Edited:I originally made a review stating how this product basically burnt out and caused a short circuit due to using it with an air conditioner in a short time span, but I now want to revoke that review.It turns out my air conditioner itself was to blame causing the breaker to trip, the compressor was failing inside if it.With that said, I have used this product on an air conditioner for about 5-6 months now. The air conditioner was a small 5000 btu, running at 400 watts. Granted there are surges at startup, and this plug is rated for resistive (heat loads) NOT inductive (motor loads) it handled it like a champ.Sadly I took apart my old one to see if I can see burnt circuitry and then threw my old one away. I will say the amazon seller/company contacted me about my last review to try to make it right. At that time I figured out what was wrong, and explained the whole thing like I have in this review, and they offered to send me a new plug for free considering I had bad judgement and threw my old one away.To me that is customer satisfaction, going beyond what they should have to do.I bought four of these and they work very well. However, as soon as I added one to my Z-wave network, it flooded the system with constant usage reports. It felt like a DDOS attack to be honest. Anyways, no big deal at all! I checked the manual and looked up all the configuration settings and set them to values that didn't cause a flood of reports.I set mine as follows:-Report change in wattage for 50watts (parameter 5 - Default is 5watts)-Report usage once a minute (parameter 6 - Default is 5 / 5minutes)-Report change in amperage for 0.5amps (parameter 7 - Default is 0.1amps)Once they were set that way, I had no issues at all and I enjoy using/having them.I like it. Totally surprised my wife. She didn’t know what to think when light came on. So small and easy to figure out. App is simple. Worth the money for safety and security.I love that I can plug my lights into these and control them remotely. These are so convenient to have and easy to set up with my phone.This works with the Alexa app and I've had no problems creating a routine that it follow and the dimming works perfectly with the app needed to first set it up. However, there is a more limited distance on this model versus their newer model. This requires 2.4 and doesn't support 5.0.It's a very inexpensive way to add alexa control with dimming. I would add that I have set the brightness and have rarely changed it. If you want to change the brightness via voice Alexa I would recommend one of the newer models.I am using this to turn aquarium lights on and off with Home Assistant. It is working great!I was aware this was a 500 series device when I purchased it. I have also read about many problems with the 700 series buggy chip sets when used in a large z-wave network so I specifically avoided them. I will skip 700 series devices and try the 800 series devices when they start shipping.It may have been the placement, some interference at my place, or user error; but I found the reliability of this smart outlet to be flaky compared to other Z-wave and Zigbee outlets in my home. It does seem like Samsung is regularly updating support of the SmartThings hub (and they've relatively recently sold the hubs to Aeotec) so maybe it'll be more reliable in the future. I've seen that happen with some of my devices. I'm not one inclined to use words like Z-wave, Zigbee, SmartThings, or Aeotec frequently; so perhaps their inclusion here indicates how much I've tried to make this work for me!Download the app; plug it into the wall and the rest is almost automated.Can control dimming; and time schedule. It has a surprisingly wide range of wifi.Very good overall
