Logitech Harmony to MQTT Camera

[mpxd]

Install Fakeroku on Node-RED

Open the Node-RED Menu in the top right corner and click on Manage Palette. There switch to the Install tab and search for fakeroku and install the node-red-contrib-fakeroku.

Now add a Fakeroku node to your flow and configure it as follows:

The IP address has to be set to the LAN IP of your Node-RED installation - in my case 192.168.2.111, you can keep the default port and multicast IP and click the + icon to generate a UUID for your device.

Now switch to your Harmony smartphone app and search for new devices on your network. Fakeroku will show up as a Roku 3. Continue by adding an Activity and save your settings.

Set up Node-RED to Update MQTT Topics

The Fakeroku virtual device will now give you access to the following buttons on your Harmony Remote:

For example Button 1 will send the payload string Rev to Node-RED when you press it.

In the following I want to connect it to a Node-RED flow that allows me to cycle through the first 4 preset positions of my Pan&Tilt camera using the INSTAR MQTT Service when this button is pressed.

Here is the complete list of actions that the complete flow will add:

1. Rev - Go to last Preset Position
2. Play - Start a x Second Video Recording
3. Fwd - Go to next Preset Position
4. Home - Deactivate the Alarm
5. Up - Move Camera Up by one Step
6. Right - Move Camera Right by one Step
7. Down - Move Camera Down by one Step
8. Left - Move Camera Left by one Step
9. Select - Stop Camera Movement
10. Back - Activate the Alarm
11. Info - Trigger enabled Alarm Actions

The flow needed for those actions looks like this and can be downloaded and imported to Node-RED from the JSON export pasted in below:

Shouldn't you mention that one also needs to install the fakeroku node ?

[mpxd]

Oh absolutely right, it is the wrong link. I tried it with harmony-websocket before I used Fakeroku. I will change the link. Thank you!

You only need node-red-contrib-fakeroku
