Justcool 3 Way Smart Dimmer Switch Kit: Wifi Timer Light Switch works with Alexa Google Assistant And IFTTT, Master Switch And Add-on Switch Dual dimmable, SmartLife App, NEUTRAL Wire Required, 3-Way

I have been wanting to smart connect my house for a while now. I've looked into getting smart light bulbs, smart plugs, and pretty much smart everything. The only thing that felt weird was installing it in the entrance of my house. I wanted to still be able to hit the switch and control my lights but also be able to turn them off using my Echo (Amazon Alexa). This worked out perfectly, I installed these in the front of my house to control the chandeliers and it has worked out perfectly. Now I can turn on the lights from my phone, through voice commands or just the normal away of just hitting the switch.

I'm VERY pleased with nearly all of the 20+ sets I bought. For the most part they're easy to install if you have a basic understanding of circuits and home wiring. Only reason 4 stars and not 5 is due to a seller response I read in the customer Q&A (dated June 6, 2019) before buying these that indicated you can use a second add-on switch in a 4-way circuit.I purchased 15 sets of 2 single-pole switches and 6 of the 3-way switches (which come with 1 Master and 1 add-on), and 2 of those 3-way switches were bought strictly to get the second add-on to use in two 4-way circuits I have. For anyone who may not know, I'm referring to places where you may have 3 separate wall switches that operate the same set of lights (I have this configuration of 3 switches both in a long hallway, and also in my back patio).Despite being pretty capable with electrical tasks, I have tried countless wiring configurations and I cannot get both add-on switches to work like the seller said you should be able to. I've emailed them and may update this if they respond with a way to do it that I'm not seeing.Again, ALL of the single-pole and typical 3-way switches (where two switches are used to control the same lights) are working great! However, here's where I'm at with the 4-way circuits in case anyone has any tips or may point out something I'm doing wrong:I've been able to wire three switches (Master, add-on, and second add-on) to have the Master and original add-on work fine... those two control the lights on/off, dim, connect to wifi, everything works great. But the second add-on will not control the lights. It has power because the blue light is on, and obviously the circuit is complete since the other two switches work fine, but I cannot figure a way to have the second add-on work to turn lights on/off, dim, or do anything except provide a means of routing power from the source to the Master.My set up which is allowing the Master and 1 add-on to work is as follows:-- Switch 1 (Master) replaced a 4-way switch (originally installed when I built the house) and is in the middle of the circuit-- Switch 2 (add-on that came with Master) replaced a 3-way switch on the end of the circuit with the load wire (to light)-- Switch 3 (second add-on) replaced a 3-way switch on the other end of the circuit with the power source (live/hot wire where power comes in)Switches 1 & 2 are the ones that work fine, but Switch 3 does not. I've asked the seller if something needs to be linked via bluetooth or wifi to allow #3 to work with a Master switch it didn't come with, but that isn't likely the case... it doesn't seem possible to me but I'm just double checking to see if I'm missing something relatively simple.I've tried installing the Master on the end of the circuit with the load wire (where #2 is now) and using the add-on's in the middle and power-source end, but doing that wouldn't allow any of the switches to work (it did allow the lights to come on but would not turn them off or dim). I also reversed that and tried the Master on the power source end of the circuit and add-on's in the middle and load end, but same result (lights on, but won't turn off or dim).I've also asked if there is any way to wire this and have all 3 switches work correctly... even if it means having to run another wire or two through the house, but I want to be sure these devices will in fact work correctly before I do a job that labor intensive. At one point I thought the issue was I may need another load wire on the other end (the power source end) or perhaps tie that end into the neutral wire somehow, but again that's not something I can quickly do to troubleshoot at the moment. It does however appear to have something to do with switch 3 having no tie-in to the complete circuit... it's sending power along but ins't looped in to interrupt or complete the circuit (i.e. turn lights on/off) since there's no "return" path.While I await the seller's reply to my email (or perhaps this review) I'd certainly appreciate anyone else's feedback if you think you have a solution here. I know it's very difficult to say without seeing the wiring in person, but I'm primarily looking for an answer as to whether this "should" be doable with my current wiring and it is likely the switches that aren't 4-way compatible, or if someone see's some other issue that could likely be the cause. I won't go into in-depth detail here as to what wires I have in each gang box or how exactly I have everything wired currently but can go into that further if anyone thinks they can help... but I can tell you the add-on's are wired exactly how the instructions state (the Master is slightly different due to being in place of a 4-way switch).My email for stuff like this is [email protected] so if anyone has ideas please contact me there, or you can leave contact info in reply to this and I'll get in touch. Thanks!

The media could not be loaded.  Paid $160 for these. Ordered 3 pairs of 3-way dimmers for dimmable LED bulbs. Paid electrician $215 to install per advice from seller. I set works fine. The other two not so much. I set flickers if not on 100% brightness. Adjusted wheel for dimming range but didn't work. Light just won't dim. Bought different, top quality Philips dimmable bulbs. Same problem. See video. The 3rd pair just doesn't work at all. Shuts itself off.UPDATE: Upped rating from 1 star to 3. Seller contacted me with some tips. Switches work now, but not optimally. I wish they would just work, and not "mostly" work. I spent too much money for "mostly".

I like the look and the responsive buttons however the lowest setting brightness is still really bright. I adjusted the manual on the master switch to the lowest setting but it is still too bright with the 6 LED lighting. My previous non-wifi 3way dimmer was able to adjust the lowest settings just fine. Unfortunately, I'll have to return this model.

I've been looking for a 3-way Wi-Fi dimmer switch, there are not a lot of choices. I purchased few other smart switches before, and I decided to give this one a try. There's no surprise to the product quality, it fits my Smart Life app. Most non-major manufactures use Smart Life app nowadays, and I have no issue with it. The app is updated regularly, the UI has been revamped recently, so it's a good indication for the long lifespan.So far,all work great.I have very good experience with This products and its customer service, this one is no exception. Overall I think this is a very solid product with affordable price tag.

Nice quality switch, I have two sets of them. My only dig, and it’s a pretty decent sized one. Is that it interferes with one of my other switches. I originally thought that it was just going to be one switch, because they share a common “line” wire. But when I installed the other, in a separate room, I still get the same thing. On the third and fourth brightness setting, those two switches will turn on a completely different light. But just on those two brightness settings. It goes off when you go away from one of those two settings. Other than that... it’s a nice switch. I just don’t think that it’s worth 55 bucks if it has that problem.

It's a three way switch replacement. The thing about 3 way switches is that they only break the hot leg, and the neutral is usually never in either of the switch boxes. It's just the way they wired them over the years. This requires a nuetral wire to function. Open your switch boxes and check before ordering.

My dimmable LEDs lights won't come on at all. Incandescent lights don't work either. I verified the black live wire with a meter. I verified the traveler wires with an ohmmeter. The white neutral wire is connected properly. The switches light up, they connect to wifi, and they make internal clicking sounds when activated, but there is zero output to the lights. Adjusting the dimmer wheel at the base of the switch doesn't help. The product description says that wire nuts are included, however none were included with my switches. Did I receive someone else's returned defective switches? Also, the instructions say to "...contact our service team" but there is no contact info provided.
