I have a Samsung Smart TV and the M7 in the same room and they both come on. The M7 is opposite the Smart TV and therefore behind the remote control when I switch and it still comes on. I think this can also happen if both are in different rooms. Maybe someone knows if it is possible to set different channels on the devices and the remote controls?

I have two of these screens side by side. The remote controls work with IR and Bluetooth.

The Bluetooth connection is coded to the device, but the IR connection is not. This means that if the IR can see both devices, then they are both controlled.

I have therefore stuck the IR over and now the devices are controlled individually via Bluetooth.
