An BTHome v2 example. Make your DIY sensor, BTHome compatible Thanks @countrysideboy for his contributions on Encryption and cleanup code, the most of the code is from his side!
This is an example for a DIY BTHome v2 sensor.
The original code is from: https://github.com/TheDigital1/ESP32_BTHome
The header file contains human readable variables for the hex Object ids.
Sending entities to Home Assistant is simplified.
-
Download the files from Arduino Code folder.
-
Edit the BTHome.ino in your favourite Arduino IDE
-
Change the DEVICE_NAME to the one that should be recognised in BTHome integration
-
Change the BIND_KEY with your preference or remove it along with the
#define ENABLE_ENCRYPTfor no encryption -
Add the object id of the individual entities and the state of it as in the examples
-
Compile and upload to ESP32
DONE!
Read the comments in the code for more info. For the object ids consider using the variables from BTHome.h instead.
