In my earlier openHAB blog posts I automated the installation of extensions and linking of Channels to Items. Another problem I’m facing is the configuration of items. Again, that’s very easy in the UI - if you are willing to click through the list of Items, and manually do all the steps.
Among other things I’m using the binding-yahooweather and the binding-ipp bindings, and the first one needs configuration before it can work properly. For the second one, it righly discovered a laser printer in our network, but occasionally when openHAB requests the status information, this spins up an internal disk in the printer. Therefore it is feasible to increase the time between checks - it’s just the number of outstanding print jobs anyway. Doesn’t matter if someone reacts 5 or 15 minutes later, if the problem was not discovered instantly.
