tplink-hs100

I wanted to figure out how to turn on or off my TP-Link HS100 Smart Plug. There doesnt seem to be any public API so I ran tcpdump on my tomato router while watching the commands sent from my phone to the device.

You'll probably need to change the IPADDR constant in the scripts but I dont think the port needs to change.

How I got the data

This might be useful to others, but if nothing else its my own notes of how to replicate my data:

1. SSH into the tomato router
2. Install the package manager ipkg from these directions: http://tomatousb.org/tut:optware-installation
3. Install tcpdump ipkg install tcpdump
4. Start capturing: /opt/sbin/tcpdump -w /mnt/sdb1/lighton-to-off-v2.tcpdump host 192.168.1.150
5. Copy file from /mnt/sdb1/*.tcpdump to my machine
6. Use wireshark to open *.tcpdump files.
7. Optional: use this filter on wireshark: tcp.flags.push == 1 to grab just the tcp packets. This might not be good if you want to inpsect the UDP broadcast packets.
