Hello. I HAVE THE SAME ISSUE!! My Yeelight strips have 2.06._0073 firmware version. I have many apple devices with iOS 13/13.3.1/13.4. Some Yeelight strips work only 12 hours after they become unresponsive ( no response) in Homekit on any version of iOS. At the same time all strips work fine in native Yeelight App (German/Africa server). But it doesn’t make any sense for me using native App because I have many scenarios automations in HomeKit!! FIX THE ISSUE ERGENT!! Why you add support for Homekit and not making any bugfix updates?! You’ll lose lot of clients on this.
