You are doing fine, the problem at the moment is that there is no gas data, which ensures that the entities do not work for existing users and if you want to add the integration, it will not load further.
Iām still figuring out the best way to fix this.
Thanks. Probably create sort of a fallback to another gas data supplier; or set the value to 0.00 if there is no data available?
In the meanwhile i started up another HA instance on my raspberry pi and that seems to be a bit more rigid, with also the possibility for add-ons etc, also bluetooth etc. I think thatās the way to go for me.
Just to be sure: the prizes do not contain the ANWB inkoopkosten, taxes, vat?
If not: is there a way to configure an entity that contains the extra costs so the numbers presented are real prizes? (or just configure a number)
Only VAT is included, you should indeed add the rest yourself. This could be done, for example, by making a template sensor, I think there are some examples of this in this topic.
Right now the numbers that it produces do not mean anything to me if it doesnāt show real numbers. Therefore it would be great if the plugin gets a way to add taxes:
In the current situation I would have to create template sensors for nearly everything:
Future enhancement? 
Good addition, I had some ideas about that before.
However, it is not really the intention that an integration will adjust this internally, unless the API returns all the taxes on its own. As a result, you will eventually have to make some template sensors, we can think of something to make this as simple and less lines of code 
āin the options config_flowā: that would be perfect, allowing the entities to be used as-is without any templates or modifications.
I took a look at the code you shared but realized that Iām too unfamiliar with HA integrations to modify the code myself 
Unfortunately, that will never be approved in core, so you have to create those template sensors yourself.
Did you read this thread? What is the difference with your integration?
In Dutch:
I think iāve got it working now. A bit off topic: Now iām trying to see if my car will charge while the energy price is below 17 cents. Do you reckon this would work? Any advice for a HA noob?

Iāve got another one to stop charging when the price rises.
I have not seen it before, but the information about entso-e is known to me.
The main difference is that the integration for energyzero is made specifically for their API, in terms of entities you get the same as with ENTSO-e. However, the piece of visualization for the apexchart will be missing in core (but you can still add it as a custom component)
For me also a little bit off topic. But I have a tesla integration and there is a sensor to see the added energy. How can I make a counter to see the price for a total charge?
Because the counter for added energy increases over the hours, but when you have a dynamic price you canāt multiply the total charged x price because it will only uses the latest price then.
So how to create an hourly calculation and then a total calculation?
Thanks!
Hereās an idea that (without too much detail) could help you in the right direction:
In Google sheets perhaps?
Nice work, but if I use the sensor in my appex chart it only shows the price without the extra cost, is there a way to show the total price?
today I installed the energy zero integration and also created the sensors below because I use the ANWB.
- platform: template
sensors:
anwb_allin_current_energy_price:
unique_id: allin_energy_current_price
unit_of_measurement: "ā¬/kWh"
device_class: energy
value_template: >
{{ (states('sensor.energyzero_today_energy_current_hour_price') | float) + 0.17364 | round(4) }}
- platform: template
sensors:
anwb_allin_current_gas_price:
unique_id: allin_gas_current_price
unit_of_measurement: "ā¬/mĀ³"
device_class: energy
value_template: >
{{ (states('sensor.energyzero_today_gas_current_hour_price') | float) + 0.67541 | round(4) }}
Thanx for your work
How did you calculate the 0.17354 and 0.67541?
Energy tax 2023 electricity is 0,15245 (EB)
gas is 0,59266 (EB)
Or am I mistaken?

The difference in the costs is called the āinkoopkostenā.
Ah, yes! Thanks
