But lately, say I want to turn the light green it’ll be red and won’t switch to green when on green color. ### 2/5 — Suddenly won’t work *2025-10-28, version 3.7.2* Suddenly my lightbulbs that I’ve been using for over a year won’t work with my Alexa. I can’t link them again. I can only control them using my phone. Pretty much makes them useless. ### 4/5 — Was working *2025-10-27, version 3.7.2* This was working well; the the wifi plugs connected to Alexa - but recently stopped working; the Skill can not connect anymore ### 2/5 — Not working *2025-10-25, version 3.7.2* No updates for over two years and I assume this is the reason it’s not working since I’ve got upgraded to iOS 26 ### 4/5 — Rreeeviieeeww *2025-10-14, version 3.7.2* Minus one star for ease of connection. Otherwise, great product for the dollar value and quantity. Suggest multiple purchases no doubt. ### 3/5 — When it works, it’s great *2025-09-25, version 3.7.2* When it works, it’s great. The problem is that multiple times a year, I lose the ability to use any of my pre-sets and color options and then after weeks, the options will randomly appear again. Nothing I can do fixes it. No app updates, no delete and reinstall, nothing! ### 3/5 — Used to be reliable *2025-08-26, version 3.7.2* This app used to be reliable. Twice now in the past year scene selection has been none functional tried emailing support but no response beginning to wonder if ther is any support at all !! ### 2/5 — Unable to customize colors on LED Light Bars *2025-08-04, version 3.7.2* It seems that whenever I try to open the customization menu to change the color of the present light, the app entirely closes. I’ve tried restarting my phone, and uninstalling and reinstalling the app but the same issue occurs. I don’t know what may be causing this, but I’m bummed that I’m stuck with the off white color that the LED’s default to because I can’t get into the customization menu without the app crashing ### 1/5 — Light Presets Reset Constantly *2025-07-23, version 3.7.2* The presets for the colors go back to the default every time the lights are turned off. It started with one bulb and then slowly it has gone to all eight bulbs that we have ### 4/5 — Scenes not working anymore *2025-07-11, version 3.7.2* It’s great and all, but the scenes not working anymore like I can’t access anything, all I can do is make my light one color. Please for the love of god fix it the best you can 🫩🙏🏽 other than that, changing the colors of the light is cool ### 1/5 — Stopped working *2025-06-03, version 3.7.2* At first this was easy to use, but if you have to make any changes the app stops working. When you try to delete it, clear anything it freezes and there is no help as that is frozen as well. Try going online instead of through the app and it was absolutely no help at all. Would not recommend this at all. ### 2/5 — Connection issues *2025-05-11, version 3.7.2* Initially was working fine, but a year or two later the bulb has started to randomly disconnect or randomly do automations. I had a disco pattern that turned on in the middle of the night waking me up multiple times. The light has disconnected multiple times today and I had to physically turn off and on to fix the issue or re-pair. Will switch to a different brand if issues persist. The app also needs work as it has a lot of bugs. Can’t click on menu items like the help tab. The app just crashes. It’s pretty clear this app was feature driven and not stable. ### 1/5 — Stopped working *2025-05-03, version 3.7.2* Now I have lights that can’t be connected anymore through the app. This is why the hue brand stuff is so much more money. It’s supported. This is cheap knock off garbage. ### 1/5 — Do not buy *2025-03-30, version 3.7.2* This app works decently when you first get it. It then starts regressing into something almost entirely broken. You have only 4 different colors you can “save”. Without fail, this app will completely wipe all your settings and saved colors. I’m at the point now where it resets all my settings anytime I close the app. I have 4 of their bulbs in use right now, and very frequently there is at least one that “doesn’t have connection”. All the others seem to work fine, yet there is one that just won’t connect, and usually the only way to “fix” it is to completely ignore it until it starts working again, or do a full unpair and repair, just for it to break again in the next few days. Please invest in any other product, these are not worth your time and money. ### 1/5 — App Feature No Longer Work *2025-03-29, version 3.7.2* The “scenes” feature in the app, that lets you choose from preset lighting settings, no longer works. If I select that option, the page doesn’t load anything and is completely blank, even though it worked as recently as a week ago. ### 1/5 — App doesn’t respond *2025-03-29, version 3.7.2* Since few day the app behaves odd. While trying to change the scenes