EDF Tempo: what's the colour of the day?
The live Tempo colour for today and tomorrow, plus what each colour means for your electricity bill.
Source: EDF, updated automatically Tempo is a regulated EDF electricity pricing option built around coloured days. Each calendar day is blue, white or red, and the price of your kWh depends on the colour, with cheaper off-peak hours every night (10pm to 6am). The idea is simple: electricity is much cheaper on the many blue days and more expensive on the rare red days, when the grid is under strain. If you can shift or reduce your usage on white and red days, Tempo can cut your bill significantly, which is exactly where home automation helps. Over a year, EDF spreads the days across three colours: The cheapest rate, and the vast majority of the year. Most of your consumption happens on blue days. An intermediate rate. More expensive than blue, but still moderate. Worth easing off on heavy appliances. The most expensive rate by far, only between 1 November and 31 March, on weekdays. During peak hours (6am-10pm) the kWh can cost several times the blue rate. Red days are the ones to anticipate. The rules are fixed: On a red day, the smart move is to pre-heat earlier, avoid running heavy appliances during peak hours, and lean on any battery or water tank you've already heated on cheaper days. Knowing the colour is one thing; acting on it automatically is where you actually save. Gladys Assistant retrieves the Tempo colour and lets you build scenes around it: lower the heating on red days, delay the water heater and the washing machine to off-peak hours, or get a notification the evening before a red day. It all runs locally on your own hardware, alongside your other devices. Combined with Enedis consumption tracking, you get a complete, private picture of what you spend and when. Cutting your electricity bill is a whole project: Track your consumption with Enedis and act on the data, locally and privately.

Each day under the EDF Tempo option is blue, white or red, and the colour sets the price of your electricity that day. Blue is the cheapest (about 300 days a year), white is intermediate (about 43 days), and red is the most expensive (about 22 days, only in winter). Today's and tomorrow's colours are shown live at the top of this page. Tomorrow's Tempo colour is published by EDF around 11am the day before. Before that, it isn't known yet. The widget at the top of this page shows tomorrow's colour as soon as it's available. There are at most 22 red days per year, and they can only fall between 1 November and 31 March, on weekdays (never weekends or public holidays). On a red day, peak-hour electricity (6am to 10pm) is far more expensive than usual. An EDF Tempo year has about 300 blue days, 43 white days and 22 red days, for a total of 365. The vast majority of the year is therefore at the cheapest blue rate. With a home automation platform like Gladys Assistant, you can retrieve the Tempo colour and build automations around it: reduce the heating on red days, shift the water heater and washing machine to off-peak hours, or get notified the evening before a red day. Gladys runs locally and is free and open-source. Gladys is free, open-source, and installs in a single Docker command.
