Intro

This page is about a WiFi enabled LED lamp from the Action store.

https://www.action.com/nl-nl/p/lsc-smart-connect-slimme-multicolor-ledlamp-3/

Hardware info

The lamp communicates over 2.4 GHz WiFi.

It has two setup modes, triggered by switching it off-and-on three times quickly in a row

  • fast blink mode: about 1 blink per second
  • slow blink mode: about 1 blink per 3 seconds

MAC address: 68:57:2d:1a:6a:ea

It received ip address 192.168.1.240 through DHCP from an OpenWRT router.

Protocol

broadcast message

I sniffed to protocol using TCP dump.

Changing the state of the lamp by the app causes a message to be sent to (TCP): ec2-3-121-210-75.eu-central-1.compute.amazonaws.com.8886

The local protocol appears to use UDP. There is an UDP broadcast message sent by the lamp of 172 bytes.
