Schedule widget

A timeline of upcoming periods — tariff prices, delivery windows, shifts — with the period happening now highlighted.

Coming in app version 1.6

This section describes a feature in an app update that's pending App Store review. It unlocks here automatically once the update is live.

Fields

Field	Type	Notes
`template`	string	Required. Must be `"schedule"`
`periods`	object[]	Required. Between 1 and 48 periods (two days of hourly data), in strictly increasing `start` order. Replaced wholesale on PATCH — re-send the whole window you want drawn (typically today plus tomorrow), never append period by period (why)
`periods[].start`	string	Required. RFC 3339 timestamp the period begins. Must be strictly after the previous period's start, after 2000-01-01, and no more than 366 days ahead
`periods[].value`	float	Required. The value for that period — price, load, headcount. Must be finite. Unit-agnostic; label it with the content-level `unit`
`periods[].level`	string	`low` / `medium` / `high`. Sets the band color for that bar. Absent means the client derives bands from the posted range
`unit`	string	Unit or currency symbol rendered with the values (e.g. `"¢"`, `"kW"`). Max 32 characters
`label`, `subtitle`, `icon`, `accent_color`, `background_color`, `text_color`	string	Shared content fields — see the API reference

Behavior

A period runs until the next period's start; the last one has no successor, so it extends to the edge of the chart. The widget finds the period containing the current time and highlights it, re-evaluating on device as the clock moves, so an hourly tariff needs one push per publish rather than one per hour.

level is optional per period. When you omit it everywhere, the widget splits the posted range into terciles and colors each bar by which third its value falls in. Set it explicitly when the bands mean something specific (a supplier's own off-peak / peak definition, a staffing threshold). Mixing the two within one payload is allowed but reads inconsistently, so prefer all or nothing.
