Integrating NeoHeat Heat Pump with OpenHab: A Comprehensive Guide

After installing my NeoHeat heat pump, I was determined to integrate it seamlessly into my OpenHab setup. The journey wasn’t without its challenges, but I’m thrilled to share my success story and some tips that might help others on a similar path.

The heat pump features a WLT-043R-NP00 front panel, which runs on Windows CE. Initially, I explored connecting it via a USR-W610 WiFi module, hoping to leverage MODBUS TCP or RTU. However, it became clear that the pump’s panel didn’t support MODBUS RTU, leaving me back at square one.

I then turned my attention to the USR-W600 and W610’s ability to act as a TCP server. While I had no prior experience with this, I dove into research and experimentation. The key was understanding the pump’s registers and how to communicate with them effectively. I discovered that while the pump could send real-time data to myheatpump.com, there was no direct API access, which was a setback.

After weeks of trial and error, I finally found a workaround using a custom binding and some clever scripting. The pump now integrates beautifully with OpenHab, allowing me to monitor and control it from a single interface. This integration has not only enhanced my home’s comfort but also simplified my daily routine.

For anyone tackling a similar project, my advice is to start small, document everything, and don’t hesitate to reach out to the community for support. Every challenge is an opportunity to learn, and the satisfaction of a successful integration is well worth the effort.
