I spend way too much time having to fight with this app. But the last week has been horrendous. The device is always unreachable. I unplug/replug, and it sees it. Works long enough to turn the bulb off at night but then unreachable again in the morning. I've had it. I love smart bulbs, but in the future, never getting any that use this app. UPDATE: The constant 'unreachable' status appears to be due to having a 5G or 6G network. Wonderful. 🙄
