Hi Albert,
within the Fine offset Weather Station Binding it is unfortunately not possible for WH3000. I talked and analysed with Andy that the WH3000 has no possibility to readout the livedata. All the data is send to one website eg. wunderground, and from there you can read out the Data. Therefore you can use IpObserver Binding or a method described here Wetterstation ws980wifi in openhab einbinden - forwardme.de - SmartHome / Hausautomatisierung / Programmierung und mehr
