hardware: no issues with a dimmer, bulbs or bridge with a galaxy s8. the software: very unintuitive (will a routine fade in AND out? who knows because there's no instructions), update after 3 years: hardware still ok. software still sketchy with broken labs & ZERO SUPPORT. u.i overhaul takes 5 taps to change brightness of 1 bulb in a room instead of 2 from v4 to v4 10 0. home and away doesn't work on v480 to v4140. new candle effects only work on strip light and go v2, *NOT ANY bulbs*
