XMcosy+

Forget this app. Try something else. Lights will not connect to my wifi. I had another XMCosy light set for two years that worked fine. They must have messed with the app with the “+” because the new set won't connect. They even sent a new controler and it won't connect. Forget this light set and try something else.

Unskipable full page Black Friday ad in an app that barely works to start with is insane. So regret buying an XMcosy lamp

Customer service when I bought the lights was outstanding; mine didn’t work and they sent me a new one and let me keep the old one in case I figured it out.. the app however USED TO work great and let me fully customize settings and patterns but now it won’t let me program more than one color or edit an existing pattern anymore. I have several patterned lights throughout my house and just love watching the colors change, so it’s annoying that the app won’t let me do that anymore bc you cannot do it from the buttons on the lamp.

The lights are great…WHEN they work. Frequent disconnect issues make using the app frustrating. Then, it’s not very intuitive if you want to do anything remotely custom or advanced. We expected to be able to create different scenes with various color combinations to run with a single click. Turns out that’s just not possible. A huge design flaw!

App won’t let me sign in and if i try to create an account it says already established

I can’t connect the lights to the app. I’ve tried many times turning them on and off on and off. It’s really annoying when you paid someone to install 18 land Scaping lights and they don’t work.

So far they have been great, only reason for 3 star is the scenes absolutely suck…. They don’t have any fading effects and no customization. For example it’s Halloween month and I’d like them to switch colors fading from pink to purple to orange. You can’t do that. For Christmas, I’d like to turn on multiple colors at the same time, you cannot. You only can choose one color or these horrible scenes. Please update this app to provide better scenes with customization. For example, each post should be able to have two different colors at the same time. You should also adding fading effects to multiple colors so we can match colors on our Christmas decorations. These seem pretty modern and very capable to do this, it’s the app that’s not developed good to allow this to happen.

We have two sets of rgb lights and have to use this app to attempt to control them. It’s beyond frustrating — when I launch the app it says the strings are offline. Actually connecting to them so I can control them works maybe 1 try out of 10. One string won’t take custom static colors anymore, only the preprogrammed options. The off and in schedule works most of the time, but not always! I dearly wish there was another way to control these, because using the app is close to pointless.

Get it only if you have a lot of free time Works great- but when it works though

I mostly use my device through an Alexa skill, so I rarely use this app, but it does seem to lose cache every few months and requires me to login again. When I attempt that login again, it actually seems to just be CREATING a new account each time, rather than logging in my existing XMCosy account that I login with my Apple ID. The creation fails with a generic error (likely because I already have an account), so they’re basically forcing you to create an XMCosy account now. This needs to be fixed!
