433 MHz is not dead! Using an ESP32 board with LoRa module to talk to 433 MHz sensors - CNX Software
Everyone is talking about Matter, Bluetooth, Zigbee, and Zwave, but before these complex communication technologies, we had one simple, robust one that our sensors and devices used to leverage: 433MHz. It may be too simplistic to talk about 433 MHz as a technology as there are different and various usages of this frequency. You can find it being used in numerous devices around your home, from your outdoor temperature sensors, and security sensors to the tire pressure sensors in your car.
