Zhonghong MQTT

An integration for Zhonghong thermostat gateway and MQTT brokers, in order to control thermostats with Home Assistant, running with Docker.

Overview

The gateway supports many interfaces and protocols, such as Zigbee, TCP, HTTP and RS485.

For efficiency, we use the HTTP API temporarily.

Such as TP-LINK TL-WR800N.
