The CoIoT Protocol for Shelly devices
The CoIoT protocol is yet another protocol for IoT communication and integration. CoIoT is based on CoAP with some additions.
Every CoIoT device is expected to handle status and description requests and generate responses in
predefined format. Also every device is required to periodically send a multicast CoAP request with
its status

npm i coiot-coapconst { CoIoTServer, CoIoTClient } = require('coiot-coap');
// Listen to ALL messages in your network
const server = new CoIoTServer();
server.on('status', (status) => console.log(status));
await server.listen();
// Query devices directly
const client = new CoIoTClient({ host: '192.168.1.102' });
const status = await client.getStatus();
const description = await client.getDescription();
// or ...
const client = new CoIoTClient();
const status = await client.getStatus({ host: '192.168.1.102' });
const description = await client.getDescription({ host: '192.168.1.102' });$ ./bin/coiot
