Using MQTT to inform your Smarthome that an Alarm was Triggered
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.
Make your camera the heart of your smart home
Using the MQTT interface of your INSTAR Full HD cameras you can connect them to an existing smarthome system (Home Assistant, OpenHAB, Node-RED, Athom Homey, Homematic, ioBroker, Loxone, homee) can be added. Or even make it the main broker for your MQTT sensors. MQTT allows you to automate ALL functions of your camera and link them to other services in your smarthome.
Control your camera via the IFTTT online service
On the IFTTT platform, we provided a service called INSTAR. The INSTAR applets provide you with the ability to control some settings of your INSTAR camera or INSTAR Cloud with IFTTT. You can connect INSTAR with triggers for location (Geo Location) and date & time, send notifications and much more. For example, you can connect INSTAR applets to the IFTTT location service and automatically disable the alarm when you arrive home. You can also use the INSTAR applets to create your own automation and connect them to other third-party applets.
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:
- Alarmbereich 1 ausgelöst:
1 - Alarmbereich 2 ausgelöst:
2 - Alarmbereich 3 ausgelöst:
3 - Alarmbereich 4 ausgelöst:
4 - Alarm-In / PIR ausgelöst:
5 - Audio Alarm ausgelöst:
6 - Bewegungserkennung & ausgelöst (Bereich 1):
7 - Bewegungserkennung & ausgelöst (Bereich 2):
8 - Bewegungserkennung & ausgelöst (Bereich 3):
9 - Bewegungserkennung & ausgelöst (Bereich 4):
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:
