Since there is not LGTV plugin for Indigo, I have set up Homebridge, and have installed a plugin to handle communication to/from the TV, and a 2nd plugin that connects to the HomeKitLInk plugin in Indigo. From there, I have a "virtual" device in Indigo that when turned on or off, turns the TV on or off thru Homebridge. Probably not the most efficient way to handle this, but given my level of expertise(very little) I was able to get it to work. There was always some latency between the 2... maybe as much as 5 seconds... but now the latency gap has increased to almost 30 seconds, or more. Not the end of the world... but am curious if anyone else has a similar setup, and is experiencing the same issue. FWIW, turning the TV on/off directly from Homebridge is instantaneous, so the gap in time is between Indigo and the HomeKitLink Siri plugin, and Homebridge.
Not trying to point fingers... but just curious what might be causing this relatively new delay.
I have the latest version of HomeKitLInk. 0.6.5, and am up today with Homebridge and the plugs there as well.
