Ring has solar path and fence lights but they no longer integrate with Google Home. Are there any brands whose software support for the next couple of decades? By my own research, there doesn’t seem to be a better option than Hue + a solar battery bank. I’d really prefer an all in one unit without wires though.
Are you specifically looking for battery operated? Because you could just get a smart outlet and attach them to it if they were wired.
I’ve yet to see any battery operated yard lights that are worth buying - heck, I’ve yet to see one that lasts more than a year.
