TypeError: Unicode-objects must be encoded before hashing

I am getting this error.

So either the PIN or the timestamp are not in ascii. It looks like the PIN is good, so it must be the timestamp.

I'm just updating my TV to see if a later software revision has changed things.

The process still remains the same on QME164E.0.1.15.118 (19/1/2017) so it must be your environment.

I've not got a windows machine so I can't test this for you, but some logging of timestamp around line 47 will probably be useful to help diagnose

You are right, it was my environment. But can I ask you a question, do you know any guide or tutorial in translating a Python script to Groovy_

I want my Samsung Smartthings homeautomation controller torn off the TV when I am leaving my home.

Can you share as to what was wrong?

I'm not sure you need to translate the script. Which is why I've not that much with this project! The difficult bit is the pairing and then everything else is then just HTTP/JSON calls.

So, just use this bit of python to pair and extract the username and password that's needed.

Then in SmartThings you just need to make a digest auth HTTP request with the appropriate JSON payload.

So to hit standby you probably need to query the power state:

https://ip:1926/6/powerstate

Parse the JSON (I've not got an example at the moment) to determine whether it's currently on, and then send a standby remote command:

https://ip:1926/6/input/key

with a payload of:

 { "key" : "Standby" }

[denko81]

It was missmatching versions of Python and pycripto.

The problem is that both Python, Groovy and JSON are new for me as I learned Java in school and mostly used PHP.
