Not my experience. Hue is a hugely successful system and ours has been running quite reliably for many years.
My Nanoleaf installations as an opposite example are way more prone to unresponsiveness and lag.
Dismissing the opinion of others as either having bought junk or being unable to configure something is a bit on the harsh side.
I've probably lost more Smart Home products than you can count. And I have no idea what a Nano leaf is. But it's not one of the many extremely popular and reliable products being used by builders or enthusiasts.
These days I have about 50 HomeKit compatible devices (more if you include Ring products that are connected via Homebridge). I still maintain 1 Philips Hue lighstrip and 1 bulb, and the bulb is the only light out of 50+ products that routinely is non-responsive. The reason is because it has to connect to the Hue hub, and does not connect to Wi-Fi.
The over 40 Leviton Decora Smart wallswitches that I have, that are direct swap in for standard decora switches and look and function like any switch, never have any such issues. They connect directly via Wi-Fi, and take advantage of the well-designed series of Wi-Fi access points around the home.
Hue was good in the early days when it was the only such thing. It hasn't evolved one bit, and has been passed over by much smarter products.
