Build Your Own Multi Sensor with ESP32 and Home Assistant

#homelab #diy #homeassistant 🚀 Build Your Own Multi Sensor with ESP32 and Home Assistant The ESP32 is quickly becoming my favorite little microcontroller. And today I am going to walk you through building a multi sensor for Home Assistant that will monitor temperature, humidity, motion, and light all in one package. We are going to gather all the parts and pieces, wire it all together, then I will walk you through setting up the code in Home Assistant in order to get it to work with your install. 🖥️ Products and Links Project Materials - https://www.amazon.com/shop/hillphantom/list/1VY8J2T97NGXI?ref_=cm_sw_r_cp_ud_aipsflist_YYXG7ADAW939WX6F8XNW Installing Home Assistant - https://www.home-assistant.io/installation/ Installing ESPHome on Home Assistant - https://esphome.io/guides/getting_started_hassio Project Code (scroll to bottom of page) - https://makerworld.com/en/models/1052243-multi-sensor-case-30-38-pin#profileId-1039651 Project 3-D Printed Case - https://makerworld.com/en/models/1052243-multi-sensor-case-30-38-pin#profileId-1039651 💡One of the great things about Home Assistant is they teamed with ESPhome in order to provide an easy way to onboard your custom sensors. By using ESPhome builder, home assistant add on, we can quickly deploy our sensors on our networks and easily upload code. You can even upload firmware and code over the air via wifi once you have them deployed. 🗒️Chapters 00:00 - What are we building? 01:53 - ESP32 Pinout 02:53 - Parts List and Power 03:54 - Wiring Explanation 04:30 - Power Distribution 05:34 - Wiring it All Up 5:50 - Setting it up in Home Assistant 07:56 - The Code 09:10 - Flashing ESP32 10:06 - Installing it in ESPHome 11:09 - 3-D Printed Case 11:42 - Putting it all together 15:20 - Conclusion 🔋Once we get our ESP32 Multi Sensor installed into Home Assistant you can then start to use the values to set up automations or just simply to monitor on a dashboard. This multi sensor will give you temperature and humidity readouts, record motion, and has light sensor on it to tell if lights are on or off and even give you the intensity level of the light. This method will allow you to use less ESP32's and more sensor on one board. Heck you could even use more than three sensor as the ESP has plenty of GPIO pins. Just make sure you get the power distribution block in order to share the 3 Volt power connection and the ground with all the sensors. 📽️ My Other Home Lab Videos Discover my Top Home Lab Applications - https://youtu.be/yS72gNkpqok Learning Docker for Home Labs - https://youtu.be/RNlS4y-wfZs Virtual Machines for Homelabs - https://youtu.be/WjoiQgrFWXY How to Start a Home Lab - https://youtu.be/RqZSwEDXg_A Building Your Own Home Lab - https://youtu.be/y6ECUcVGg8o BUILD Your Own Cloud Storage - https://youtu.be/4hNcpdWEghQ I Chose UNRAID Over TrueNas - https://youtu.be/6V1qdiDoIL4 Discover my Top Home Lab Applications - https://youtu.be/yS72gNkpqok Basics of Home labs - https://youtu.be/y6ECUcVGg8o Raspberry Pi NVME Under Hat - https://youtu.be/jQRmBGEBkbg Raspberry Pi POE Hat - https://youtu.be/4mvGzSBd9Lg After this we have some fun, I print out a 3-D case for the ESP32 Multi Sensor for Home Assistant. Then we smash it all in the box and you will have a really awesome sensor set up for you Home Assistant instance. 🚨 Be sure to like, comment, and subscribe for more tech related videos.
