Programmed an ESP32 to listen via BLE for the Airthings Wave Plus and Wave Mini, sending stuff directly to MQTT now bypassing the Pi... the code is more stable than on the Pi (Bluetooth interface periodically malfunctioning and needs a reset). The way it scans for BLE devices is a little different than on the Pi so I need to do some more google-fu to find out how to support Wave 2 and Wave 1 devices.
These things are super fun to play with! Dev libraries are a bit different than standard Arduino so will need to figure out how to port rf69 code to the ESP32.
Also made a RF remote emulator for a ceiling fan. Used an RTLSDR dongle to pick out the exact frequency used by the remote, then used rpitx to record each button press, and wrote a python script to accept mqtt commands to trigger playback.
