Im not sure if i missed it in the thread but are you able to show the checksum calculation formula it appears to be a completely different formula from commercial grade screens.

Thanks,

I'm not sure how this will look on the forum, hopefully it shows up correctly:

=DEC2HEX(HEX2DEC(100)-HEX2DEC(RIGHT(DEC2HEX(HEX2DEC(MID(D4,1,2))+HEX2DEC(MID(E4,1,2))+HEX2DEC(MID(F4,1,2))+HEX2DEC(MID(G4,1,2))+HEX2DEC(MID(H4,1,2))+HEX2DEC(MID(I4,1,2))),2)))

I decided to share what I have that partially works to see if it helps anyone. Please feel free to contribute if you see something wrong! The script works great sometimes and after the TV power cycling it may or may not work. If it does work, it works for the entire time the TV is on.

Code is here (work in progress):

I'm able to turn ON the TV with both the Power-On and Toggle commands, but unable to turn it OFF. Neither Power-Off nor Toggle seem to work.

TV: UN60F8000
Power On: 8, 22, 0, 0, 0, 2, D4 (works)
Toggle: 8, 22, 0, 0, 0, 0, D6 (works as Power-On only)
Power Off: 8, 22, 0, 0, 0, 1, D5 (doesn't work)

Any ideas?

The link doesn't work for me. I'm trying to gain control of the Smarthub features on a TV.
