This review focuses on the Caseta Dimmer PD-6WCL-WH (no neutral wire). I won’t spent too much time going over the issues, just highlighting a couple and making a recommendation to another, improved, Caseta Dimmer.

- Works without white neutral wire. If your older Home has no neutral wire, this is the best LED smart dimmer available.
- Quality product, and in many rooms the cons aren’t an issue
- Controls up to 17 8.5 watt led bulbs
- Has unique ability to modify/set the high and/or low end of the dimming range (i.e. set the dim range so a bulb/fixture will dim lower)

- Lutron certifies bulbs for use in the dimmer and many bulbs, including the top rated BR30 GE Reveals, will not work in this dimmer. We like to use the new ‘vintage look’ LED bulbs, and none of mine work properly in this PD-6WCL-WH Caseta dimmer.
- The problem must people have with this product is it’s inability to set a default dimming level. When turned on at the switch it goes to max brightness.

Many people, like myself, like that when using LEDs with a dimmer, you can buy bulbs brighter than you could for an incandescent, and it only adds 2-5 watts and virtually no heat. This allows you to light a room super bright if needed, but use the dimmer so you can tone it down for everyday use. Here in lies the problem with this dimmer. It starts at max ever time you use the switch. This is terrible for a bathroom in the middle of the night.

The last thing is the layout is complicated. Guests won’t know how to use it, and you have to pause and think before you choose a button (especially in the dark). It not like a GE paddle where you can walk by and quickly tap it up or down.

If you like the layout, I strongly suggest you check out the Caseta PD-5NE-WH dimmer switch. It uses a neutral wire and functions with way more bulbs (I check compatibility myself - if there’s no flicker, hum, or on/off flash they work). It also has a button for a preset default, but it is a little pricey - no more pricy than spending $54 on a dimmer and switching it out!

See my product review on Caseta’s more advanced dimmer (PD-5NE-WH), it resolves almost all of this products issues.

Nice kit. Installation of switches requires basic electrical skills, but nothing too technical. I did run into an issue with Lutron's instructions to replace three-way switches with this setup (you need to identify the hot lead and install the switch there), but it wasn't too hard to figure out. The bridge installed without any issues and works flawlessly with its app and Alexa interface. Remotes are a little fiddly to program, but I've seen worse.

The big issue is compatibility with fixtures. If you install these switches with dimmable LEDs, the fixtures must be on the list of compatible equipment provided by Lutron. I tried to use fixtures that were not listed as compatible and ran into serious operational issues (flashing, flickering, unpredictable dimming). Suffice to say that anything not on the list is likely to give you headaches, and it is almost certain that the super-inexpensive fixture you found is not certified.

Part of my home is an old farmhouse build over 100 years ago. While the wiring was upgraded a couple decades ago, they still didn't add a neutral line to any of the switch gang boxes. Lutron makes one of the few available smart switches that will work without a neutral. This kit comes with a hub, 2 switches and 2 remotes.

Installing the switches was easy, though I prefer the GE design where the wires are inserted into the switch body, rather than using wire nuts as Lutron has done. The hub was also easy to install, though it looks like it needs to be on the same switch as your WiFi access point.

The remotes have a lot of possibilities. I can put switches in new locations, such as on both ends of a hallway, without having to run new wires. And with the wall mount adapter and a new cover plate, it'll look like it's built into the wall!

My only complaint is that the switches are rather particular about the bulbs if you're using LEDs. Not all dimmable LED and CFL bulbs are compatible, and non-dimmable bulbs just plain won't work.

Heres the deal... the installation was a breeze and they work with homekit perfectly. The bridge is nice and sleep looking as well. Now for the bad... I really don't understand why Lutron decided not to have a favorite button in the middle of the main in wall dimmer like it does on the pico remote? After noticing this I actually had to buy some more picos just so I can have this function in some areas of my home where I don't want the lights to go to full brightness each time I turn them back on. This really upset me a bit and had I known this prior to installing them I might have thought twice and looked for another switch instead. The other thing I really don't like about these switches are the way they look. To me they look outdated and need to look more modern and sleek. So many other switched out there now that look insanely good, but just don't offer the same features. If Lutron corrects these two issues its a 5 star product all day.

