Hello, I have been using homekit with ecobee3, roughly 10 Hue lights, Schlage Sense for about a month and everything worked flawlessly. All the automation tasks were executed properly by the Apple TV 4th gen (hub). All the scenes like Arrive Home, Leave Home, Good morning, Good night were done by Apple TV automatically. However, for the past few days, all the automation tasks just stopped. I did some tests and all of them failed. For example, yesterday at 4:00PM, I set a task to turn on all the lights at 4:05PM. At 4:05PM, nothing was turned on . So, today, I just reset everything (Homekit, lights, locks, ecobee3), including resetting the Apple TV to factory default settings. I re-paired everything to HomeKit. I did the automation task like yesterday and it still didn't work . Has anyone got this problem before? How do you solve it? Thank you P/S: It works again. No idea why. Anyway, I guess the problem is solved.
