Smart home that's not so smart. Consistently need to restart app to control devices, it just on loading. Otherwise, it will take a long time to respond, that keeps you wondering if it's working. For example, turning off a lamp takes about 15s averagely, I have came upon 3 minutes delay which I actually forgot that I pressed the switch. Only smart part is to schedule automation. Wish there are usable widget as well to turn on and off devices instantly.
