Doesn't work very well as a Z-Wave controller
358548
I decided to go the RaZberry route to build a custom Z-Wave controller instead of one built by a company so I could program it myself even though they have software out of the box to do most all functions you need with this card.  Going with a Raspberry Pi and this card is cheaper and I believe more flexible, robust, and faster.  I highly recommend it. I was up and running controlling my first switch in under an hour, including me playing with the Raspberry Pi.  Never connected a keyboard or mouse to setup either.  SSH followed by tightvncserver for a graphical interface to access the system via my laptop worked great.  Now I use a web browser to control all my Z-Wave devices.  Huge community support.

Well bought two more devices, one the same as I had, and a new GE Switch/Dimmer.  The daughter board doesn't handle the devices properly showing them as dead as you try to control them based on distance.  I know Z-Wave devices chain so as I add more devices hopefully this issue will go away.  Currently I just had to move the Raspberry PI closer to the switch.  I took a star off because my home isn't that big and the entire house should be covered.

The system works well when used in conventional mode. I tried using it in YardMax mode but my dog got zapped once when she strayed over the wire and she continued to get zapped even after running back to the correct side of the boundary. We had to scramble to get the collar of off her so that she would stop yelping.

I have purchased two of these for integrating into my Samsung SmartThings system.  The integration went smoothly but the actual operation gives me some headaches.  I have Cree 40w LED bulbs (x3) in my ceiling fans and with this switch anything under 20% causes them to go to full brightness, 20 - 30% causes them to be properly dim but randomly flicker, then 30% - 100% works fine.  Also about 1 out of every 10 times I turn them on they don't do anything.  The blue indicator light on the switch turns off indicating that the light is on but no light output.  I turn the switch back to off, the indicator comes back on telling me its off, then back on and they work fine.

There is no adjustment for minimum on the switch like I've seen on many non z-wave devices.  In face this one replaced a non z-wave dimmer that worked perfectly but that was adjustable.  It would be nice if these were adjustable also.  Really can't recommend them because of this.  It's probably fine with regular incandescent bulbs but the reason I bought these is they are supposed to work with CFL and LED.

EDIT: I have switched my bulbs to Phillips warm glow and most of the problems went away.  There still is no minimum adjustment, which is unfortunate, but the Phillips bulbs operate much lower so its not a big deal.

It works well but the signal drops about once every couple of months which requires turning either the camera or receiver off and on to regain connection.  I'm not sure if this is because of electrical fluctuations or just interference.  I have made this occasional hassle easier to correct by connecting z-wave controlled switches on the power plugs so that these can be switched anytime there's a video problem even when not at home.

Does not seem to work very well.  Could be my application

I can use this strip, but it really does not do what I needed to be done. I wanted a strip with a control outlet that would serve to trigger other outlets to turn on/off with the unit plugged into the control. This strip doesn't do that. I will keep the strip however as its intended purpose - keeping control of phantom power losses from things like cell phone chargers - is useful.

I bought three. The button has to be pushed correctly to set up and override Z-Wave.  Works great with my Z-Wave controller.

This controller is for the Wii (plugs into the Wiimote where the Nunchuk normally goes) and gives you a GameCube controller look and feel. It's a real licensed Nintendo product but not actually designed by them, and that's the problem.

The ZL/ZR buttons are too recessed so your finger will hit the gamepad shell before the button is fully depressed. There's too much vertical travel compared to the GameCube pad.

Likewise the left analog stick is raised significantly higher than any of the other controls on the face of the pad. To move from the D-pad to the left analog stick you have to lift your thumb up a much higher distance than you did on the GameCube pad, where switching between the two was easy. Sounds minor but in practice it's irritating.

Overall this pad isn't terrible, and it works, but it's not as comfortable and ergonomic as the GameCube controller. It's easy to recommend as a cheap spare if your Classic Controller breaks someday, but it wouldn't be my main go-to controller unless I had no other options. Unlike a lot of no-name third party controllers I'd say it's better than most of them, but still a long shot from the GameCube design it is trying to represent.

You need a z wave controller in order to make this remotely otherwise it is just a thermostat. I was not clear when I ordered it.

This seemed complicated to install with Vera Lite controller. After I did configure it works well and was easy.

The off buttons do not have  a function only the on buttons, but overall a great way to control a lot of zwave devices using Vera Lite.

This product sometimes seem to loose connectivity with my HS3 system. Could not figure out why yet. All of my other z-wave (not z-wave+) work consistently connected to the same system. Since it is z-wave+ I thought it would have at least the same range or better.

I'm using this to control a 500 watt in ground pool light that is located in a dry outdoors pool electrical enclosure located about 25 yards from the house and about 40 yards from the the smartthings hub.  While it is doing its job just fine, I had to add a zwave extender to the outside house receptacle to get the signal to it- so not necessarily the most sensitive zwave receiver around. With that said, it is a pretty long distance and once the extender was added, the switch works 100%.

So for some reason Amazon and google brought me to this device when I searched for Z Wave sensors. This product is NOT Z Wave. I'm sure it would work fine if you have the other systems its compatible with I was unsuccessful when trying to pair it with MiCasaVerde.

Stereo plugs don't work in many controllers, had to buy adapters to make it work.

Easy to install and easy to program, but I can't get Alexa to recognize it and I can't get the app on my Android phone to connect.  I have it set to lock when a nearby motion sensor is tripped, but it only works about half the time. Not sure if it's my z wave or not; there are plenty of devices between it (closest is 3 feet away) and my hub for it to bounce through, but it always locks when I try via my smarthome app.

I wanted to use this to connect two different audio signals into the same connection, it didn't work like this. I figured as long as only one audio signal was active, one disk player turned off and the other on, that it would be ok. This was not the case as soon as the wire was plugged in from the second device, even though it was off, the sound went way down. Even with the second wire not connected to any signal the sound still went down. It still works to switch wires so that I don't have to change them on the back of the devices themselves, just not two at once. I was hoping this would allow me to use two sources without having to change wires.

SmartThings does a great job at lowering the standard for devices and hubs. I don't have a problem with any zwave devices, seems like their poor zigbee is behind the curve. They die or lose connection and they don't notify you that anything is wrong till you notice that only one of your six door sensors still work... Don't use this for vibration either. Mine used to work great, but slowly experienced more and more false positives and there is no way to adjust sensitivity..
