How to use Cab mode

Cab mode is a single-purpose page for a cab, a vehicle or a site hut, with large buttons and no map, charts or time strip. It shows one large number for the wind at your working height, the lamp, and four rows of figures. It reads the last forecast the instrument at /app stored in this browser, so it shows the place, height, limit, unit and persona you last had there. It has no controls for any of them. Change them in /app, and Cab picks them up. It does not have the agent, a freeze button, the top bar or the left rail.

The banner reads LIVE with a time after a successful refresh, or CACHED with a time and not live when it is using the stored copy. The time is when the copy was saved, not the clock now. The status can add Offline, Refreshing or a refresh failed message with the reason. The lamp shows the same words as the instrument: GO, WATCH, STOP, UNKNOWN, or NO LIMIT when you have not set a limit. See lamps: GO, WATCH, STOP.

Now at height shows the modelled value for the current hour in your unit with the working height. It is a forecast, not a sensor reading. Next exceed hour is worked out from the ensemble and not from a single line. It shows the first hour from now when the share of members over your limit reaches 40%, in site time. If this hour is already at 40% or more it begins with NOW and gives the hour it first falls under 40%, or says none is in the window. P(>limit) is the share of members over your limit this hour, with received over expected members, or a dash and no ensemble. Your threshold shows your limit or not set. See read P(>limit).

The copy on your device holds the forecast, ensemble and nearest observation from the last time /app or Cab refreshed. If the device reports it is offline when you open Cab, you get CACHED and Offline with the saved time. Cab then shows the stored hour for the current time. The copy covers about a week from when it was saved, since a refresh from Cab fetches seven days. Once the current hour is past the end of the copy, Cab shows The cached forecast no longer covers this hour. with UNKNOWN and a prompt to refresh. Nothing there is current. The page does not refresh by itself on a timer, only when it opens and when you press Refresh.

There is nowhere on Cab to change them. Go to Full instrument, set the place, working height and limit, wait for the forecast to load, then return to /cab. The limit is only shown as it was last saved. If it reads not set, the rows that need a limit show dashes or a prompt. Cab does not follow a different persona unless you switched it in /app. If you freeze a record or save a rule, do it from /app.

If the number looks old, check the banner. CACHED means it is the stored copy. Press Refresh with signal. If it says refresh failed, the reason is shown, and the stored copy stays on screen. If the place is wrong, you last had a different place in the instrument, so open /app and change it. If the lamp reads UNKNOWN or the P(>limit) row has a dash, the ensemble did not load for this limit. See unknown and missing data.

It is not an observation and not an alarm. It shows modelled values, an ensemble share against your own limit and the same footer note as the instrument, that it is a modelled forecast and that probabilities are uncalibrated member fractions. Your limit comes from your own document and the decision is yours.
