- Expose IR commands for turning our bedroom fan on/off along with some battery-powered candles
- Flashed it to a Sonoff S31 to detect if our electric fireplace is on/off based on power usage.
- Secondary ESP32 that controls said fireplace with IR commands and has an attached dfplayer MP3 module to play a loop of fireplace sounds
- Wired up some photoresistors to an ESP32 that are spaced to match the status lights on our washing machine. The same ESP32 has an accelerometer attached to our dryer that changes its state depending on vibrations of the dryer.
- There's an ESP32 in our garage that has two VL53L0X time-of-flight range sensors to detect whether the garbage or recycling bin is out. In my automations I check if it's garbage or recycling day and send a notification if the bins haven't been taken out.
All of my automations are written in C#/.NET using NetDaemon.
