Edit: Well I proved its not a wifi issus. Completely turned off my wifi. I was still able to use Zwave network. So what in the heck is causing the devices kill the USB passthrough?
@Holdestmade have you had connection issues with yours?
So I got 3 of them, to put on each of my hubs. Started getting notifications my network, for example zigbee, was down. Then minute later, its back up. Check the history of the sinilinks and they are constantly becoming unavailable.
They are in easy wifi range but even if they werent and wifi was lost, that shouldent kill the USB pass through, right?
Heres my history from the 3 sinilinks I got. 5:54AM I did full reboot of HA device just to get a fresh start. It didnt help as you can see.
