I'm currently using Apple Watch Series 2 with watchOS 3.2.3, iPhone 7 Plus with iOS 10.3.3, and Apple TV 4th Gen with tvOS 10.2.2. The OS are on the latest non-beta versions as of this writing. So far, device status update on the iPhone's Home app is manageable - a couple of seconds for Philips Hue (ZigBee-then-Bridge) and Koogeek (Wi-Fi), and about 5 seconds for Elgato Eve (Bluetooth LE) when accessed outside home from a cold launch. But in the case of the Apple Watch's counterpart, all the updates are painfully slow. They generally take more than ten seconds to complete after a cold launch, and sometimes it just outright fails (no response). This is while being at home. I have to wonder if this is simply expected, e.g. a limitation of the AW's platform, or something not being right. I also read somewhere that having too many Bluetooth LE devices may cause interference, so maybe having 13 Elgato Eve devices might be playing a role?
