So everything was comissioned and working ok. Although I couldn't see anything on the app - it said I couldn't connect for some reason on "home" network.
Anyway, new wifi router was installed after the last one died - and I've followed the guide here:

And all the settings seem ok. but the dongly keeps flashing (over an hour now - no change).
Also the wifi to the dongle only stays alive for about 10s at a time which makes it a pain to configure since it's not seen as a secure or internet connection.
Anyway, does anyone have any ideas? It's connected on channel 7 on 2.4GHz network.... I'm out of ideas!
