Steps
Confirm the VSS path being written is typed as an actuator, since only actuator-type signals can be updated via VISS set/write
Connect to a running kuksa-databroker instance and use its actively developed kuksa.val.v2 protocol rather than the deprecated Target Value channel
Send the actuate/set request with the desired value for the actuator path
Treat a successful write response only as confirmation the request was accepted, not that physical actuation has completed or will succeed
Separately subscribe to the corresponding actual-value signal to confirm the actuator physically reached the requested state
Known gotchas
The older "Target Value" perspective for actuation is explicitly deprecated in favor of the "Actuation Value" channel — don't build new integrations against Target Value
A successful response from a VISS write only means the request was accepted by the databroker, not that the vehicle completed the actuation — a separate subscription is needed to confirm the real state
