Speedclimbing Stopwatch

Connects Companion directly to the itsblue.de speedclimbing stopwatch (ScStw) over its binary WebSocket API.

Setup

Connect the Companion computer to the stopwatch Ethernet network. The default address is 10.4.99.1; normally no configuration change is needed.

The Starter – 2×3 layout preset group is ordered for a Stream Deck Mini:

Lane A upper	Lane B upper
Lane A lower	Lane B lower
Secondary control	Primary / Ready

For an enabled lane, its display is on the upper row and its Disable/Fall control is on the lower row. When a lane is disabled, the two flip: Enable moves to the upper row and the read-only OFF display moves to the lower row. The action behavior flips with the labels, preventing an accidental press on OFF from enabling the lane.

The primary control and a lane's Fall command require two presses within three seconds, matching the confirmation behavior of the starter web interface. The starter primary control deliberately does not reset a finished race. Use the separate Reset race action on a custom button when reset control is wanted.

The connection uses ws://10.4.99.1/api/v1/ws with the required ws-v1.proto.scstw.itsblue.de subprotocol. Commands are never replayed after a reconnect.
