Someone will probably make this better than I ever could, but I wan't to abandon Govee's API that uses their servers, since I don't like it.
An npm module to control Govee devices using their new LAN API.
Check Govee's WLAN Guide, they have a list.
UDP ports 4001, 4002 and 4003 are used on address 239.255.255.250. If you only allow certain IP addresses, also add the ip of your device directly.
Use these flag to allow for the correct ports to be accessed.
-p 4001:4001/udp -p 4002:4002/udp -p 4003:4003/udp
Also if you have a firewall inside of your container, make sure it allows requests going to remote port 4001 and 4003, and it allows requests comming in on local port 4002.
Here is an example of how to allow outgoing requests on port 4001 and 4003 (This is for Red Hat / Centos, check with the firewall on your distro)
sudo iptables -A INPUT -p udp --dport 4001 -j ACCEPT
sudo iptables -A INPUT -p udp --dport 4003 -j ACCEPT
For Node_RED examples, check the examples folder
const Govee = require("govee-lan-control");
var govee = new Govee.default();
govee.on("ready", () => {
console.log("Server/client is ready!");
});
govee.on("deviceAdded", (device) => {
console.log("New Device!", device.model);
});
setInterval(() => {
govee.devicesArray[0].actions.fadeColor({
time: 2000,
color: {
hex: Math.floor(Math.random() * 16777215).toString(16),
},
brightness: Math.random() * 100,
});
}, 2000);
var i = 0;
setInterval(() => {
i++;
// Loop back to 0 when at 360
i %= 360;
govee.devicesArray[0].actions.setColor({
hsl: [i, 100, 50],
});
}, 30);
