My Luminus pricing (BE)

VinzzB · January 3, 2026, 8:44am

Just want to share one of my custom integrations.
This integration gets gas and electricity prices from My Luminus (Belgium). Only tested on fixed and variable rates.

Code and instructions: GitHub - VinzzB/my-luminus-pricing-ha-addon: Third-party addon for Home Assistant adds price information from active energy contracts.

Hi, was looking for something like this👍!
However, after install and entering log-in I get a “error connecting to api”.
Did restart twice and ctrl-F5.

Hmm, strange. I have it working for a few months now, and it also works after HA reboots. Your API responses from Luminus might (slightly) differ. I assume you can login at login.luminus.be without entering a recaptcha?

FYI Luminus has planned a maintenance window for tommorrow (11 jan).

Just looked at my code again and it is possible that i made a mistake in the coordinator class. I’m importing DOMAIN from homeassistant.core. At first glance this should’ve been imported from .const. I will look into it further as soon as i find some time.

I can login without entering a recaptcha.
Ok, I will wait and keep an eye at this thread.

I installed the integratin on a fresh HA installation (Core 2026.1.2) and i can login without any issue.

You might get more information about the exception by enabling debug logging mode in the integration.

I removed the integration, restarted, ctrl-F5 and installed it again.
From the log I get this:

ok, It looks like you’re logged in succesfully but the Luminus API is returning different information with your account. Do you have multiple meters (Gas, Electric, multiple ean numbers)?

Can you send me an anonymized response from the API call? Just use your browser, login to my luminus, then paste the url (https://www.luminus.be/myluminus/api/meter-readings/available-sources). You should see a JSON response wirth all your EAN meters.
