Sonoff ZBMINIR2 setup problem

Hi, I bought a Sonoff ZBMINIR2 to connect to my garage lights, but having installed it, not only can I not see that on my Philips Hue system (in pairing mode), it can’t be found by the Sonoff eWeLink app, or Alexa, or Google Home. Can anyone offer any help as to how I might be able to get this to work ?

Thanks
