did you find a solution to this?

I'd like to turn off the low battery notifications, i don't need to know every day that one of my sensors batteries is low

Did you figure this out in the end?

I'm getting the same issue, the gateway will randomly lose wifi connection, can be once a day or once a week. When it loses connection it says something in Chinese, I'll then go to the app and re-add it - wifi settings and all the devices are still set.

I have this issue, did you find a fix??
