Welcome! If you have any questions, feel free to ask anytime.

@ap2017 Got it. English site is just outdated. German site has latest images with Node 8 http://www.iobroker.net/docu/?page_id=2563&lang=de

Thank you for your efforts, please update the official Windows Installation page http://www.iobroker.net/docu/?page_id=8390&lang=de

@klassisch Thanks, multihosting could be a good idea. I have currently Raspberry with Z-Wave and mySensors, all work fine, but when I added Flot and History for charting, system became barely responsive. This is what triggered moving the whole thing to a more powerful platform. I have small cube 4GB i5 PC handy, have Linux Mint installed and ioBroker. May be I will use it for Flot and History only. How difficult is to setup multihosting?

@Qlink Thank you for your help~ It will be perfect if this exe tools can work as an adapter.
