Lights after dark

Yarbo's lights come on by themselves while it works in the dark, on the schedule you set, and go off when it is done.

Where it lives: Yardstick Anywhere: Settings › Lights after dark Coming to the installed Yardstick in a later update.
The short version Turn on Lights after dark in Settings and pick when the lights should come on and go off. From then on, every job Yarbo runs in those hours has its lights on, from the moment it leaves the dock until it is back.
A few flashes as a job starts are normal For the first half minute or so of a job the lights may flash on and off. Yarbo switches its own lights off while it plans its route, and again as it starts to work. Yardstick turns them straight back on each time, and once Yarbo is working they stay on.

Turn it on

  1. Open Settings

    In Yardstick Anywhere, open Settings and find Lights after dark, just below Work Preferences.

  2. Pick the Yarbo

    With more than one Yarbo, choose it under Setting for. Each Yarbo has its own setting and its own times.

  3. Turn the switch on

    Yardstick also switches off Yarbo's Auto light mode, which would otherwise turn the lights off again during a job. If Yarbo is working right then, the change waits and the card offers to try again once Yarbo is idle.

  4. Choose your hours

    Lights on starts from sunset where Yarbo works, and Lights off from sunrise. Move either one up to six hours earlier or later. The card shows tonight's times. They follow the sun through the year, so the lights come on earlier as the days get shorter.

Every change is saved at once. Lights after dark works with every attachment.

When the lights are on, and when they go off

OnDURING YOUR HOURS
While a job is running: driving out from the dock, working, and driving home. Again each time Yarbo goes back out after charging in the middle of a job. If Yarbo is already out working when your hours start, the lights come on then.
OffSTRAIGHT AWAY
When Yarbo is back on its dock, on a fault, when your hours end, or when you turn Lights after dark off.
OffAFTER A SHORT WAIT
When Yarbo is paused, stuck or stranded, or a job ended early and left it sitting. Yardstick waits about half a minute first, so a pause on the way home does not blink them off.
Not on
Driving Yarbo by hand with no job running. Outside your hours.
On the charging pad While Yarbo is charging on its pad it ignores light commands, so the lights come on as it rolls off the pad, not before.

Your own Lights button

Press Lights in Yardstick during a job and Yardstick leaves the lights to you for the rest of that job. The next job is automatic again.

Yardstick cannot see a light you switch in the Yarbo app. Lights on during a job are treated as part of the job and go off when it ends.

Questions

The lights did not come on
  • Check that Lights after dark is on for that Yarbo, and that it is inside your hours (the card shows tonight's times).
  • A job has to be running. Driving Yarbo by hand does not turn them on.
  • Check the card says Yarbo's Auto light mode is off. If it could not be changed, press the button there when Yarbo is idle.
  • Give it a few seconds after Yarbo leaves the pad.
The lights flashed a few times as the job started

That is normal. Yarbo turns its own lights off while it plans its route and as it starts to work, and Yardstick turns them back on each time. They stay on once Yarbo is working.

Why did my Auto light mode change?

Yarbo's own Auto light mode turns the lights on and off by itself during a job, which would undo what Yardstick turns on. Turning Lights after dark on switches it off; turning Lights after dark off puts it back the way it was.

The lights stayed on at the dock

They should go off within about a minute of Yarbo settling on its dock. If they do not, email [email protected] with the time and we will look at what your Yarbo reported.
