So I woke up to a weird problem this morning - none of my zwave devices operate from hub. Turning a switch on the device page simply does not work. Zigbee devices work fine. I tried rebooting the router of course, Where do I dig? [image]

no that is a gigabit switch and by nature will try to process and fragment jumbo frames. You want 100mb

Great. So just to be sure I understand. Do you believe putting in this hub between the router and the Hubitat hub will solve the Z-Wave radio problem?

If jumbo frames are causing yes. You could explore turning off the cloud backup temporarily.

Indeed I do have a Zooz 4-in-1 sensor. I have this one. [image] Amazon.com: Zooz 700 Series Z-Wave Plus 4-in-1 Sensor ZSE40 (Motion / Light /... Shop Amazon for Zooz 700 Series Z-Wave Plus 4-in-1 Sensor ZSE40 (Motion / Light / Temperature / Humidity) and find millions of items, deliver…

Well now I found a place on the support page to enter a "Warranty" problem. That seems to be the closest to my problem of the other two choices to send in a request, "Shipping" and "Subscriptions."

Z-wave seems to be completely dead this morning

Get Started Using C-8
