I don't think your TV uses the same protocol, it is nor a H nor a J model.

[cgarz]

Ah that's a pity. I missed that it was H/J specific. Would have been nice to have that lovely interface.
I managed to slap something together with inspiration from:
https://github.com/krzynio/python-samsung-smarttv-2016/blob/master/sstv2016.py

So now I can switch to Wii/HDMI and turn on/off by sending keys or sending a WoL packet.
I'll close this. Thanks anyway 😃
