Hello everyone,

I’m sharing my setup to retrieve the TEMPO color (EDF option) in Node-RED.  
 ![node-red1](https://gladys-assistant-community.b-cdn.net/uploads/default/optimized/2X/b/b121fbcee3bad2e6037ec065cb66a7e134524933_2_690x34.png)

- The «&nbsp;Timestamp&nbsp;» node initiates a flow at 00:10
- The **function** «&nbsp;generateDate&nbsp;» node generates today’s date in the correct format (this will be the parameter of the http request:

```auto
const date = new Date();

let day = date.getDate();
let month = date.getMonth() + 1;
let year = date.getFullYear();

let currentDate = `${year}-${month}-${day}`;

msg.query = currentDate;
return msg;

```

- The **http request** «&nbsp;Couleur\_TEMPO&nbsp;» node performs the request with EDF’s REST API:

```auto
https://particulier.edf.fr/services/rest/referentiel/searchTempoStore?dateRelevant={{{query}}}

```

- The **function** «&nbsp;convert2msg&nbsp;» node extracts the useful info

```auto
var tempo=msg.payload.couleurJourJ;
msg.payload=tempo;
msg.topic="couleur_tempo";

if(tempo==="TEMPO_BLEU")
{
    node.status({ fill: "blue", shape: "ring", text: tempo });
}
if (tempo === "TEMPO_BLANC") {
    node.status({ fill: "white", shape: "ring", text: tempo });
}
if (tempo === "TEMPO_ROUGE") {
    node.status({ fill: "red", shape: "ring", text: tempo });
}

return msg;

```

At the output of the flow you get a result TEMPO\_BLEU, TEMPO\_BLANC or TEMPO\_ROUGE to use as you wish.

Just for my information, what is this EDF Tempo color? What is it for?

Without trying to be an EDF salesman or apologist, I quote:

> With the Tempo option, benefit from a favorable electricity price 343 days a year and greatly reduce your electricity consumption during 22 days of winter peak demand.

In short, if you need at least 9 kVA of usable power (this is the case for an older house heated electrically like mine) and you have a way to drastically lower your electricity consumption during the 22 RED days (decided the day before by EDF with the price tripled) — for example with a wood stove —
