After configuring the integration no entities are made, and an error comes up saying the configuration failed. The log file says the following:

I fixed this by adding the DEFAULT_CONSUMPTION_USE_OTHER constant to const.py:

DEFAULT_HEATPUMP = False
**DEFAULT_CONSUMPTION_USE_OTHER = 0**

And added the import in init.py:

CONF_STARTMONTH, CONF_WEATHER_STATION,
DEFAULT_CONSUMPTION_SENSOR, DEFAULT_DHW_CONSUMPTION, **DEFAULT_CONSUMPTION_USE_OTHER,**
DEFAULT_HEATING_LIMIT, DEFAULT_HEATPUMP,

Could you give us /me :-) examples to copy how this integration works? I installed it using HACS this worked, but no sensors where made? I know, I shouls probelbly know how to. but I did not chose a UI system for the fun off it. I like things going by itself? or other people making it easy for me ;-). I am not a coder.

Copied from #17 by @bakboord4

Noticed that the prognosed gas consumption shows about 60% what the dutch mindergas.nl website is prognosing.
I have to find out how your integration is working.
It would be helpful to me what is meant with 'year'. May I suggest to make in the documentation and in the sensor names everywhere explicit: calendar year (starting 1 jan) or billing year (date of year-gas-consumption is measured).
Especialy for prognosed gas consumption. Is this for the whole billing year or to 'year to date' (today)?
Thanks in advance for your reaction.

This is the exception from the Hassio Logs

in Belgium we use other stations... or give the option select your your own station in home assistant ie darksky etc

As you mention in the readme, a Gas sensor entity with the total consumption this year should be feeded to the integration.

Is this a sensor of the last 365 days? Or a sensor from the 1st of january? What is needed by the integration?

If I may make a suggestion for 'product improvement':

Create an option to use the results of a kWh meter instead of the gas meter for consumers of a heat pump.

Hi Ernst, leuk idee dit, hoop dat je integratie blijft werken en super dat je hem al zo hebt opgezet dat hij al in HACS past! Volgende stap natuurlijk dat hij niet meer custom hoeft te worden toegevoegd, maar automatisch in HACS komt én dat je dan ook een icoontje toevoegt :) Zie dat je er nu nog geen een hebt, in de lijst van HACS komt er daarom alleen een "image not available" bij de verwijzing (https://brands.home-assistant.io/_/degree_days/dark_icon.png) en daardoor zie je in bijvoorbeeld het repairs scherm niet waar het over gaat:

Voor meer info over hoe je je eigen icoon toevoegt, zie https://github.com/home-assistant/brands/tree/master/custom_integrations/

Thx man, ik ga er binnenkort eens mee stoeien!

how can I compensate for the initial gas meter reading on Jan 1st? I think it just uses the meter reading.
I do not have a sensor for consumption only a gas meter reading since installation of the gas meter.

Unable to use this integration.
Sensors: sensor.gas_consumption_per_weighted_degree_day and sensor.gas_prognose are not available due to errors.

Suggestion for product improvement:

Create an opportunity to deploy the integration more than once so that more than one device can be monitored. This can be several gas boilers, but also several heat pumps, each with different characteristics.

Since a day or two this integration stopped working for me. I can't relate it to an upgrade of the component or Home Assistant.

In the devices -> integrations screen, I'm faced with the message Retrying setup: No columns to parse from file. In the Home Assistant log files I've this message

**What I've tried already**
- Reloading the integration
- Setting a different weather station
- Deleting the integration and re-adding it
- Redownloading the integration through HACS and re-adding the integration in HA

**My assumption**
It looks like the integration fails to retrieve data from KNMI. Following the URL from the code to https://www.daggegevens.knmi.nl/klimatologie/daggegevens brings me to a `503 Service Temporarily Unavailable` page. The site seems to be down.

Can you confirm my assumption? And do you know if it's a temporary thing or that the KNMI has shut it down for good (in which case the code needs a refactoring to another KNMI API).

Hi Ernst, my HA gives me this wearning in the log. As a rabid user of the degree days integration, I would kindly ask you if you would be willing to look into this?
