433 MHz is not dead! Using an ESP32 board with LoRa module to talk to 433 MHz sensors. Based on this and a youtube video from Andreas Spies I got one of these LoRa boards and set it up, it's kinda bonkers how much stuff it's captured in the last few days. From refrigerator temperature sensors, so some TPM (Tire Pressure Management) sensors (5 of them, so I guess one in the spare tire?)
