Q: I found your guide to use the INSTAR (HTTP) Alarmserver. Wouldn't it make more sense to publish those events through the MQTT service that every Full HD cameras offers? This way I would be able to be sure that every alarm event is registered by my smarthome system.
A: All alarm events that published by the INSTAR HTTP Alarmserver can now also be accessed through the MQTT Service! The corresponding MQTT Topic is:
alarm/triggeredAll you need to do is adding a subscription to the Status Topic and you will receive updates about alarm events as well as what service triggered the alarm:
Appended Alarm Trigger
- Alarm Area 1 triggered:
1 - Alarm Area 2 triggered:
2 - Alarm Area 3 triggered:
3 - Alarm Area 4 triggered:
4 - Alarm-In / PIR triggered:
5 - Audio Alarm triggered:
6 - PIR & Area 1 triggered (coupled):
7 - PIR & Area 2 triggered (coupled):
8 - PIR & Area 3 triggered (coupled):
9 - PIR & Area 4 triggered (coupled):
10
In the following example I added the necessary subscription to a Node-RED Flow and translated the payload 1-10 to something more human-readable:
You can now continue with adding this output to your Node-RED Dashboard and continue with adding actions that Node-RED should trigger whenever a alarm trigger update arrives:
You can find the complete Node-RED Flow below, so you can import it into Node-RED:
