API SDK: Wake-on-LAN via Gladys core

[spenceur]

Context

External integrations are executed in an isolated Docker container. They can send a unicast Wake-on-LAN packet, but they cannot broadcast a packet on the local network.

Problem

Some devices (in my case an LG webOS TV) no longer respond to unicast Wake-on-LAN after prolonged sleep, likely due to the expiration of the ARP entry.

Wake-on-LAN works perfectly in broadcast (`192.168.1.255`), but this broadcast cannot be sent from an external integration.

Proposal

Add an API in the SDK to request that the Gladys core send a Wake-on-LAN packet.

Example:

await gladys.network.wake({

  mac: '64:e4:a5:b4:88:74',

  address: '192.168.1.255', // optional

  port: 9,                  // optional

  sourcePort: 9,            // optional

});

Since the Gladys core is running in `network=host`, it can send the broadcast on the local network without the container’s limitations.

Use Cases

• TV (LG webOS, Samsung, …)

• PC / NAS

• Servers

• Any integration requiring reliable Wake-on-LAN
