Why are short drives combined into one?

A drive ends once you've been parked for more than 10 minutes, so a stop for coffee doesn't split it in two.

With Roamer Plus, you can change that under Drive recording in Account → Preferences. Split after can be anything from 0 to 60 minutes, and at 0 every shift out of Park starts a new drive. Minimum drive leaves out drives shorter than the distance you set. Drives you've already taken stay as they were.

If your Rivian loses signal partway through a drive, in a tunnel or out of cell range, the drive stays in one piece unless the gap lasts more than 10 minutes. Miles driven during the gap aren't in any drive.

Why is a drive or charge missing?

Check these first:

Your Rivian account needs reconnecting. If you see Reconnect Your Rivian Account, reconnect it.
Roamer Plus was off. Drives and charges need Roamer Plus, and nothing was recorded while it was off.
Your drive recording settings. A short drive may be under your Minimum drive, or Split after may have joined it to the drive before.

If none of those fit, Rivian stopped sending data for a while. Your vehicle may have had no signal, Rivian may have had an outage, or several apps may have been reading your Rivian account and Rivian limited them. Linking Roamer through a secondary driver account helps with that last one. A gap can't be filled in afterward, except after a hard reset.

Still missing? Email support@rivianroamer.com with the vehicle, the date and the time. Don't unlink your Rivian account to fix it. Unlinking deletes your history.

What do I do when Roamer stops updating?

If your vehicle's gear, odometer or location stop changing in both Roamer and the Rivian app, Rivian has stopped updating them. Refreshing Roamer won't help, and no drives can be recorded until it clears. You'll get an email from Roamer if it notices.

The fix is a hard reset. Park, then hold the leftmost steering wheel button and the hazard button together for 5 seconds. The reset can take up to 15 minutes. Afterward, Rivian sends the readings it held back, and the missed drives show up at the times you took them.

Why does Mileage show more miles than my drives?

Mileage counts how far your odometer moved. Your drives add up only the miles Roamer recorded, so miles driven during a data gap are in Mileage but not in any drive.

Why is part of a route dashed?

There are no readings for that stretch. The dashed line runs straight from the last reading before the gap to the first one after it, so it isn't the road you took. Your vehicle may have had no signal, or Rivian may have stopped sending data. The stretch can't be filled in afterward.

Dashes past the end of a drive are miles on your odometer that aren't in any drive. On a trip, dashes can also join the end of one drive to the start of the next.

Where does top speed come from?

Top speed, average moving speed and the speed chart come from your vehicle's GPS.

Average moving speed leaves out the time you were stopped, at a light or in a parking lot, so it can be higher than distance divided by drive time. An imported drive keeps the other app's average, which counts time stopped.

While you navigate, Rivian also sends the navigation system's speed, and it sometimes reads double or more. A navigation speed is left out when the vehicle didn't cover the ground to match it, and so is any reading over 150 mph.

Why does a charge last overnight?

A charge is one plug-in. It runs from the first time your vehicle starts charging to the last time it stops before you unplug. Scheduled pauses and top-ups in between are part of the same charge, so a charge can span the whole night even if energy went in for only part of it. Plugging in without charging doesn't make a charge.

Why did my battery drop while charging?

On a slow charger, heating, cooling and the vehicle's other systems can use more power than the charger supplies, and the battery covers the difference. In the charge's energy breakdown on the web, that energy shows under Battery as a negative number. Energy delivered still counts everything that went in through the port, since that's what you pay for.

Which saved place is a drive or charge at?

The saved place whose radius it happened in. If two overlap, it's the smaller one.

A drive or charge is at Home only when it's inside your Home place's radius. The Home saved in your Rivian account doesn't count. If charges at home are showing up outside it, widen its radius or move it in Locations.

Is a charge DC fast or Level 2?

Rivian reports whether the charger supplied DC or AC. DC counts as DC fast, which some people call Level 3, and AC counts as Level 2, whatever the speed.

When a charge has no report, as with older charges, it counts as DC fast if it peaked above 20 kW and lasted under 3 hours. A Rivian draws under 12 kW on Level 2, so a Level 2 charge doesn't come close to that line.

Where do charger grades come from?

Rivian grades some charging sites from A to F, and Roamer shows that grade. Most sites don't have one. For networks other than the Rivian Adventure Network, the grade is an average of the network's DC fast sites.

How do Insights comparisons work?

Insights uses the same date ranges as Activity and counts the same drives and charges. "Vs last month" and the other comparisons are against the period before:

Today, this week, this month and this year are compared up to the same point. On the 25th, this month is compared with the 1st through the 25th of last month.
Last 7 days, last 30 days and custom ranges are compared with the same number of days just before them.
Since last charge and all history have no comparison.

Charge levels, phantom drain and Mileage come from daily records that run midnight to midnight Pacific time and can't be split. So Since last charge counts whole days. It can take in a few hours before the charge ended, or miss a few hours after it on the night it ended.

Why are times or days in the wrong time zone?

Your account's time zone decides where each day starts and ends. It starts out as Pacific, and you can change it under Time zone in Account → Preferences. The iPhone app keeps it matched to your phone. On the web, clock times, like when a drive started, show in your browser's time zone.

Charge levels, phantom drain and Mileage split days at midnight Pacific whatever time zone you've chosen.
