I needed something more versatile then the shell script that Weaved provides so I decided to write a python script and figured I would share it...
This will work with python2.7 and is mostly compatible with python3.x, you will just need to replace two raw_input() references with input(). I have tested this with Windows 10 and Putty 0.64 and on a Raspberry Pi 3 running raspbian.
For windows, it uses Putty to open a terminal window so the path to putty.exe will need to be set in the script. For linux or anything else it will use the 'ssh' command instead.
The Weaved username, password and device address can be hard-coded in the script or can be passed as options using the following syntax:
script.py -u weavedUsername -p weavedPassword -a deviceAddress
If the username and password have not been supplied the user will be prompted for input. If the device address has not been supplied it will display a list of devices along with their status, letting the user choose which to connect to.
Any feedback is appreciated.
Thanks!
