MQTT Multisensor for Home Assistant

Create your own mqtt multisensor for HA just by configuring the values in the header file.

This code runs on my POE powered multi-sensors in my house. Each room has one header file, where the number and occurrence of sensors are configured.

Features

• SHT30 - Temperature, Humidity
• BH1750FVI - Luxmeter
• Termipol PM-1/2 - Waterflow
• Contact sensor - Door, Window, Motion, Water leak detection, etc.
• Relay - Switch
• Relay - Light

How to use it

Copy a header file (for example room_test1.h) and rename it according to your room name.

Comment out the defines that you do not need.

Change/add the sensor names, icons, pins in the corresponding variables.

Set your IP and MAC address.

Include your new header file in mqtt-multisensor-arduino-home-assistant-ethernet.ino