I've tried 2 other brands of home automation dimmers. Neither of them worked for my situation. One was the X10 switches. Those never worked at all. Then I tried Leviton's solution but that required a neutral wire and I don't have one everywhere. This is a very easy installation. We have multiple 3 and 4 way switches. Instead of having to worry about having a neutral wire, this solution simply ties off the other light switches and replaces it with a remote. It is so simple.

I was concerned about the distance limitation from the hub to the light switches. We have a 3,500 sqft . I have had no issues at all with the distance. I've called their technical support a couple of times to get help with the wiring and understand if the solution will work in my home because of the distance. The people on the phone were very patient and helpful.

I've integrated the switches with my Echo dot and Echo and it works! Be aware that if you want to group a bunch of lights to turn on and off with a name that is similar to the names pre-programmed, you will need to create a group on the Alexa website. For example, I have 4 switches in my kitchen. I created a group called Kitchen Lights. Then I can tell Alexa to turn on the Kitchen Lights. I also used it with Apple's Home. It also worked pretty well. I've also integrated it with the Logitech Harmony remote. That also works pretty well.

My wife is happy that the outside lights are on when we come home using the sunset feature. I like that I can have all of the lights that I want turned on automatically when I come home.

Also, you should be aware that if you plan to install remotes on the wall, you have to buy a separate wall adapter. These cost about $7. This seems pretty expensive for a cheap piece of plastic. I don't know why they don't include those in the product when you are already paying $60 for a dimmer.

Be aware that the RA product line does not work with the Caseta system. If you have a really large house, you may need the RA2 system to reach all of the locations. I suggest trying out the Caseta system in the furthest distance from the hub to make sure it will work in your situation.

I just wish that they had a solution for my ceiling fans and lights. I haven't found a good solution that integrated with the Lutron and Echo systems. For now, I just used the Caseta switches for the lights and a traditional 3 way fan switch for the fans.

I use a few of these around the house, and I plan to expand the use of them. These work great for a smart home setup, and I use the Amazon Echo to control the lights. However, these are not perfect....they are just closer to perfect than any other option I have seen. So I will make a Pro's and Con's list, and then explain a bit of why I prefer them over other brands.

Easy install
Replaces existing switches
Works with Amazon Echo
Clean flat appearance (adjustable)
Optional remote (I do not use)
Works with nearly all light fixture styles
You only need a single IP address

You need a dimmable light
Does not dim LED the same way it does other lights
Requires use of Lutron App

Now, lets start with the install. This is simple, just shut off the power, remove the old switch, and connect this one to the existing ground, positive, and negative (and the pos & neg are not in any specific order!). They even include the screws and plastic wire caps, so it is twist on and screw it in. No tape (although you SHOULD use it!). So since you are replacing the existing light switch you do not need to do anything else, no wire runs and no electrical box install.

So now we move to working with Alexa, or the Amazon Echo device. I don't call mine Alexa, because my daughters name is Alexis. So everytime we talk to her the other her responds....whichever her we were talking to. I use Amazon. But it is nice, just say "amazon turn off the bedroom light" and get a quick "ok" and boom, darkness. It makes us lazy. Or rather, it stops the "It's your turn to get the light" arguments with my wife, and makes it easier to take care of the baby at 2 am without getting out of bed. But here is the catch, Amazon can only pull the information from the Lutron App. You CANNOT use ONLY Amazon Echo to set it up! You cannot even rename the device. So you are forced to use the Lutron app to set up all the home devices, and name them properly so they are usable with Amazon Echo. Once your entire setup is done you are free to uninstall the app. Although to be fair the Lutron app is pretty good in itself. But this leads to another concern here, if you use the device as part of a smart home you absolutely MUST purchase the Lutron this case I used Casetta, but since I do not use the PICO remotes I am unlikely to cross the 50 device limit. This is another $150 ish, but it is worth it.

Why would a $150 hub for controlling light switches be worth it? Well, if you are like me and are setting up a real smart home, you probably have a lot of other tech stuff in the house. A smart thermostat for example, or maybe even a server or two, a cloud device, and a firewall. For those of us tech geeks who have all of this, but do not want to pay for t-he expensive licenses, we use a free version of whatever we are using. In some cases for the firewalls you are limited on your number of devices. So, if I was going to connect 50 light switches in my house I would use up all of my devices....just to create a smart home. This is not worth it. However, Lutron made it easier, that little hub takes an IP address and that is it. All other switches connect to the hub, not using an IP address that would be counted as a device on the firewall. You have no idea how hard I looked for this particular feature! With all my kids tablets, the computers, phones, servers and cloud....not to mention the other smart home devices....I am already near my limit. This keeps me under it.

