Hi there. Absolutely 100% positive that this is true. I have lamps and bulbs in Yeelight app which are not showing up in MiHome app but not the other way around. Fx. Crystal pendant lamp SKU: YLDL01DL not approved on the European server. Now this LED Smart Lamp D2 appears to be the same.
I also have 2 Yeelight LED strips who’s colour can’t be set to regular WHITE light in the app but you can set it via a voice command on Amazon Alexa?!? Apparently there is a firmware upgrade that they selectively enable on some customer ID’s but not all ?!? Super disappointed with it. I started building a smart home lightning system on Yeelight in my summerhouse have now 10+ lights and 4 of them have major issues as above.
Way too many for only a handful devices. I could just imagine the level of complications I would have if I had 50+ lights like I have in my main house where I have Hue for the past 7+ years and never had any of these problems and only 1 spot light failing after 5+ years in use.
