CoIoT Library written in Golang

Package shelly-tools/coiot provides CoIoT (CoAP) communication with the popular Shelly IoT-Devices from Allterco Robotics. The CoIoT protocol is yet another protocol for IoT communication and integration. CoIoT is based on CoAP with some additions as new request code 0.30 for status publishing. All payloads are JSON encoded.

Installation

Install via $ go get github.com/shelly-tools/coiot.

Please add -u flag to update in the future.

Examples

A basic client example to query /cit/d path from the Shelly:

package main

import (
	"log"
	"os"

	"github.com/shelly-tools/coiot"
)

func main() {
	req := coiot.Message{
		Type:      coiot.Confirmable,
		Code:      coiot.GET,
		MessageID: 12,
		Payload:   []byte("Hello Shelly"),
	}
	req.SetPathString("/cit/d")
	c, err := coiot.Dial("udp", "192.168.178.212:5683")
	if err != nil {
		log.Fatalf("Error dialing: %v", err)
	}
	rv, err := c.Send(req)
	if err != nil {
		log.Fatalf("Error sending request: %v", err)
	}

	if rv != nil {
		log.Printf("Response payload: %s", rv.Payload)
	}
}
