People laugh at me for my $40 dollar smart lightbulbs, but I laugh at those with $20 smart lightbulbs that have all sorts of annoyances
I started home automation with a Philips Hue starter kit but built my own zigbee network with Home Assistant later on. I'd say IKEA light bulbs, being around half the price of Philips, are pretty much on par with them.
The worst lights I had were OSRAM, they kept losing the zigbee connection and were PITA all the time.
The IKEA bulbs aren’t as bright, get overwhelmed if you send a lot of commands quickly (so you can’t implement a dimmer for example, without the light jittering as it dims), and don’t have the “turn power on-and-off quickly to reset to full brightness” feature (though this is nice if that’s what you specifically want).
