Integrating Garmin MyHomeControl with OpenHAB: A Technical Challenge

General
1

I recently decided to explore the integration of my Garmin MyHomeControl app with OpenHAB, aiming to streamline my smart home setup. While the concept sounds straightforward, I’ve encountered a few hurdles that I’d like to share and seek advice on.

The Goal:
I want to use the Garmin MyHomeControl app to trigger OpenHAB REST APIs via myopenhab.org. This would allow me to control my smart home devices directly from the MyHomeControl interface, adding a layer of convenience to my daily routine.

The Setup:
I’ve successfully tested my API endpoints using Postman, which means the OpenHAB side is functioning correctly. However, translating this into MyHomeControl has proven tricky. The documentation mentions defining URLs without HTTP prefixes and using specific encoding for special characters like &, %, and spaces. For example, 192.168.2.1/sw/23_and_command=on is the recommended format.

The Challenges:

  1. JSON Body Handling: The MyHomeControl documentation provides examples of using jspost for JSON bodies, but I’m unclear on how to structure this for OpenHAB, which expects raw text commands. For instance, how do I translate jspost={value1:morning,value2:11.00} into a format OpenHAB understands?
  2. Basic Authentication: I’m also struggling with implementing basic authentication within this setup. The documentation doesn’t provide clear guidance on how to include authentication headers or tokens in the URL structure.

Seeking Solutions:
Has anyone successfully integrated Garmin MyHomeControl with OpenHAB? Any insights or workarounds for handling JSON bodies and authentication would be greatly appreciated. I’m particularly interested in understanding if there are alternative methods or scripts that could bridge this gap.

Conclusion:
While the integration presents some technical challenges, I’m optimistic that with the right approach, it can be achieved. I’m looking forward to hearing from the community—your experiences, tips, and tricks would be invaluable in overcoming these hurdles. Let’s collaborate to make this integration a reality!
