Running station manually when rain sensor is in bypass mode?

Can I run a station manually when a rain sensor is in bypass (rain) mode?

yes

Note

If the rain sensor is triggered, no schedules will run at their prescribed times. However, manual schedules (via the remote control) will run even if the rain sensor is triggered.

This assumes that the rain sensor is wired into the Rachio Sensor port and not in-line on the common wire (which will cause all watering to stop).
