Pontos

Home Assistant integration for Hansgrohe Pontos and SYR water meters (Trio, SafeTech+, SafeTech+ old firmware, NeoSoft). The integration talks to the local HTTP API of the device on port 5333 – no cloud, no account, everything stays in the local network.

This wiki documents the concept and the design of the integration for users who want to understand how it works and for developers who want to contribute.