That covers almost all of the real issues. But the not so real issue that people forget about is that not all lights are made equal, ESPECIALLY with the older filament style bulbs being illegal to produce now. A dimmer on these bulbs worked every time, without any changes needed. But this is not the case anymore, the new light bulbs are required to be dimmable. If they are not you get little flashes in your light bulb while it is off....all....night.....long.Get a dimmable one and this problem goes away, however the LED lights do not dim well. You get off, 75%, 100%. Nothing lower then dimming is not really possible here. However, I got the dimmer because it is cheaper than the regular switch, and who knows....I might find a good bulb that dims properly.

My husband installed these throughout our home and synced them with Alexa as a birthday gift to me. I’m the wife that comes home and turns on every light in the house and then walks out. Now, rather than having to run around hitting 17 light switches before leaving again (or uh, just being a terrible person who leaves them on), I just very smugly yell “Alexa turn off all lights!” and saunter on out. It’s been seven months and it still hasn’t gotten old. Alexa will also control the dimming settings and such. The future is now, folks. I feel like a Jetson.

According to the hubby you should get smart switches, not smart bulbs, because they’re more reliable and can’t burn out. I can’t promise you he’s right but we’ve had exactly zero problems with these switches so far.

Whole system installed quickly, integrates with Siri and works with voice commands as I had hoped. I also installed several additional Caseta Wireless switches for additional lights, pico remotes and Caseta Wireless on/off for fans and they also worked with zero issues. I picked up the system at a great price with a Black Friday "Alexa" deal. If ordering switches for fans, make sure you only get 2-pole if that's all you need as they make two models. During the install I had a few questions about wiring and called into Lutron tech support and they answered the calls quickly, had US based support staff and told me exactly what to do. A+ across the board.

Pricey, but work as intended. I like connecting multiple switches to a single remote, creating a "master remote" which I leave by the door. Some LED bulbs do not dim well, but changing the bulbs fixed the issue. There has been no dropped connections and works flawlessly with Alexa. If you search for "Caseta advanced wiring", the manufacturer has some easy-to-follow tips on wiring anything more complicated than a single pole switch (one switch that controls one plug/light)

Though there are lots of options for smart lights, this is the most elegant because 1) the ability to tie everything to one remote and 2) smart bulbs or the much cheaper sonoffs require power at all times. This means manually turning the switch off disables the "smart" function. Disabling the switch and have it always-on requires operating the lights only via Alexa/google which sometimes can be finicky (if you're sick!) and will be useless if your network goes down. 3) finally, my new apt has many 3-way switches all next to each other and I dislike figuring out which switch is on but in the off position, etc.. and for this switch, on is always on, off is always off.

Minor complaint - Turning the lights off makes them dim quickly and then off. I don't know why that bothers me, but I think there's a way to fix it and I'll probably change it.

In the future, I'd like to see lutron make
1) a wall plug that wires into the wall
2) a 3 switch 1 gang version with enough amps to toggle bathroom light/fan/heater.
3) a motion sensor tied to the hub (like phillips hue)
4) a single button switch (if it's on, turns off. If it's off, turns on)
5) GPS tie-in to turn on lights when you get home.

I am loving this system and it's integration with Alexa. I'm slowly upgrading my house with this system and I've noticed that I get greater than a 30' range on some of my dimmers. I actually just bought a second Dimmer kit since the price dropped to the cost of two in-wall dimmers, so I now have a spare bridge or can use it at another property. At this point, it's worth it. I have some exterior lights programmed to turn on in the early morning and again late at night as a security measure.

Others have noted that the in-wall dimmer don't have a favorite setting, but I won't ding the item for this. With Alexa, I can turn on the lights to the percentage of light output I require. Also, I ran cat5e and cat6 to every room in my house (best decision ever) so I have placed the bridge in a central location to maximize connections.

Therefore, this device for my usage and at the moment, I should not have issue with the 50 device limit.
