Sending commands to a Samsung TV via UART

It basically just lets you control the house TVs. It's a little nicer than IR, more stable, always works. I hardwire everything. I have a network rack in the middle of my house that everything goes to. This is the recent edition to it.

#

The EX-Link port of the TV plugs into a 3.5mm keystone wall jack, to 15m of Solid copper 4 core Station Wire, to a MAX232, to ESP32 PoE ESPHome module, mounted in a 42u rack.

Would be nice if there would be a way to read statuses from the TV. Eg. is it turned on or off. Or current volume level.

You can and it's in the YAML at the github link above.

I just have yet to do anything with it on the HA side any ideas?

Looks like this:

# Get Command:
# TV Reaction
# Success / Fail _F1_ _Success_
# Data Length    _8_
# Command        _F0_ _0_ _0_ _0_
# Data Value     _5_ _0_ _0_
# Category       _Power_
# Current State  _Normal Mode_

Get Power On
8 22 F0 0 0 0 E6

Return:
3 C F1 3 C F5 8 F0 0 0 0 F1 5 0 0

3 C F1 Command received (FF = fail)
3 C F5 Getting Data
8 Data Length
F0 0 0 0 Repeats back command you sent
F1 Success
5 Data output: Normal Mode
0 Dummy Data
0 Dummy Data

F1 Success
FF Fail
4 Stand-By
5 Normal Mode
8 Off

If the TV is fully powered off because of energy saving enabled then you can't get the off/standby information basically just assume off if no return or turn energy saving off. (You can still power the TV on though with it on)

#

Get Volume Return
3 C F1 3 C F5 8 F0 1 0 0 F1 C 0 0
C => Volume is at 12

With some ssieb assistance, we got get status parsing w00t. The full get stuff is in the GitHub Document now.

What about the QR-Codes on your labels?

potent stump What about the QR-Codes on your labels?

What would you like to know about them? You just scan them with your phone and they tell you where they terminate in the house

#

If you see on the wall jack there it basically has that information in it JA03-FL0-PA01-D30 so Wall JAck 3 - FLoor 0 (Main Floor) - PAtch Panel 1 in the rack - Data port 30 Then on the wire QR Codes say similar things JA03-FL0-PA01-V01 then adds devices they are connected to if specific purpose EX-Link 58 SamsungTV Port Etc. The QR Codes fit a lot of info on a small wire.
