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
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.
