Perhaps a noob question, but I tried your last code and added it to my configuration.yaml and restarted. It gives me the message: This entity is no longer being provided by the rest integration. If the entity is no longer in use, delete it in settings.
Any idea I’m doing something wrong with perhaps my dashboard?
See that I missed the sensor in the code, can you try this?

Thanks, yeah I did that but something went bad. Removed the lines, restarted, added them again and now it seems to work.
Thanks for the great code! Really useful since I moved to ANWB energy.
FYI, I’m currently working on an integration that will allow you to retrieve EnergyZero prices. The python package is almost ready and now mainly working on fixing the last bits in the integration (like how to handle tomorrow’s retrieval before 15:00).
That is awesome! This will also work for ANWB customers ofcourse, which is great 
Note that if you want to use “show extremas” feature, you have to change the data_generator.
Example:
type: custom:apexcharts-card
graph_span: 24h
span:
start: day
now:
show: true
label: Now
header:
show: true
title: Energyzero Electricity Price (€/kWh)
standard_format: true
yaxis:
- min: 0
decimals: 2
apex_config:
tickAmount: 8
labels:
show: true
title:
text: €/kWh
style:
fontSize: 12px
fontFamily: Arial
fontWeight: 500
series:
- entity: sensor.energyzero_electricity_price
float_precision: 3
stroke_width: 2
show:
in_header: true
extremas: true
type: column
opacity: 0.5
data_generator: |
return entity.attributes.Prices.map((record, index) => {
return [new Date(record.readingDate).getTime(), record.price];
});
The data generator now creates a date object.
In the series config the “show:” section is added to enable extremas (marking of the highest and lowest value)
Just wondering: inclBTW=true
Does that mean: including ODE and energiebelasting (2 extra taxes) and ANWBs margin (per kWh or m3)
Or should I manually add these?
When I read this, only the 9/21% VAT is added to the price, so you should add the rest yourself.
Klein foutje in de berekening? (eerste bedrag 0.019xxx ipv 0.109xxx)
Ik kom op € 0.09243
The cost work nice.
So how can I add the extra .09243 to the prize? For Electra and gas.
So I’m a bit stuck with the “how to add this to each attribute entry”.
Here’s how I calculated the extra cost for gas and electricity (as they are different)
# = Inkoopkosten + Energiebelast + ODE = SUM = incl 21% BTW
# electr 0.01908 + 0.04010 + 0.03325 = 0.09243 = 0.1118403
# gas 0.07455 + 0.39591 + 0.09429 = 0.56475 = 0.6833475
How are you progressing with the python package and the integration with HA?
Thanks,
Rien
I’ve already submitted this to the core repository for review, which is actually waiting for that. But in principle the integration is already usable.
And the python package can be found on PyPi, for those who want to work with code themselves:
Cool !!
So this will probably be in the 2023.1 release
Great work.
I don’t expect it to go that fast, it’s just how fast they get to it with the backlog of PRs. But you can already use/test the code as a custom integration (in custom_components folder) in Home Assistant.
What I was still thinking about is the possibility to enter the different additional costs (inkoop, energiebelasting en ODE) in the options config_flow, so that we can create an entity that shows your net costs.
hello Dirk,
I was stuck on the same thing, but I solved it.
As you can see I have added it to the value_template for each.

Hi, can you explain how to add the custom_component? i’ve copied energyzero folder from your github source into /root/config/custom_components, but that does not seem to work
Got it working, “version” is missing in manifest.json thats why it did not work, made one up…
Made some improvements and fixes for both the python package and the integration in the past 24 hours. Because a few things went wrong when the prices became 0 cents per kWh
