An error occured during getting state

The contact sensor is always closed and the switch is always off in the home app. They're both unresponsive.

Hi,
I had the same error with an Espon ET-2756, described in issue #15, where you can also find the solution to fix it (I had to allow the insecure communication for the IPP protocol.).
After a firmware update I had the error again, but it could be fixed with the same solution. Obviously some settings were reset.
Maybe this hint will also help to find a fix for an HP printer.
