Nest and Dyson Issues

I can not add Dyson at all.
I have added HCAS and both Dyson Local and Dyson Cloud. Cloud doesn’t find my email address. Local doesn’t work using SSID and Password. Only some of my Dyson fans have this label.
Nest doesn’t work at all. I use gsuite and will not change it to gmail. I use the old nest account too. I never migrated to google.

I use home bridge now with HomeKit. Nest and Dyson work great. The setup is so easy. Even with two step on Dyson. Why does Home Assistant not do this?
Home assistant also does not find one Wemo smart plug and has not support for another smart plug I use.
So what is wrong?

Why are you using third party integrations rather then the core integration?

The core app doesn’t work. Dyson uses Two step now. so adding this does nothing.
