Investigating my Action WiFi enabled LED lamp
Status Initializing
Contact bertrik
Last Update 2019-11-03

Intro

This page is about a WiFi enabled LED lamp from the Action store, with E27 form factor.

I hoped this would be an ESP8266 based lamp, so it can possibly be flashed with my StofAnanas/stoflama firmware so it can indicate local air quality (PM10).

More info:

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

https://www.cleancss.com/mac-lookup/68-57-2D

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

Protocol

broadcast message

I sniffed the 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.

Capture

Turn ON

Turn ON the lamp: (captured with tcpdump -i wlan0 src 192.168.1.240 -X)
