Daikin WiFi Module Local REST API Documentation

Unofficial documentation for the Daikin BRP069C4x WiFi adapter local REST API, reverse-engineered from a live device and cross-referenced with the pydaikin library used by Home Assistant.

Tested Hardware

Property	Value
WiFi Module	4P359542-1H (BRP069C4x series)
Firmware	1_14_88
Model Code	0B66 (Type N)
Protocol Version	pv=2, cpv=2.00
Region	EU

⚠️ Firmware Warning: Firmware 2.8.0+ uses a completely different API (/dsiot/multireq with JSON). This documentation covers the classic REST API available on firmware versions below 2.8.0. Do not update your firmware if you rely on local API access — the new firmware may remove these endpoints.

Overview

The Daikin WiFi module exposes a local HTTP REST API on port 80 with no authentication required. All communication happens over plain HTTP on your LAN.

Protocol: HTTP GET requests
Response format: Comma-separated key=value pairs (e.g. ret=OK,pow=1,mode=3,...)
Authentication: None (LAN access only)
Discovery: UDP broadcast to port 30050 with payload DAIKIN_UDP/common/basic_info
Concurrency: ~4 simultaneous connections
Response time: 200–500ms typical

`aircon/set_control_info`

The main control endpoint. Uses HTTP GET with query parameters.

⚠️ All 6 mandatory parameters must be included in every request, even for values you are not changing. Always read current values first with get_control_info, then send them all back with your modifications.

Response: ret=OK on success, ret=PARAM NG on invalid parameters.
