Hello,

I can not power off the TV from command line:

Code

I am using firmware v4(2012-12-06) and LE 7.0.3 (Generic.x86_64).

When I power off the LE it powe off the TV, so it is working well but I can not power off from command line.

Regards.

LibreELEC 7.0.3 is no longer being developed.

Alpha 7.90.010 and Beta 7.95.1 have libcec 4.1, you might want to try that.

You have to stop Kodi before you can use cec-client. Otherwise it's blocked. Alternatively you can use cec commands from within kodi, for instance python scripts or json.

Hello, thanks for the reply.

This is strange, because Amlogic CEC device works (with other problems), I can execute the cec-client while kodi is running

I will try to stop Kodi before execute it.

Regards.
