Energieprijzen ophalen.lua

-- Instructions --
-- Create the dummy hardware in Domoticz if you haven't already and from there,
-- create two 'Custom Sensor' devices with the axis labels 'EUR/kWh' and 'EUR/m³'.
-- Then set the following two device ids:

@kipusoep I take it from my supplier, probably value of 2023 but excl VAT (BTW), and I just see it is merged with ODE

That explains @barts2108 😏
Btw, is your gas price still being updated? Mine hasn't since yesterday 1 AM and I see errors in the log.

Ah, it seems the energyzero api doesn't return any gas prices at the moment.

It would be great if the script can read the specific price for one supplier from the price feeds from Enever.nl (https://enever.nl/prijzenfeeds/) so everybody (from the Netherlands), no matter what supplier you have, can use your script. And you have the prices with and without taxes and all.
