This sketch is intended to be installed on Heltec LoRa32 board (V2 or V3). There's a chance it will work fine on the V1 board as well, but I haven't had a chance to test this setup.
The main goal of this sketch is to receive LoRa messages from connected nodes, translate them into MQTT messages and publish them to the MQTT broker. Communication between gateway and nodes is encrypted using the AES-128 algorithm.
All configuration parameters are located in the configuration.h file.
If you are interested in a case for this device, you can print it using this 3D model.
- Replace the
configuration.hfile with a website where the user will be able to configure the required gateway parameters.
This sketch is intended to be installed on Heltec LoRa3 V3 board. Theoretically, it can be installed on the V2 or even V1 board with some modifications in the configuration.h file, but I do not recommend doing this, because the door sensor is to be battery-powered and the V3 board has the lowest power consumption in this mode (V2 800uA, V3 <10uA).
An NO (normally open) or NC (normally closed) reed switch can be used. The switch type can be set in the configuration.h file.
If you are interested in a case for this device, you can print it using this 3D model.
- Add support for remote configuration
- Create an extended version of this device with a built-in alarm siren
