How does Yatse send the CEC Activate command to Kodi (from the Yatse power menu)? I would like to do something similar using Home Assistant so I looked through the JSON RPC API docs but couldn’t find anything. Is there an undocumented method I can call for this?
I could only find Kodi’s built-in function CECActivateSource that can be called from scripts.
That’s what I use there’s no JSON command. But for Kodi questions Kodi forum is the best place.
Thanks. I realize now that Yatse is using Kodi’s EventServer for the built-in actions. It’s not as clean as making a JSON RPC call but I can do what I want with the Python EventClient included in the Kodi source.
Well I tried for years to have JSON improved then gave up 
Event Server is still mandatory for a few things.
