Yeah, good point. The “app setup” is built into android and iOS as far as I can tell (generating matter credentials, etc.). Better than 3rd party IMHO but not ideal, and a nonstarter for a lot of folks. Hopefully HA will come out with their own onboarding process at some point.





High frequency is generally bad for transmission line losses, so getting power from A to B is better at lower frequency — DC is a great option here.
If we switched to DC, many things would still flicker though as they would presumably use switching power supplies, but those could be relatively high frequency like you said.
Interestingly, airplanes use 400Hz, as transmission over distance doesn’t matter, and transformers can be made much smaller/lighter.
