trying with webOS 3.0 on lg 60sj8500, can't scan #7

Trying to figure out how the 'scan' works, and whether I have to edit lgtv.py or the .json file.

My LAN is 192.168.1.* and the TV is .118. I know its MAC by asking my router for it. What's the next step to having it scan? Should I just try nmap on the TV to figure out how different webOS is?

Line 92 - https://github.com/klattimer/LGWebOSRemote/blob/master/lgtv.py#L92

Here we send an "SSDP discover request" - this is a DLNA method for discovering devices, we then filter the devices down to LG TV's using a slightly inefficient try/except here

https://github.com/klattimer/LGWebOSRemote/blob/master/lgtv.py#L109

I'd say if anything your SSDP request is lost on your network, or the filter is broken.

Put response, address = sock.recvfrom(512) on line 108 and comment out the try/except block, then dump the response you get, paste that here and we'll go from there.

Please note that the IP range of the device isn't important, the SSDP discover will be received as a broadcast packet and responded to by any device that knows how. Also make sure that you're running WebOS 3+ (4 is fairly standard with everyone else now)

no response from OP, closing works for me.
