Connect the bulbs to nanoleaf app, then want to connect with Alexa, error.
Reset
Wanted to pair these bulbs with Alexa directly, all of them (12) requires firmware update before pairing process could be completed, each take 2 minutes or more.
Alexa with mutiple thread boarder routers in network ( two Echo studios, one Echo 4th gen), creates unexpected heavy data traffic to the router at home, eventually the whole network is down and requires reboot.
Gave up connecting these to Amazon Echo,
Reset everything, connect to nanoleaf app first, then to Apple Home, HomePod mini as thread router, Nanoleaf app shows bulbs on Thread, observe the wireless traffics in home internet network, unexpected traffiic seen.
More reseach shows IPv6 is required for muti-admin, turned on this in home interent, loop all the above processes, NO LUCK
Current stable steup is AVIOD nanoleaf app, give up the features in app, use Apple Home adaptive lighning, add Alexa as muti-admin control.
