Yeelight Smart LED Filament Bulb

Hello,

A couple of years I am using Yeelight Smart LED Filament Bulbs. One lasted about a year and it was replaced with a new one.

Recently I replaced 3 other Xiaomi philps bulbs failed (couldn’t connect to the app any more so I replaced them with 3 new Yeelight Filament Bulbs.

Unfortunately all of them randomly are blinking. Turning off and instantly back on. But this can happen for example after 10 minutes or after 2 minutes or 30 minutes… Randomly… Some times more often some other not…

It is really annoying…

Do you have any idea why this is happening?
