I wanted to be able to control my garage door from my phone so I created a custom BLE receiver for it with the RYBG211_Lite module from Reyax.
The receiver interacts with a NodeMCU board that then controls a relay once it receives the right message from the companion app that I made with MIT App Inventor.
You can check all the details in the video below!
The code for the NodeMCU and the App Inventor application can be found in the project repository.
