Over the course of a year I changed all our lights to Philips Hue. It was relatively expensive but I bought most of the bulbs on offer (pre brexit on Amazon) so got most of them half price. We rarely use the app as we have motion sensors in all rooms bar the bedrooms and have automations set up too. If you avoid the colour bulbs and just stick to white ambiance the price isn’t bad. The system is rock solid and never misses a beat. I would never go back to non smart bulbs. I do not see much value in the colour bulbs though, which is good as they are significantly more expensive.
