Hey everyone! I wanted to share my recent experience with setting up map transformations in OpenHAB. I’ve been trying to get my heat pump to turn on and off using a map transformation, but it wasn’t working as expected. Let me walk you through my journey and hopefully help others who might be facing similar issues.
First, I created a map file named HPPower.map with the following content:
ON={“power”:“ON”}
OFF={“power”:“OFF”}
I linked this map to my heat pump’s switch channel in PaperUI, but when I tried to control it, nothing happened. The logs showed that the map transformation was being published, but the heat pump didn’t respond. I was a bit puzzled and decided to dig deeper.
After some research and testing, I realized that the outgoing value format needed to be correctly specified. Instead of leaving it empty, I set it to MAP:HPPower.map. This change made all the difference! The heat pump now responds perfectly to the mapped commands.
Here’s what I learned:
- Ensure your map file is correctly placed in the
conf/transformdirectory. - Double-check the syntax in both the map file and PaperUI configuration.
- Test each part of your setup incrementally to isolate any issues.
I’m really happy to have figured this out and would love to hear if anyone else has tips or tricks for working with map transformations. Happy automating everyone!
