This guide will cover how to add a temperature/humidity sensor to Home Assistant using MQTT and Circuit Python. It is assumed that you already have a Home Assistant server up and running and that you have already installed the Mosquitto broker Add-on.
No soldering is required for this project, it’s plug-and-play thanks to the Metro ESP32-S2’s STEMMA QT port and the many QT-friendly sensors we’ve got. Simply plug in the sensor and run the code to make customizable projects with sensing and Home Assistant!
This guide shows you how to configure the SHTC3 Humidity and Temperature sensor for Home Assistant, though other sensors can be used with just a little modification. This particular sensor has a wide range of temperatures, excellent accuracy, has low power consumption and has a Stemma QT port for plug and play without soldering…
