Additional context

Sadly this is quite a complex issue... it seems HomeAssistant sets all attributes to null on switch off. I implemented that in iobroker, too. But that leads to the issue, that those attributes stay null until they are updated again in ioBroker... so I added code to read the attributes on switch on again. This currently borks up some tests, because the timing is quite difficult. Probably that won't lead to issues in real live, but it might... let's see.
