I have 7 xiaomi / yeeligth lamps. 1 of them (this: https://www.banggood.com/Yeelight-Smart-Square-Remote-bluetooth-APP-Control-LED-Ceiling-Light-50x50CM-AC110-240V-Xiaomi-Ecosystem-Product-p-1376932.html?rmmds=cart_middle_products&cur_warehouse=UK) works as it should, when I adjust the colour and intensity of the light, switch it off (power off , electricity cut with a normal switch) and turn it back on, it turns back in the setting as it was turned off.
However all the others, 6, from which 1 is this (https://www.gearbest.com/pendant-light/pp_009792951215.html?wid=1640583) and 5 are this: (https://www.banggood.com/Yeelight-YLXD01YL-28W-Round-LED-Ceiling-Light-Smart-APP-bluetooth-WiFi-Control-Xiaomi-Ecosystem-Product-p-1130770.html?cur_warehouse=USA) never keep the setting after switch off and back on. They turn back on always the same, not remembering the setting that was actual when I turned them off. I did check the setting via the MI app, I have the setting for Default State and it’s on that it should remember, however it just does not. (actually tried both setting options, none helped).
Tried also setting up a custom default state and save it, did not work either.
I’m totally disappointed, the whole point me buying all these lights was that i can control the settings of each individually and have them as I like, however it just does not work as it should. My brother has the same lights (the round 32cm ones, which I have 5 of) and it works just fine for him.
PS: i did update the firmware of them too, not helped.
