Followed setup instructions but input not changing

[jsaltzman]

I followed the setup instructions. I got the LG remote downloaded, the tv paired, and manually sending commands worked. I downloaded the provided script and edited to change HDMI input to correct input. Hammerspoon is running. But when I plugin my hdmi cable, nothing happens. Can you please help me troubleshoot? Is there a log I can look to?

[devantler]

If you open Hammerspoon it has a log :-)

It looks something like this depending on your OS:

[jsaltzman]

Here is the full log. Does this mean it is not loading the lgtv_init file?

my init.lua file has one line: require "lgtv_init"

Did you put lgtv_init.lua in ~/.hammerspoon. It should be the same location as the init.lua file?

If yes, try clicking "Reload Config" in the Hammerspoon UI

[jsaltzman]

Yes it is there, and I have reloaded the config a bunch.

[devantler]

Hmm if that is indeed in your home folder, I am not sure what is going on here. It should work like that. Maybe it can bring luck to try to reinstall Hammerspoon:

brew uninstall hammerspoon && brew install hammerspoon

EDIT: Oh wait. Did you enable debugging in the lgtv_init.lua script?

[jsaltzman]

I did not have debugging on, thanks.

I am still not getting the tv to turn on or switch HDMI when I plug in. I am going to paste my logs. At the end of the log I plug in HDMI and nothing happens. and throughout I was plugging in and unplugging HDMI to test the script.

Try to connect your TV to an HDMI port. Make sure the correct HDMI port and TV name is set in the script, and then start the script. Then the logs should guide you.

"I am still not getting the tv to turn on or switch HDMI when I plug in."

The script is not able to determine the HDMI port dynamically, and thus it cannot "switch" the HDMI when plugged in. The HDMI port and the TV name are hardcoded values in the script.

jsaltzman Thanks for logs. Explanation:

(1)

2023-09-12 20:11:20: Connected screens: { [1] = hs.screen: Built-in Retina Display (0x600002cfd138),[2] = hs.screen: LG TV SSCR2 (0x600002cfd178),}

Ok, your TV name looks like LG TV SSCR2

(2)

2023-09-12 20:33:22: No screens are connected. Please check the 'connected_tv_identifier' in the 'lgtv_init.lua' script matches your connected screen.

It looks like inside lgtv_init.lua file your 12 line does not contain this name. Check 12 line: local connected_tv_identifiers = {"LG TV", "LG TV SSCR2", "HDMI"}
