Remote Controls are used in the LEGO Train System since the introduction of the RC System. The have been used in different variants to control train motors and light on board of LEGO trains. Since the introduction of the LEGO Powered Up System, the Powered Up Remote Control is available, which connects via Bluetooth to Powered Up hubs.
Have a look at this video to get an impression:
Trains usually move fully automatically in the Mattzobricks Train Automation System. All switches and signals are also controlled automatically. Nevertheless, it is sometimes necessary to flip a switch or move a train manually over the layout – and it can be fun!
With firmware version 1.2, we have integrated the Powered Up Remote Control into the Mattzobricks Train Automation System. The remote is not connected to a Powered Up hub directly. Instead, the remote is connected via Bluetooth to a MattzoController called MTC4BT (MattzoTrainController for Bluetooth). The MattzoController accepts the commands of the remote, converts them to the Rocrail protocol and transmits them to the MQTT broker. The MQTT broker is broadcasting the commands to the MattzoTrainControllers, which in turn make the trains move in the desired direction, flip a switch or set a signal to green.

Where I can buy MattzoRemoteController?
Nowhere, but you can build one yourself as soon as we have developed and published it.
