Automation in MiHome App failed for YeeLight 2nd gen White Light after firmware update

I have both of my MiHome gateway and YeeLight 2nd gen White Light at China Server.
After the recent firmware update, the automation stop functioning even if I tried to delete it and re-create it.

I used to have a human sensor to turn on the light if it senses someone is around.
It is not working now.

可以麻烦你看看吗?

非常抱歉这么晚才回复您,您能提供一下设备的固件版本吗?在您升级之前,感应开灯的功能是可以正常使用的吗?

图中有我灯泡的固体版本和米家的软体版本。

升级前是没有问题的,人体感应器是可以打开灯泡的。
现在如果关了灯泡,每一次在米家里打开灯泡,都会显示下图。


好像灯泡断线了。可是当我用Google Home语音开灯时,又可以开。
我也不知道是为什么了。
我也试了重置灯泡,也是一样。
