Plans and sensor limits

How many sensors your plan saves to your account, what happens when every slot is used, and which safety sensors are exempt.

In the app: /hubs/:hubId

Plans and sensor limits#

Your plan sets how many sensors RoamVitals saves to your account. A saved sensor has history you can chart, and it can alert you when you are away from the RV.

Sensors over that limit are not lost. They keep running on your hub, and you can still watch them live while you have the hub page open. They just are not recorded in your account.

What your plan includes#

Open Settings and look at the Subscription panel. It shows:

• Current Plan:, followed by a chip: FREE, PLUS, PRO or ENTERPRISE
• Hubs and Sensors (total), as usage bars
• Max Hubs, Max Sensors and Data Retention

The limits by plan are:

On ENTERPRISE the two usage bars are not shown at all, because there is nothing to fill up.

There is no way to change your plan from inside the app yet. On the Free plan the button under the panel reads Upgrade (Coming Soon) and cannot be clicked.

Saved or live only#

Open a hub from Hubs and look at any sensor card. Under the readings there is a switch with a chip next to it:

• Saved - this sensor uses one of your plan's slots, unless it is exempt (see below). Its readings are kept for your plan's retention window, they appear in its charts and in reports, and alerts on it can reach you when you are not in the RV.
• Live only - this sensor is not being recorded in your account. Its readings reach your screen while the hub page is open and are then gone, so there is no stored history and no chart for that time. The alerts you set up on it are listed as stopping too, and the app names each one before you decide.

Above the sensor cards you will see a line such as 3 of 5 saved sensors used. That count is for your whole account rather than for the hub you are looking at, so it is the same number on every hub page you open. When every slot is in use it reads 5 of 5 saved sensors used - to save another, stop saving one first.

A Live only chip can also appear next to a reading's timestamp. That marks a reading that is streaming right now and is not being written down.

Watching a live-only sensor#

You do not have to do anything to switch this on. When a hub has sensors that are not being saved, opening that hub's page asks the hub to stream them, and it stops as soon as you leave the page.

Live streaming is time limited, about 15 minutes per visit. If you leave the page open for a long stretch the live readings stop arriving. Reload the page to start them again.

When you reach the limit#

Three things change once every slot is used:

1. The switch on any Live only sensor is greyed out. Hovering it says: "Your plan's saved-sensor slots are all in use. Untrack another sensor to free one."
2. Add Sensor refuses. A message in red appears at the top of the dialog, for example: "Sensor limit reached for your subscription tier (5 sensors)."
3. New sensors your hub discovers on its own still show up on the hub page, but they arrive as Live only.

Nothing is deleted when you hit the limit, and nothing you already recorded is thrown away.

Choosing which sensors to save#

1. Open Hubs and select the hub.
2. Find a sensor you no longer need saved and switch it off.
3. Read the Stop saving [sensor name]? window. It lists, by name, every alert that will stop under These alerts will stop:.
4. Choose Stop saving it to go ahead, or Keep saving it to back out. Nothing changes until you choose.
5. Find the sensor you want instead and switch it on. The count above the cards updates.

The window also tells you what does not change: "Your hub keeps recording this sensor and will still sound its own alarms. What stops is the part that reaches you when you are not in the RV." and "Your existing history is kept and will age out normally. Nothing is deleted today."

If a sensor has no alerts on it, switching it off happens straight away with no window.

Deleting instead#

You can also free a slot by removing a sensor entirely.

1. Open the sensor from the hub page.
2. Choose the red bin icon at the top of the page, labelled Delete sensor.
3. The Delete [sensor name]? window says: "The sensor is removed from your dashboard and stops counting against your plan. Choose what happens to its recorded history:" and offers Remove data immediately, Keep data for 30 days, Keep data for 1 year and Keep data forever. Keep data for 30 days is already chosen for you, so that is what happens if you do not pick one.
4. Choose Delete Sensor to confirm, or Cancel to back out.

If you keep the history, that sensor is listed on the hub page under Deleted sensors with retained data, with a chip reading either purges and a date or kept forever, and a Purge now button next to it. Purge now asks once more, in a Purge [sensor name]? window that counts the readings it is about to destroy, and the button that goes ahead is Purge Permanently.

Sensors that are exempt#

A sensor carrying a safety alert does not use a slot, and it cannot be switched off from the sensor card.

An alert counts as a safety alert when it watches carbon monoxide, propane, smoke, a gas leak, or an alarm output. It is the alert that makes the sensor exempt, not the kind of device: a propane sensor with no propane alert set up on it uses an ordinary slot like anything else. The alert also has to be switched on. If you turn a safety alert off, the sensor stops being exempt and starts using a slot again.

Two things follow from that:

• If you try to switch a safety sensor off, the Stop saving [sensor name]? window opens with a red panel inside it: "This sensor has a safety alert on it." It names the alert, then says "This sensor does not count towards your plan and stays saved. If you really want to stop being told, remove the alert itself." The only button is Close. There is no way to override it from here.
• If you create a safety alert on a sensor that is currently Live only, that sensor is switched to Saved for you, even when every slot is already in use. Otherwise you would have an alert configured on a sensor whose readings never leave the RV.

Because exempt sensors do not use slots, you can have more sensors showing Saved than your plan's number. That is expected.

Example#

You are on the FREE plan, so you have 5 slots. Your hub has seven sensors, and the propane locker sensor has an alert called Propane detected on it.

The line above the cards reads 5 of 5 saved sensors used - to save another, stop saving one first, and the switch on Basement Temp is greyed out. Six sensors show Saved because the propane sensor is exempt.

To swap Bedroom Temp for Basement Temp:

1. Switch off Bedroom Temp.
2. The window Stop saving Bedroom Temp? lists Bedroom too cold under "These alerts will stop:".
3. Choose Stop saving it. The line now reads 4 of 5 saved sensors used.
4. Switch on Basement Temp. Its chip changes to Saved and the line returns to 5 of 5 saved sensors used.

Bedroom Temp keeps the history it already has, keeps recording on the hub, and shows a Live only chip from now on.

What to do if#

The Sensors (total) bar in Settings shows more than my limit. That bar counts every sensor on every hub in your list, which includes hubs other people have shared with you, sensors you are not saving, and sensors you deleted but chose to keep the history for. The number that matches your limit is the "of N saved sensors used" line on the hub page.

The line says 5 of 5 but I can count six sensors marked Saved. One of them has a safety alert on it. Those sensors always show Saved and are never counted against your plan.

The line does not match the sensors on the hub I am looking at. It is not meant to. It counts the saved sensors on every hub you own, so on a plan with more than one hub the number is larger than anything on the page in front of you.

The switch will not move. If you were given access to somebody else's hub rather than owning it, you cannot change what that hub saves. Only the hub's owner can. A short error, not_yours, appears under the switch, and if the Stop saving [sensor name]? window was open it stays open instead of closing. The saved-sensor count shown on that page is your own account's, not theirs.

A sensor I did not add appeared as Live only. Your hub found a device and told your account about it. Because every slot was in use, it arrived unsaved. Free a slot if you want it recorded.
