@coasterli I found other quirks in the English translation. Yeelight support might want to go over this thread, since some things have been updated in the recent version, but not everything. Here you go!:
"Firmware Update" I would just say "You're up to date!" (unless the "all" is referring to "all devices", for which "Firmware for all all devices are up to date." I would also suggest adding the firmware version installed on this screen.
"Share your device with family" > Not just family, but friends, guests, etc. Do I would reword it as "Share your device with someone you trust: Allow someone else to control your device." But honestly this is weird: it says "on/off, change the temperature, etc." - what is "etc"? What else could they do?! My suggestion is to use the above wording and then have a bullet point list of what exactly they are able to control.
Is "Message Center" supposed to be where users send messages to the customer support? It shows "No response" (as in "no response to your messages?"). If so, I don't see where to send a message to the helpdesk. Or is this a "Notification center", where you send messages to us?
I tried inputting another email address, but it didn't show up. I'm curious exactly how this works. My guess the email has to be attached to a Mi account: if so, this needs to be specified here.
Another comment: I just happened by chance to swipe left and found more options. You should make this clear somewhere that users have more options by swiping left on some elements.
