Enerwave Zigbee Switch not pairing

My 1st time on this forum so I hope I’m posting in the right area.
I purchased 2 Enerwave Zigbee ZB15S switches from Amazon. I have tried everything I know to pair them with no luck. I follow instructions and the blue light in front flashes like they should be pairing but can ST app will not find them. Both switches are doing the same thing. Any sugestions?

Maybe you would have to move the hub closer. Once you have them paired then go to the ST IDE and change their device type to Zigbee switch.

After installing the 1st one and not getting it working, I hardwired the 2cd in a box about a foot from the hub. Did not help. Still does not show up in the app.

press the program button 4 times and on the 5th hold it for 5 seconds. That will set the device in pairing mode

Did you ever get any answers to this or figure this out? I’m having the same issue.
