I have a dozen different Yeelight devices. Following the firmware update to version 2 (was 1.something before) they are requesting DHCP renew every five minutes. While renewing, they do not respond for a few seconds to API calls, which results in frequent unresponsive behaviour. It might be related to a bug I have seen in ESP8266 (see here: https://github.com/esp8266/Arduino/issues/7020). It might be something else. While the devices are blocked from Internet access, they respond horribly and attempt IP renew (which results in lack of response for a few seconds) every five minutes. This is different from the previous firmware.
I have a few ‘yeelink.light.ceiling1’ with version 2.0.2_0192; A few ‘yeelight.light.ceiling3’ with version 2.0.2_0048 ; A few ‘yeelight.light.ceiling4’ with version 2.0.2_0056 - all of them misbehave when they cannot access the Internet (which is frequent here), even with local LAN enabled control (which works). It’s just that the 5 minutes interval kills me…
