Obtaining API token from Entso-E
EDIT 2024
We have since this article was written implemented an intermediate server that performs the "heavy lifting" of reading prices from the Entso-E API. We have there also implemented some backup mechanisms in case the Entso-E API does not respond (which we have seen from time to time).
We therefore no longer recommend reading directly from the Entso-E, but in stead do the following: Activate "Enable price fetch from remote server" in the configuration but leave the next field blank. Your device will then read from our intermediate server:
(We keep the content of the rest of this article in case anyone uses it as reference.)
Pow-K+ and the newest version Pow-U equipped with ESP32 microcontroller can read and display hourly energy prices.
The data source is the non-commercial EU-financed page https://transparency.entsoe.eu/
You can register and obtain API token free of charge, and here is the procedure:
- Go to https://transparency.entsoe.eu/ and click "Login" in upper right corner.
- A new window opens, click on "Register" at the bottom. Fill in your email and select a password, which must be at least 14 character long and must contain at least one special character (other than letter, digit or '@').
- You'll receive an email requesting you to confirm activation. Click the link in the email, and you're logged in.
- So far so good - normal stuff.
Now you need to send them an email to request API token, that information is somewhat hidden in paragraph 2 on this page:
Send an email to transparency@entsoe.eu with “Restful API access” in the subject line. Indicate the email address you entered during registration in the email body. The ENTSO-E Helpdesk will make their best efforts to respond to your request within 3 working days. - They will normally respond next working day, I guess 3 days is to be on the safe side.
When you receive answer from them, there will be a button on your "My account settings" page. Click it to generate API token.
Open the main page of your Pow device, go to Configuration / ENTSO-E API, copy in your API token. Select your price region (see below map, contact your electricity company if in doubt).
Note that there is a multiplicator on this config page which you can use to simulate/approximate VAT and other taxes added to the system price.
Voilá!
