Pool Comfort / Galaxywind pool heat pump — local Home Assistant integration

Hello, I reverse-engineered the Pool Comfort / Galaxywind (GWCD) Android app and built a local Home Assistant integration that talks directly to the heat pump over LAN UDP. No cloud, no vendor account needed.

GitHub: https://github.com/corekill/poolcomfort-galaxywind

What it does:
- Climate entity — set target temperature, switch between heat / cool / auto / off
- Sensors — water inlet temp, water outlet temp, serial number
- 100% local — all communication stays on your LAN (UDP port 1194)
- Install via HACS

Supported hardware:
Any pool heat pump that uses the "Pool Comfort" or "Galaxywind" app (com.gwcd.htc_en_oem). These are sold under many OEM brands — if your pump pairs with that app, it should work.

How to install:

  1. Add as custom repository in HACS
  2. Download & restart HA
  3. Add integration — enter pump IP and password (default: 123456)

If you have a compatible pump and want to try it, I'd appreciate any feedback — especially captures from different hardware variants. Protocol details are documented in the repo. reverse-engineered the Pool Comfort / Galaxywind (GWCD) Android app and built a local Home Assistant integration that talks directly to the heat pump over LAN UDP.
