IndexError: list index out of range

Hi there,

I've added your add-one via HACs and fired it up. Unfortunately it doesn't appear to start correctly but rather logs the following..

contact_energy: Error on device update!
Traceback (most recent call last):

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^^^
IndexError: list index out of range

Any idea what might be causing this? More than happy to assist troubleshooting.

Cheers, Tim

FYI: I'm not a coder but know enough to be dangerous.
I did some digging within api.py and added _LOGGER.debug(data) to find out what was being returned.

I found that my account returns 3 accounts; 2 of which are cancelled because we used to have gas with Contact but don't anymore.

'accounts': [
{'id': '501001420',
'nickname': '',
'status': 'CANCELLED',
'contracts': []},
{'id': '501001424',
'nickname': '',
'status': 'CANCELLED',
'contracts': []},
{'id': '501131230',
'nickname': '',
'status': 'ACTIVE',
'contracts': [{'contractId': '13xxxxx

So I changed line 74 and 75 (on my local instance) to the following...

        self._accountId = data['accounts'][2]['id']

        self._contractId = data['accounts'][2]['contracts'][0]['contractId']

So now it logs in but no data is returned...

At this point I'm well out of my depth!

Hmm, that's an interesting one. Could you please try turn on debug logging on the integration page? Example below is Meridian but it looks the same. Then hit the three-dots and reload? Wait maybe 10 seconds then turn off debug logs and upload them here.

Hi,

I am also not getting any data back. However I am not able to add the Integration to turn on debugging due to the message below:

I have added my details to the configuration.yaml file and I can see the sensors under the energy panel. Am I doing something wrong?

[codyc1515]

Ah sorry that’s right. This integration does not have a config flow. I will need to do a serious rewrite. Let me get back to you on this.

If it helps I've been playing around with the API today in PowerShell and stumbled upon this where he pulls the account information from a different endpoint.

If I access my account information at /accounts/v2 then none of the above "cancelled" accounts get pulled.

Did anything ever come of this? I have Electricity and Gas with Contact, and at todays prices it'd be great if I could have this information in HA :)
