Hello everyone! 
I’m thrilled to share my recent adventures in smart home automation. As a newbie, I’ve been diving into the world of ESP32 and Node-RED, and it’s been an incredible journey!
First off, I wanted to set up Bluetooth functionality in Home Assistant using an ESP32 as a proxy. I followed the YAML setup, but initially, I couldn’t get Bluetooth adapters to show up. After some research, I realized that I didn’t need a physical Bluetooth adapter plugged in—I could rely solely on the ESP32 acting as a proxy. That was a relief! Now, I can seamlessly integrate my Bluetooth devices without the hassle of extra hardware.
Next, I’ve been experimenting with Node-RED to create a fun and useful project. I wanted to monitor the charging status of my tablet and send notifications via Alexa. I set up a flow that checks the battery level and charging status every 15 minutes. If the tablet is fully charged or needs charging, Alexa sends a notification with a random voice—think of it as a smart home assistant with a personality!
Here’s how it works: Node-RED polls the tablet’s sensor data, checks the time to ensure notifications are sent only during waking hours, and then triggers a random voice response from Alexa. It’s been a great way to stay updated without constantly checking the tablet itself.
I’d love to hear your thoughts on these projects or any tips you might have for further enhancements. The community here is amazing, and I’m grateful for all the resources and support available!
Keep innovating, and let’s continue making our homes smarter together!
