MQTT bridge for EWPE Smart powered devices

ewpe-smart-mqtt

MQTT bridge for EWPE Smart powered devices which can be controled via WiFi using EWPE Smart app

This project became possible thanks to great work of reverse engineering the original app protocol in gree-remote project

Prerequisites

Setup and run MQTT server (mosquitto is the easiest one)

Installation

1. Clone or download this repository

git clone https://github.com/stas-demydiuk/ewpe-smart-mqtt

2. Install dependencies

npm install

3. Make initial configuration by setting enviromental variables

Variable	Description	Default value
MQTT_SERVER	MQTT server URI	mqtt://127.0.0.1
MQTT_PORT	MQTT Server Port	1883
MQTT_USERNAME	MQTT Server Username
MQTT_PASSWORD	MQTT Server Password
MQTT_BASE_TOPIC	Base MQTT topic for bridge messages	ewpe-smart
NETWORK	Network adress (or addresses separated by semicolon) to scan devices	192.168.1.255
DEVICE_POLL_INTERVAL	Interval (ms) to poll device status	5000
LOG_LEVEL	App Log level	info

4. Run the bridge

npm start

Installation (Docker)

docker run -it \
    --network="host" \
    -e "MQTT_SERVER=mqtt://127.0.0.1" \
    -e "MQTT_BASE_TOPIC=ewpe-smart" \
    -e "NETWORK=192.168.1.255" \
    -e "DEVICE_POLL_INTERVAL=5000" \
    --name ewpe-smart-mqtt \
    demydiuk/ewpe-smart-mqtt:latest

Communicating with the bridge

• Publish to ewpe-smart/devices/list to receive list of registered devices
• Publish to ewpe-smart/{deviceId}/get to receive status of {deviceId}
• Publish to ewpe-smart/{deviceId}/set to set status of {deviceId}, payload should be json object with key/values pairs to set, i.e:

ewpe-smart/{deviceId}/set {"Pow": 1, "SetTem": 24}

Supported features depend on your AC unit, full list can be found here
