Remote Control

Remote Control (U-STATUS)

FlowStation can be controlled directly from a radio by sending TETRA status messages (U-STATUS). This lets authorized operators restart, shut down, or kick all terminals without touching the dashboard — useful when the BS is remote and you only have a radio in hand.

Configuration

[cell_info.sds_command_control]
authorized_issis = [2260570, 2260571]

[[cell_info.sds_command_control.commands]]
status_code = 32001
action = "restart"        # restart / shutdown / kick_all

[[cell_info.sds_command_control.commands]]
status_code = 32003
action = "kick_all"

How it works

1. A radio listed in authorized_issis sends a status message with a configured status_code
2. FlowStation matches it to a command and runs the action
3. Status messages from non-authorized ISSIs are ignored

Available actions

Action	Effect
restart	Restarts the BS service (uses the configured service_name)
shutdown	Stops the BS service
kick_all	Forces every registered terminal to re-register

Security notes

• Only ISSIs in authorized_issis can trigger commands — keep this list tight
• Pick status_code values that won't collide with normal status traffic on your network
• restart/shutdown rely on the service name matching your systemd unit (see Installation)
