# LocalAC: local Gree air-conditioner control from protocol research

> LocalAC reconstructs local control of a Gree Pular T3 air conditioner through its LAN protocol. The author documents UDP port 7000 discovery, a bind handshake, AES-GCM command envelopes and property behavior measured on one firmware version. A C# protocol library supports a CLI and .NET MAUI app for status, temperature and other controls.

## Requirements & limits

- **Prerequisites:** .NET 10 and a Gree-protocol air conditioner on the same LAN are required.
- **Scope:** The documented hardware findings concern one Gree Pular T3 unit with firmware U-WB05RT13V1.45.
- **Limits:** Some reported properties are read-only or ignore writes on that unit.
- **License:** MIT license.
