Your config looks openhab.cfg looks correct:
mios:house.host=192.168.0.2
mios:house.port=3480
mios:house.timeout=30000
The last two settings are default, so they're not strictly required (although they won't hurt either).
Your items declarations look correct, but potentially using an older version of the Item Generator. That should be fine.
For reference, here are my old definitions, just before I stopped using MiOS Weather plugin:
Number WeatherHumidityId "ID [%d]" {mios="unit:house,device:321/id"}
String WeatherHumidityDeviceStatus "Device Status [MAP(miosDeviceStatusUI.map):%s]" {mios="unit:house,device:321/status"}
Number WeatherHumidityCurrentLevel "Outside Humidity [%d] %" (GWeather,GMonitorHumidity) {mios="unit:house,device:321/service/HumiditySensor1/CurrentLevel"}
So, based upon the instructions here:
https://github.com/openhab/openhab/wiki/MiOS-BindingThere are a few items that could be missing:
a) Installation of the MiOS Binding itselfIf the binding is missing completely, then there will be radio silence in the openHAB log files, otherwise you'll see evidence of it starting.
If you're using Linux, and the
apt-get install type, then that's:
sudo apt-get update
sudo apt-get install openhab-addon-binding-mios
b) Installation of the MiOS Binding transformations:https://github.com/openhab/openhab/wiki/MiOS-Binding#mios-transformationsc) What's in the logs:https://github.com/openhab/openhab/wiki/MiOS-Binding#loggerThe binding will emit diagnostic information if components are missing, and/or having issues with connectivity.
