#!/bin/bash

# dirty hack to make the MQTT messages sent by deye2mqtt.sh known to Home Assistant.
# Basically sends some MQTT messages to the Mosquitto broker that make Home Assistant auto-detect
# the information submitted by deye2mqtt.sh
#
# This will allow you to integrate your Deye Inverter's information into a Home Assistant installation
# via MQTT.
#
# Hacked together by Niels Ott <niels@drni.de>

# This program may blow up your cat.
