Tool to dump communication with tuya devices
This tool has been developped while coding a GO API to control Tuya devices (Available here)[https://github.com/py60800/tuya].
Despite being the result of quick and dirty coding, I found it great for debugging tuya communication.
Thanks to Erik Montnemery (@emontnemery), tuyadump now supports 3.3 protocol. If you encounter any issue, you can try the previous version (branch master).
Get the keys and ids of the tuya devices : https://github.com/codetheweb/tuyapi/blob/master/docs/SETUP.md
@codetheweb for reverse engineering tuya protocol
@google team for providing gopacket libraries
@emontnemery for providing clues and examples to support 3.3 protocol
and many others...
Install libpcap dev package (i.e. sudo apt install libpcap<version>dev)
Get gopacket library:
go get "github.com/google/gopacket"
Get this library
go get "github.com/py60800/tuyadump"
Build:
go build tuyadump.go comm-msg.go crypto.go dodump.godebug.go
Create a config file with the keys and id collected from tuya device (check example config for format)
To view traffic in real time
sudo ./tuyadump -C tuyaconfig.jsonport 6668
To view trafic collected with tcpdump:
tuyadump -C tuyaconfig.json -r dump.pcap
-d option can be used to dump packets as hex data
