Node-RED and IFTTT

Q: I am currently working through the Tutorial on Node-RED and IFTTT.
Unfortunately, I'm stuck at the point: IFTTT - contact to a Node-RED endpoint. During the execution I get the error messages: "IFTTT Read error" and "SyntaxError: Unexpected token o in JSON at position 1" Unfortunately I am still an absolute beginner in Node-Red, but I hope that you can help me.

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: First start importing the following Node-RED sequence:

This has an Inject node to trigger an IFTTT webhook with the Event Name ifttt_webhook - which we have to create later in the IFTTT interface (the naming here is arbitrary):

INSTAR Camera Control with Node-RED and IFTTT

Don't forget to enter your IFTTT API key here, which you can look up in your IFTTT Account Settings.

In the following, we have created two webhooks in Node-RED - one for a POST and one for a GET request. You can decide later in the IFTTT configuration whether IFTTT uses POST or GET. We will test both here for now and decide later which one we want to use.

INSTAR Camera Control with Node-RED and IFTTT

The POST webhook has the URL /pushalarm/post/trigger/recording - that means if you want to call it on the local network, you would have to send a POST request to http://IP-der-Node-RED-Installation:1880/pushalarm/post/trigger/recording. This only works on the local network. For IFTTT you have to use a DDNS address - e.g. from an INSTAR IP camera in the same network - instead of the local IP address of Node-RED and an (external) port has to be forwarded to the internal port of your Node-RED installation:

INSTAR Camera Control with Node-RED and IFTTT

You can directly forward port 1880 here or select another port as the external port.

INSTAR Camera Control with Node-RED and IFTTT

The POST webhook has the URL /pushalarm/get/trigger/recording - that means if you want to call it on the local network, you can call this URL http://IP-der-Node-RED-Installation:1880/pushalarm/get/trigger/recording directly in your browser. You will get an empty JSON response {} here if everything is configured correctly.

INSTAR Camera Control with Node-RED and IFTTT

This empty response is generated in the HTTP Response Node named as Webhook. You can leave everything blank here.

INSTAR Camera Control with Node-RED and IFTTT

For the POST request, you must create the webhook in IFTTT as follows (the example uses the DDNS address of an AVM Fritzbox - an INSTAR DDNS address can also be used here). The port used here - separated from the DDNS address by a colon - must correspond to the port you have forwarded to the Node-RED installation in your router.

As you can see, we provide the JSON expression {"val": "on"} as the body here. We want to use this later to switch on the motion detection areas.

INSTAR Camera Control with Node-RED and IFTTT

For the GET request, simply select GET as the method and change the post to a get in the URL to be called.

INSTAR Camera Control with Node-RED and IFTTT

You can now test the IFTT webhook by going to the following URL https://maker.ifttt.com/trigger/ifttt_webhook/with/key/c3oL9WnAbz8Z08KumJWS. Here ifttt_webhook is the name we gave the webhook and c3oL9WnAbz8Z08KumJWS is your personal IFTTT API key (very important - do not share this key with anyone. It allows access to all webhooks you create in IFTTT).

INSTAR Camera Control with Node-RED and IFTTT

Alternatively, you can trigger the node-red-contrib-ifttt node in the Node-RED sequence to contact the webhook.

Now for something practical. Copy the following flow into your Node-RED installation:

This sequence gives you a new POST webhook on the URL /alarm/md/areas:

Sorts then whether a {"val": "on"} or {"val": "off"} was sent (we had set this in the IFTTT configuration):

In the following, the areas are then either switched on or off on the camera, which is set in the 8 Function Nodes:
