Describe Your Problem

Thanks for all the work in this plugin - it's quite useful!

I started with issue #121 and was able to configure the plugin, which then found my monitor. Two icons popped up in my accessories list:

However, when I click on the screen, it does not toggle the screen state (ON/OFF). Moreover, when I click the volume button, it does not set the volume on the screen. The following errors appear in the plugin logs.

Am I doing something wrong? Thanks in advance!

It seems like there are multiple problems:

Regarding your volume issue: your TV must be turned on to control the volume. If it is turned on but you're still getting the same error message, you will have to re-register your device in your SmartThings App because they can't be controlled after some time if you are not using them.

Regarding the power issue: are you using the WoL functionality? If not please try to do so because some TVs can not be turned on using the SmartThings API

I hope this can help you with your problems. If it does not solve your problem please reopen the issue :)

Thanks @o-lukas I'll try your tips.

For info, if somebody gets here - re-registering the device did the trick for me. I can control it file w/o the WOL function. Both ON/OFF and volume work well.
