Cannot switch channel (Samsung UE40ES6570)

Hi Together,

for my Samsung UE40ES6570, the SamsungTV binding works quite well, except switching channels. This has worked in previous openHAB2.5 but with my new setup (from scratch) on OH3.1, i cant switch the channel.

In the log, it mentions:

2021-11-14 22:25:14.579 [WARN ] [internal.service.MainTVServerService] - Samsung TV doesn't support transmitting for channel 'channel'

Setting the log level to TRACE, it gives the following ouput:

So it seems, as if this channel is ‘Read Only’. Is there anything i can do to enable switching channels?

Thanks in advance
