#Garage Door Opener and Environmental Sensors

I used a ratgdo shield to connect my garage door to Home Assistant and to collect a lot of environmental data. Unlike many of the amazing projects shared here, I used off-the-shelf components mounted to an Adafruit Swirly grid. There was minimal soldering at all with the project! These components are SparkFun Qwiic and Adafruit Stemma I2C modules. I used an LTC4311 chip to allow a long wire (using an RJ11 phone cord) to position the I2C sensors on the garage ceiling in an ideal location. An ultrasonic distance and template sensors determine if the car is in the garage. The motion sensor turns the lights on and off automatically. Finally, temperature, humidity, and pressure data are all collected.

This is a good showcase of several components that I implemented for the ESPHome project: Zio Ultrasonic, BMP581, and Qwiic PIR (that PR has not been accepted yet). If you want to read more details about this project, I made a post on my personal website with much more detail, links, pictures, and example configurations: https://www.kevinahrendt.com/garage-sensors (if this is too much self-promotion, please let me know so I can remove the link.) I can also add more information here if anyone is interested!

The link is fine. That's what this section is about.

Good to know, thanks

neat, i'm planning on doing a more limited build with one of the ultrasonic sensors to detect if the door is open or closed, potentially expanding to see if cars are parked there too

Depending on the dimensions of your garage, you should be able to fairly easily. If the distance is very small, then the door is up. If it is a medium distance, the car is in the garage, and a large distance is door closed an no car.

That was my original plan when I bought the sensor a year ago! The ratgdo shield/component takes care of it all though, so I guess I am fortunate I have that type of opener.

Great idea! I think I am going to add that to my tilt sensor for the Garage door! I will have to document my opener once I switch it over to ESPHome. Currently I have it with zwave Zooz Universal Relay and it works but why not really control the door via ESPHome. BTW was able to control the door by wiring directly into the controller see pic below

Nice! I did something basic with just the opener, cool to see more ideas here.
