Installatie probleem; 'type' object is not subscriptable

[ibl129]

In Home Assistant komen na de instalaltie van 0.8.2 de sensor niet meer 'up'. Als foutmelding krijg ik:

This is a bit weird. I think/hope is it has something to do with a wrong python version. Can you go to your Home Assistant Frontend -> Configuration -> Info (use the copy button in the System Health block), and paste the information here?

It looks like that https://github.com/cyberjunky/home-assistant-toon_smartmeter/issues/23 has the same issue as well, and it seems that is in the same context.

Issue should be solved with 0.9.0-beta-5 (or later). Can you please validate that for me?
