Error while setting up mindergas platform

[olafvs]

Hey,

Trying to set this up, bumping into this error:

2021-03-07 20:01:45 ERROR (MainThread) [homeassistant.components.sensor] Error while setting up mindergas platform for sensor
Traceback (most recent call last):
File "/usr/src/homeassistant/homeassistant/helpers/entity_platform.py", line 200, in async_setup_platform

self.update()
File "/config/custom_components/mindergas/sensor.py", line 109, in update
div = data.find_all("div", class="table_cell")[9]
IndexError: list index out of range

I only have two entries in mindergas. Maybe this has something to do with it? When I go into the site itself it also mensions this:

Prognose gasverbruik 2021
Er zijn te weinig verbruiksgegevens of het energieverbruik voor verwarming is te laag om een prognose te kunnen geven.

I guess the code needs an extra line or two.

One more thing. In the installation guide underneath Manual Installation you mention:

In the custom_components directory (folder) create a new folder called ziggonext.

I guess it shouldn't be ziggonext ;)

Thanks and keep up the good work.

Thanks you are right about the ziggonext 😄

Because there isn't a prognose available in your case the script cant scrape it and throws an error. If i have time I will add some error handling. So I think you have to keep upload your energy consumption to mindergas so it will calculate your prognose.

Thanks. I don't know how many entries it needs, can't find anything on the site about it. Anyway it's good for other people to know this in case they bump into the same problem.

Hi still no go. So I guess it needs maybe a year of data.

I felt lucky and commented out line 35 of sensor.py in the mindergas directory:

#add_entities([GasPrognose(username, password, name)], True)

Now I can use the component. This is not a perfect solution but I can use it. Just for reference of other people having the same issue.

[nelbs]

Thats strange, do you see the prognose in the dashboard on mindergas?

[olafvs]

No I don't, it's says not enough data.

[nelbs]

Okay, then you will have to upload more frequently I guess. I do this once a day (automatically of course :)) and I never had problems to calculate the prognose.

[olafvs]

Did you have a progonose the first year? I started 3 months ago.

[nelbs]

Yes as far i can remember i have

I still don't have a prognose.

However if you wrap the parsing in a try catch block it'll work just fine. See
