Let's build a room sensor - Part 1 - Temperature, Humidity, and Bluetooth
Published at : 23 Dec 2025
I am aware of some glitches in the video, I was trying something new and apparently failed, please ignore it. In this video we will add the Bluetooth Proxy functionality to our Basic Setup as well as have a discussion around the Bluetooth Low Energy sensors, then add a DHT22 Temperature and Humidity sensor. You can find the bill of materials and code on my GitHub Page linked below. You will find the accompanying code on my GitHub Repo @ https://github.com/homeautomatorza/esphome/tree/main/Lets_build_a_room_sensor/Part%201
