I was so excited to Yeeligh JIAOYUE 650Ceiling Light... before got it.
Pairing with application is terrible because if you paired remote control with before, application will not see a lamp. So you need to reset it (5 times turn on/off) to be able pair it with smartphone.
Official application for android seems to be good, but it can't remember ambient light state after lamp turned off. Saving it into presets doesn't keep it too; application isn't very responsive when working with lamp's settings frequent (sometimes lamp doesn't react to application actions). Also there are no scenarios to interact with other devices so we smoothly approach to --->
---> the other application to control the lamp is Xiaomi MiHome - I bought this lamp to work definitely with that application (because your lamp is positioned as a product of a well-known company Xiaomi (or may be it's partner)). But I was really disappointed about it. First of all, somehow my Xiaomi Redmi Note 4X isn't compatible with this app, so I forced to download it bypassing Google Market. Alright, not a problem! Finally I got latest build on my phone. Set Europe region and russian (tried english language too) but it can't see the lamp! Lamp resetting didn't helped. Ok, defined Mainland China/English language. Reset lamp again - finally app see the lamp! But it can't see a remote control! Goooooood! Nevermind! Nice application, sweet presets, comfortable customization. Let's see scenarios. Whoooaaa! Chinese characters!!! UNUSABLE. I don't know if it depends on you, or should I write to Xiaomi devs.
Guys you should do something with that fast. All of those issues are really annoying and it making impression that your product is VERY RAW. For now I can't enjoy this lamp, because spent whole day for those dances with a tambourine.
