Fan Speed Control Wall Switch

[Metal] This unmanaged switch is easy to mount on a rack or on a wall. Easy to verify speed via lights that glow different color indicating 100 Megs, etc. Compact in size it worked right out of the box as expected. The AC power cord is one that is the standard for PC computers so longer cords are readily available, if you are not close to an AC outlet.

[Yes (WiFi Only)] This is a review of a free product received from TP-LINK for testing and feedback as part of their review program. I replaced a standard manual wall switch with the HS200 Smart Switch. So now my Living Room Chandelier is connected by Wi-Fi to the Internet and can be remotely controlled using my Smartphone or Tablet from anywhere in the world. I had a single switch wall box which turned a large decorative Living Room Chandelier On/Off. I replaced that manual switch with the HS200 Smart Switch. Since the Chandelier is visible to the street, through a window, I reasoned that having it controlled by a Smart Switch could help deter burglars. I had no problems installing the HS200. My existing single switch wall box had a Neutral Line and I used the plastic HS200 Switch Plate. As for manual operation, a gentle tap on the large rectangular button turns the HS200 On or Off. It's a momentary switch. Very little movement is needed to toggle between On and Off. An internal glowing circle of light makes it easy to locate the Smart Switch in a dark room. Below the main HS200 On/Off switch are two small rectangular buttons. RESET for an App or Factory Reset. RESTART to reboot. The HS200 works with Kasa, a free Android and iOS app. Kasa on your Smartphone or Tablet can turn the Smart Switch On/Off locally and remotely. Voice commands work on Amazon Alexa devices (Echo, Echo Dot, Tap). With Alexa, multiple TP-LINK Smart Switches and Plugs can be grouped under one name. HS200 Wi-Fi operates on the 2.4GHz band. That gives it a good Wi-Fi range and makes it compatible with all routers. If the 5GHz band had been used, the speed increase would have been inconsequential, but the range would have been less and older routers wouldn't have been accommodated. I've been using TP-LINK HS100 and HS110 Smart Plugs to automate my home for several months. They have worked great. My Smart Plugs control a fan, desk lamp, air conditioner, and TP-LINK NC250 Security Camera.

[25.00 W] this switch was a perfect upgrade for speed and poe ports

[1] Big fan of the two-way switch that allows you to either speak for a moment, or leave the feed on permanently.

[46.30 CFM] Great fan. So happy to have 4 pin so I can control with my bios fan pattern.

Great fan. So happy to have 4 pin so I can control with my bios fan pattern.

[30 x 24 x 8"] Very bright. Wish it had an in-line switch, rather than plugging and unplugging at the wall.

[Internal] .....The switch is great. No fan, well made, very low power, and it only gets mildly warm when fully loaded. unlike my Trendnet PoE Ethernet switch - which is also very good the GREENnet switch has a built in power supply.

[44.5 lb] I am a physicist. (energy physics not matter physics). I am also a sound engineer, coincidentally, the control of sound energy. This amp is VERY GOOD for bench testing audio control devices and speakers. The addition of an unbalanced input makes it very handy for typical bench tests. Because I am retired I also use commercial speakers for my home stereo system. Use of commercial speakers is much cheaper than consumer speaker products that, by and large, do Not provide full range audio despite deceitful specs claiming otherwise. The commercial speaker is also built to last and far more reliable than consumer designs. (will last decades under home stereo use... my last amp lasted 31 years... speakers are still going strong) I use this amp as my home stereo amp driving 1,200 watt rated commercial speakers that actually reproduce 20Hz. (actual amp power use rarely exceeds 75 watts peak and 25 watts average) In that unique use... the amp fan noise is detectable so I place it behind a glass paneled cabinet. Aside from fan noise, the amp performs very well and for the price is one of the best bargains there is. Keep in mind... the typical consumer stereo amp is Designed To Fail and the primary reason is.... no active fan cooling. (a flawed design that minimizes ambient noise) The amp provides plenty of dynamic headroom (nearly 6dB under typical home stereo use) and presents no excessive noise floor problems. I use a receiver with balanced XLR outputs, a balanced 31 band EQ to drive the amp and control volume. My speaker connections are Speakon. Bottom line... A very good simple amp for multiple purposes at a very good price. If you are an engineer who loves music and movies you will quickly recognize the wisdom of putting up with a bit of fan noise to achieve excellent performance and very long term reliability.

[White] I added a 6 port volume control switch to use the amp in multiple rooms and outside
