it send a message to homebridge/to/set -> {"name":"Doorbell","characteristic":"MotionDetected","value":true} to trigger the MotionDetected in Homekit. Every time my Doorbell rings I receive a notification from Homekit with an Image from my IP-Camera (same 'room').

But I don't receive a message at homebridge/from/set when my Doorbell rings.

I suppose the doorbell device sends the messages directly to homebridge-mqtt. Where are you expecting homebridge/from/set ? in your doorbell device or e.g. node-red?

Anyway the Characteristic.MotionDetected has only a READ perm (no WRITE), therefore there is no set function.

/**
 * Characteristic "Motion Detected"
 */

Characteristic.MotionDetected = function() {
  Characteristic.call(this, 'Motion Detected', '00000022-0000-1000-8000-0026BB765291');
  this.setProps({
    format: Characteristic.Formats.BOOL,
    perms: [Characteristic.Perms.READ, Characteristic.Perms.NOTIFY]
  });
  this.value = this.getDefaultValue();
};

That's correct my doorbell sends the message directly to homebridge-mqtt ->homebridge/to/set. I'm expecting this in node-red to trigger other actions outside from HomeKit.

For example:

• If I enter my HomeZone, set switch 'autoUnlock' for 10 Minutes to on (switch is added with homebridge-mqtt)
• If Doorbell rings, check if switch 'autoUnlock' is on
• If Doorbell rings and 'autoUnlock' is on, trigger the Doorlock (added with homebridge-mqtt) and set switch 'autoUnlock' to off

Ok, I understand. As a workaround I could have my Doorbell send two commands, one to homebridge/to/set and the other one to another topic.

Thanks, Marcel

I also use node-red, all my devices are connected to node-red using different protocols. When I need to send values to HomeKit I sends the messages from node-red.
