I have had a yeelight 650 without a starry sky for 2 years. For some time now this lamp has been going offline a few times a day. the connection is very good because the router is practically next to it. this is not acceptable. it is the same with my yeelight 450 without a starry sky. my MI ID is 1848399647 (Mi account). the yeelight 650 has the firmware 2.0.2_0056 and the yeelight 450 has the firmware. 2.0.2_0048.
