@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?
