It’s worth it to delete the IR. Good luck.

I have a 2016 LG 70 in tv and followed this from the SimpleControl forum I copied it for you:
I couldn’t get my LG B6 (2016 model) to Power On/Wake on LAN, but the other day I finally cracked the code. It’s been working perfectly ever since. Note that my B6 is connected via ethernet, but I assume this would work over wi-fi as well. I had also given the B6 a static IP address in my router.
NETWORK > Wired Connection [Ethernet] (Click on this setting to see the B6’s MAC address, which you’ll need both to set up a static IP address and to do Wake on LAN in Simple Control.)
NETWORK > LG Connect Apps > ON
GENERAL > Mobile TV On > ON
GENERAL > Standby Light > ON (So that the red light on the front of the TV is illuminated when it’s in Standby mode.)
GENERAL > Quick Start+ > ON (So that when you power off the TV, it doesn’t actually power all the way off, but instead sits in Standby mode. From what I can tell, if this setting is off, the TV won’t respond to Wake on LAN.)
Here’s how I set up the LG B6 in Simple Control:
Add Device > LG TV (WebOS)
After you choose your initial settings, hit Save, then back out of the Edit menu completely.
Hit the Edit icon again, and go back in to the newly added LG TV and hit Test Remote. I’m pretty sure this is how I got the PIN screen to pop up on the TV for pairing. Enter the PIN in Simple Control.
Add or Edit an Activity, and in the list of Start commands, add a command for the LG TV, and choose +Wake On LAN.
The app then jumps back to the Edit Command screen. Here’s where you have to enter the B6’s MAC address (even though it says it’s only necessary for Manual IP devices). At first, I left out the MAC address, and it didn’t work. Just enter the letters/numbers in a single string with no colons. Save.
Edit the System Off activity, and add a Power Off command for the LG TV. Again, be sure to include the MAC address as above.
Customize your various Activity remotes as desired to include commands for the LG B6.
That’s it. Now the B6 always goes into Standby mode (and turns on its red standby light) instead of powering all the way off, and thus it’s receptive to the Wake on LAN command from Simple Control.
I’m not expert enough to know if this is the tidiest, most efficient way to do it, but this worked for me. And hopefully it’ll help anybody else who was as bummed as I was that the B6 wasn’t working with Simple Control.
