Hi,
1st of all thanks for that great binding 
Everything works fine: channel and volume up/down, switching apps etc.
The only thing that I cannot get to work is to set the channel directly.
Number LG_TV0_ChannelNo “Channel [%d]” {channel=“lgwebos:WebOSTV:tv1:channel” }
I’ve tried:
LG_TV0_ChannelNo.sendCommand(2)
LG_TV0_ChannelNo.sendCommand('2')
The LG_TV0_ChannelNo is changed to the according value but the TV refuses to switch to that channel.
This is in the log:

When I switch channel by increase it works and I get this in the log:
