ZBBridge Pro as router

[ThorPrez]

I´ve flashed a Sonoff ZBBridge Pro as a router.
It´s running with 15.0.1.5 and Z2M can find it, so it´s paired and working.
Now I´m having a second device with 15.0.1 and Z2M cannot find it.

Configuration is the same, compared both as JSON.
I want to install the same version 15.0.1.5, but cannot find it.
Can maybe this be my solution ?

Kind regards,
Thorsten