nothing appears. I tried to reset and reconnect but didn’t work When click on help icon the whole app stuck can’t perform any action. Please help ### 1/5 — not working *2025-03-28, version 3.7.2* won’t let me hit any of the tabs, including the help tab, one of the bulbs can only display blue, and resetting it does nothing ## Most critical reviews (10 lowest-rated) ### 1/5 — Support Discontinued *2026-04-22, version 3.7.2* This app hasn’t been updated 3 years, and most of the help articles you’ll find online about with smart home integrations like Alexa and Apple are from 2022. As users are seeing increasing issues with the app features (failed connections, freezing, unable to access support), it’s clear the company has no plans to make further improvements to this product line or interface. The company (Lumiman) no longer seems to sell their smart bulbs in the States, even on Amazon. Essentially, any Americans like myself who purchased these smart bulbs years ago are SOL. My Lumiman bulbs are basically just regular lightbulbs now and this app has been consistently unreliable. Looking forward to switching these final few devices over to Phillips Hue to have a cohesive system in my home soon and be done with the PlusMinus app once and for all. ### 1/5 — Trash *2026-03-10, version 3.7.2* Freezes, can’t click around, uninstalled 10x still doesn’t work, can’t contact support, can’t use my lightbulbs… trash app, trash devs, trash products. ### 1/5 — Get a refund asap *2025-11-22, version 3.7.2* Not worth the hassle, sometimes it will work perfectly fine and the next day everything will just break on its own. ### 1/5 — Does not work with Alexa *2025-11-09, version 3.7.2* The Alexa Skill can not connect anymore; can operate the plug with their app, not Alexa. ### 1/5 — Won’t sync with Alexa *2025-11-01, version 3.7.2* All my Alexa automation routines are useless now. I used to have all my exterior lights turn on and off with the sunset/sunrise. Now I get home at night and it’s completely dark. Not cool guys. Please fix this issue. ### 1/5 — Stopped working *2025-10-30, version 3.7.2* Life had this app Since 2020. It stopped working with Alexa. ### 1/5 — FIX YOUR APP *2025-10-28, version 3.7.2* Worked well with Alexa integration for YEARS until it stop working. Tried disabling the app and reconfiguring the lights, only to be met with “we are unable to enable the skill at this time.” Waste of money and time. SMH. ### 1/5 — Was great till last week *2025-10-28, version 3.7.2* Hurt up and fix it can’t redone t to Amazon keeps failing can’t get it to work and it’s not just me there’s loads of people saying the same thing please sort it out ### 1/5 — Horrible *2025-10-27, version 3.7.2* This app has gotten worse over time. Now linking to Alexa is completely broken. Light bulbs constantly need to be paired. Pairing takes 15-30 minutes depending on how lucky you are. Don’t waste your time and money. ### 1/5 — Alexa Support Stopped *2025-10-25, version 3.7.2* In the past few days, all my LUMIMAN Bulbs stopped working with Alexa. I have about 30 of the A19 bulbs. Color change stopped, on and off stopped. These Bulbs have performed well for about 4 years plus. I have yet to have one burn out. ## Most praised reviews (10 highest-rated) ### 5/5 — Mrs. Molly *2026-04-15, version 3.7.2* Awesome ### 5/5 — Great product! *2025-10-15, version 3.7.2* Easy to use! So fun! Easy to install! Makes lighting fun & relaxing or whatever scene you’re going for! Love it! Will be buying more to replace a different brand that isn’t even half as good! Excellent! *cozy* ### 5/5 — Great product *2025-10-02, version 3.7.2* Still holding strong after 3 years ### 5/5 — I loveeee *2025-02-01, version 3.7.2* Such a fun light to have ### 5/5 — Cool *2025-01-31, version 3.7.2* Works and I like the multi colors available ### 5/5 — Just Do It ! *2024-09-26, version 3.7.2* The BEST, Eva !!!!! ### 5/5 — Smart Light bulb *2024-05-11, version 3.7.2* This is easy to connect last long and amazing features and price love it ### 5/5 — Great bulb love the versatility *2024-05-11, version 3.7.2* I put this plus minus smart bulb in a lamp in my bedroom and it is so nice to be able to change and control the temperature and brightness and color. I can make it dumb enough for my early-bird husband to sleep but bright enough me the night-owl to get dressed in my pajamas. Want to add to the romantic atmosphere? Easy! Want to occupy your toddler for 5 minutes and teach colors at the same time? Let him change it. Want to see your late night sewing project easier, turn it up! Want to relax? Make it dim warm light! This light is awesome I love it! ### 5/5 — Great app *2024-03-11, version 3.7.2* It’s got lots of great features and colours although it could have better sound content but it’s overall a great app. ### 5/5 — Love this bulb *2024-01-09, version 3.7.2* Easy to use and set on any option/color combo you can think of.
