Zigbee Bridge Pro Compatibility

I bought the device Zigbee Bridge Pro (Model: ZB Bridge-P ) for control my 4 devices Sonoff and 3 non sonoff devices but I can’t add this devices connected with Zigbee Bridge.
First I add the Main Zibee Bridge in ewLink app.

Second I put de devices in paring mode after that I search with ewLink app inside “Virtual Zigbee device” I search new devices but never found any.

The two devices is in same local 10 cm only

What wrong in this method?

only works with sonoff zigbee devices

Some standard ZB3.0 devices like IKEA light bulbs should work, but other modified ones won’t; And it is the same thing for other brands like Aqara
