Yeah I had those wemo switches in my old house and their servers were unreliable as fuck all the time (app was straight garbage). I'm not even surprised they finally pulled the plug. They're on my shit list forever now.
It costs more but I went hue and couldn't be happier. Spent too many years complaining about how it was expensive but God damn if they don't just work and Phillips I trust far more to not just shut shit down (and even if they did, I can still make them work since it's not proprietary).
