Library to control G-Homa WiFi plugs
npm install g-homaNodeJS module to control G-Homa WiFi plugs. Functions include:
* Inclusion of new Plugs into an existing WiFi network without using the app.
Only works if the discovering device transmits via WiFi or
if the router is configured to forward UDP broadcasts over WiFi.
* Replacement of the default external C&C server with a local one, so the plugs don't have to phone home.
* Command line serial interface to manually talk to plugs on the local network.
Big thanks for the original work decoding the protocol!
ts
const gHoma = require("g-homa");const discovery = new gHoma.Discovery();
discovery
.on("inclusion finished", (devices) => {
// do something with included devices
})
.once("ready", () => {
// start inclusion
discovery.beginInclusion("psk");
})
;
`
You have to supply the WiFi key to the method. By default, inclusion stops after one device was found.
The overload beginInclusion("psk", false) keeps finding new plugs for 60s and then returns.
Discovery works by sending packets to the broadcast address of a network interface. If you have multiple ones, e.g. LAN and WiFi, you can select the one to use by providing options to the constructor:
`ts
const discovery = new gHoma.Discovery({
networkInterfaceIndex: 0,
});
`The devices object contains a table of IP and MAC addresses of the found plugs:
js
{
"ip#1": "AABBCCDDEEFF",
"ip#2": "FFEEDDCCBBAA",
// and so on...
}
`$3
ts
const manager = new gHoma.Manager();
manager
.once("ready", () => {
// find plugs (promise version)
manager.findAllPlugs(/ optional duration in ms /)
.then(plugs => {
// do something with the plugs
})
; // find plugs (async version)
const plugs = manager.findAllPlugs(/ optional duration in ms /);
// configure a plug to use the local C&C server
// async version:
let success / boolean / = manager.configurePlug("plug IP", "server IP", serverPort);
// restore a plug to use the default external C&C server
let success / boolean / = manager.restorePlug("plug IP");
})
;
`
Like with Discovery, you can select the network interface the Manager uses by providing options to the constructor:
ts
const manager = new gHoma.Manager({
networkInterfaceIndex: 0,
});
`$3
ts
const server = new gHoma.Server(/ optional port number /);
// ...
// close the server when you're done
server.close();
`The server emits a number of events:
-
: The server has been started. Parameters: address <{port, family, address}>.
- server closed: The server was shut down.
- plug added: A plug has connected to the server. Parameters: plugId .
- plug updated: A plug was switched. Parameters: plugInfo (see below).
- plug dead: The connection to a plug was lost. Parameters: plugId .
- plug alive: The connection to a plug was re-established. Parameters: plugId .The Plug object looks as follows:
`js
{
id: string, // ID of this plug
ip: string, // remote IP address
port: number, // remote port number
lastSeen: number, // last seen (UNIX time)
online: boolean, // if the plug is alive or dead
lastSwitchSource: "unknown" | "remote" | "local", // where the plug was last switched from
state: boolean, // if the plug is on or off
shortmac: string, // last 3 bytes of the MAC, e.g. DD:EE:FF
mac: string, // e.g. AA:BB:CC:DD:EE:FF
}
`$3
1. run it from the command line:
1. enter an ip address to talk to, or leave the line blank to broadcast to all plugs
1. enter password (default, can be changed)
1. if the plug responds, confirm the receipt with +ok
1. get a list of commands with (all commands need to include \r at the end)
