  We present an event-triggered boundary control scheme for hyperbolic systems.
The trigger condition is based on predictions of the state on determinate sets,
where the control input is only updated if the predictions deviate from the
reference by a given margin. Closed-loop stability and absence of Zeno
behaviour is established analytically. For the special case of linear systems,
the trigger condition can be expressed in closed-form as an $L_2$-scalar
product of kernels with the distributed state. The presented controller can
also be combined with existing observers to solve the event-triggered
output-feedback control problem. A numerical simulation demonstrates the
effectiveness of the proposed approach.
