Tempo Card

Features

• Two cards: a full Tempo Card (custom:tempo-card) and a compact Tempo Mini Card (custom:tempo-mini-card)
• Color of today and tomorrow, with the date of each Tempo day (a Tempo day runs from 06:00 to 06:00); tomorrow shows Not yet known until RTE publishes it
• Animated scene: a pylon feeds a house under the sky of the period, the current flows faster as the day gets dearer, and a warning flashes on a red day at peak hours (see Animations)
• Current period (off-peak or peak hours) with its hours, a progress bar and a countdown to the next change, the current price per kWh and the price of the next period (with tomorrow's color when the next period starts the next Tempo day)
• Days left of each color in the season (1 September to 31 August: 22 red, 43 white, the rest blue), with bars
• Estimated cost of today and of the month, per color and period, from the long-term statistics of the six Tempo meter indexes and a price grid (EDF regulated prices by default, numbers or price entities), with an optional monthly subscription
• Header icon and status chip in the color of the day; the chip tells the current period
• Collapsible sections (period, season, cost): click a section title to fold or unfold it, a click elsewhere folds them back
• Detail button on the mini card (top right): it switches the mini card to the full card's content and back; a click anywhere outside the card brings the compact view back
• Click any value to open its Home Assistant history (more-info dialog)
• Visual editor in the dashboard UI for both cards (no YAML needed)
• Light and dark mode, English, French, German, Spanish, Serbian (Cyrillic and Latin), Italian, Dutch, European Portuguese, Polish, Romanian, Danish, Swedish, Bulgarian, Russian, Ukrainian, Hungarian, Slovak, Czech, Slovenian, Latvian and Greek
• Single file, no external dependency

Supported integrations

Integration	What the cards read
RTE Tempo (custom, rtetempo)	Color of today and tomorrow, days left of each color, off-peak flag and next off-peak change
Tarif EDF (custom, tarif_edf, Tempo contract)	Color of today and tomorrow (its calendar-day sensors, read as Tempo days: before 06:00, yesterday's and today's), Tempo prices of the six periods (used as the price grid)
EDF Tempo (custom, tempo)	Color of today and tomorrow and current period (attributes of its sensor)
Linky TIC (custom, linkytic)	Historic mode: the six Tempo indexes (BBRHCJB … BBRHPJR), current period (PTEC) and tomorrow's color (DEMAIN); standard mode: indexes EASF01-EASF06, the tariff label (LTARF) and the colors of today and tomorrow from the status register (STGE)
ZLinky_TIC in Zigbee2MQTT (mqtt)	Indexes current_tier1-6_summ_delivered, current period (active_register_tier_delivered / current_price) and tomorrow's color (tomorrow_color)
Any other entity	Set today_entity, tomorrow_entity, offpeak_entity, indexes, prices or days_left (templates, utility meters, other integrations…)

When several integrations provide the same information, the Tempo services come first (RTE Tempo, Tarif EDF, EDF Tempo), then the meter. The cost needs meter indexes recorded in the long-term statistics (energy sensors with a state_class, as all of the above are). Details in How it works.

Prerequisites

Home Assistant 2024.8 or later, with at least one of the supported integrations configured, or entities of your own giving the Tempo colors.

Configuration

Card types#

Visual editor#

Edit a dashboard, click Add card and search for Tempo Card or Tempo Mini Card. The entities found are used as they are; pick others if you wish, set the off-peak hours, the sections to display, the meter indexes, the price grid, the subscription and the language. The preview updates live, and options left at their default are kept out of the generated YAML.

Options reference#

Note

Check the default prices against your bill: they change a few times a year, and other suppliers sell Tempo-like offers at other prices.

How it works

The cards read the Home Assistant entity registry: every entity of a supported integration is recognized by its integration and its translation_key (Linky TIC), its entity id ending (Zigbee2MQTT) or its fixed name (RTE Tempo and Tarif EDF name their entities in French, without translation keys). Colors are read in every spelling these integrations use — Bleu, blanc, ROUGE, BLEU/BLAN/ROUG (DEMAIN), HCJB…HPJR (PTEC), HC BLEU (LTARF), Bleu HP, blue, 1-3 or the colored emoji — so an entity of your own (a template, say) works as long as its state is one of them.

Period and countdown#

The current period comes from offpeak_entity (or the integration's flag), otherwise from offpeak_hours. The bounds, the progress and the countdown come from offpeak_hours, in the time zone of Home Assistant; when the entity disagrees with them (other off-peak hours), the countdown follows the integration's own next change time if it has one (RTE Tempo), and is left out otherwise. The next period's price uses tomorrow's color when it starts with the next Tempo day (at 06:00).

Season#

A Tempo season runs from 1 September to 31 August with 22 red days (1 November to 31 March, weekdays), 43 white days and the rest blue (300, or 301 in a season with a 29 February). The days left come from RTE Tempo's Cycle Jours restants sensors (or days_left).

Cost estimation#

The energy of each index is read from the long-term statistics (recorder/statistics_during_period, daily change since the first day of the month), refreshed every five minutes: today's energy is the change since midnight, the month's the change since the first day. Each index is multiplied by the price of its color and period, and the monthly subscription (optional) is added to the month (its daily share to today). Index units in Wh or MWh are converted to kWh by Home Assistant. The result is an estimate: it uses the current prices for the whole month and leaves out taxes billed apart.

Features

• Tempo Card (custom:tempo-card): colors of today and tomorrow (animated), current off-peak / peak period with its hours, progress and countdown, current and next price per kWh, days left of each color in the season, and estimated cost of the day and of the month from the meter indexes and a configurable price grid (optional monthly subscription).
• Tempo Mini Card (custom:tempo-mini-card): today and tomorrow as two colored pills and the current period, with a detail button that switches to the full card's content and back (a click elsewhere brings the compact view back).
• Animated scene: a pylon feeds a house under the sky of the period (turning sun at peak hours, moon and twinkling stars off-peak), the current flows faster as the day gets dearer, a warning bolt flashes on a red day at peak hours; today's disc ripples (blue), shimmers (white) or pulses (red) and tomorrow's turns while its color is not published. Everything stops with prefers-reduced-motion.
• Entities found automatically from the entity registry: RTE Tempo, Tarif EDF, EDF Tempo, Linky TIC and a ZLinky_TIC in Zigbee2MQTT; every entity can also be set in the options.
• Estimated cost from the long-term statistics of the six Tempo indexes; default price grid of the EDF regulated Tempo prices of 1 August 2026, prices can be numbers or price entities.
• Collapsible sections (period, season, cost) folding back on a click elsewhere, visual editor for both cards, light and dark themes.
• 22 languages: English in the bundle, every other language in its own file loaded on demand.
