TV: Can't load sources

[y0m1g]

Hello, I'm unable to have the TV channels from the tuner appear in the inputs of my Sony X90J in the HomeKit app. I've tried tv:dvbt, tv:dvbc or tv:dvbs, in both normal and external modes, and nothing works.

I've enabled debug logging in Homebridge for this plugin, and here are some errors that seem related:

TV is up to date too. Thank you

No idea, you'd have to find out what the correct names are for that TV. It seems to me that in general the command didn't fail, just looking for the wrong name. If you can't find out the correct name from the interwebs, the wiki might contain some commands to get the TV to send some info about itself via HTTP.

For those who might come here later, here's how I've solved this issue: did curl -v -XPOST http://{IP_OF_MY_TV}/sony/avContent -d '{"id":13,"method":"getSourceList","version":"1.0","params":[{"scheme":"tv"}]}' after taking a look at this wiki page as @normen suggested, and got 2 results: tv:analog and tv:atsct. tv:atsct worked for me (I'm in Canada)!
