I have a synology 1515+ NAS, does anybody have any experience with the following USB devices on it USB 3 ports.

1. Honeywell HGI80 interface
2. Aeon Labs USB Z-stick gen 5
3. Dutch Slimme meter cable (tested this works directly on the USB 3 port)
4. USB 2/3 hub to put all the devices on one USB port of the synology.

And does anybody knows why the Aeon Labs USB stick has a very long delivery status? From the 20 or so
domotica shops in the Netherlands and Belgium no one has one in stock.
