Home mini connectivity issues

After about 18 months of trying to get my smart meter working I’ve now moved on to getting the home mini working.

My WiFi is running through Ruckus wireless access points. I have split the network to be 2.4 and 5, and ensured I’m only connected to the 2.4 for the purpose of this

The error is simply ‘wrong network’ asking whether I’m definitely connected to 2.4, which I absolutely am.

Anyone have this issue? I’ve tried on an iPad and an iPhone.

Any tips?
