Q: Can I plug in a power strip to the smart plug?

A: Yes, you can plug a power strip into a TP-Link Smart Plug and turn it on/off via the Kasa app or voice command with Amazon Echo/Google Assistant. The total draw and wattage of devices plugged into the power strip should be within the rated amperage and wattage of the Smart Plug.


Q:  Can the Smart Plug/Switch control multiple lights?

A:  Yes, they can as long as the total current draw and wattage does not exceed the rated amperage and wattage of the Smart Plug/Switch.


Q:  Does the Smart Plug block both plugs on the socket panel? 

A:  Yes it is possible, but it depends on the model of smart plug you are using.  If outlet access is a concern we recomend using the HS103, HS105 or HS107.


Q:  Can I use Smart Plug/Switch on my TV so that Alexa/Google Assistant/Home Kit can turn on/off the TV with voice?

A:  No, most TVs go into standby mode when you turn them off. Since the smart plug shuts off all power once the TV is turned off it would need to be manually turned on after power is restored.


Q:  Can TP-Link Smart Plug/Switch work with Apple Home Kit?

A:  No, our smart devices doesn’t support Apple Home Kit, however we are working on compatiblity and hope to have it finished soon.


Q:  Can multiple plugs/switches work with Amazon echo? If so, do I need to use separate names for each smart plug?

A:  Yes. While you’re setting them up in the KASA app, you will get the opportunity to set a custom name and icon for each smart device.  When you pair them to Alexa, you also can divide the smart plugs into group to control them. 

For example, you have two plugs, you could name one "Table lamp" and the other one "tree lamp”.  Then group them to be "living room lamps." Then you can ask Alexa to operate then separately or both. 


Q:  Can I ask Alexa "turn off power after 30 minutes" since KASA app has timer?

A:  No, Alexa doesn’t support KASA’s timer functions.


Q:  Do I need to buy Smart bulbs to be able to control lights with Alexa using your smart plug/switch? 

A:  No smart bulbs are not needed. The switch will control whatever is on the circuit that it's installed on, and Alexa will provide voice control for that device.


Q:  Is HS200/HS210KIT a dimmer?

A:  No, HS200/HS210KIT does not have dimmer feature. HS220 is a dimmer switch but it’s only two-way.


Q:  Can I manually turn on/off the lamp/other devices via the switch on the HS200?

A:  Yes, when the HS200 is connected to the electrical system properly, you will be able to control the lamp/other devices in the system manually.


Q:  Can HS200 work at two wires circuit?

A:  No, you will need at least three wires: Live, Load, and Neutral for the HS200 to work.


Q:  Can the HS200 work on two-pole switch as long as the other switch is always on?

A:  Possibly, but only after some circuit modification.  We don’t recommend you to do this, and can’t provide technical support for this kind of application.  Should you want to proceed, we strongly suggest you hire a professional electrician to install it.


Q:  Can the HS200 switch be used in a three-way switch light combination (two switches controlling one light)?

A:  It is possible, but only after some circuit modification.  We don’t recommend you to do this, and can’t provide technical support for this kind of application.  We offer the HS210 Kit for a 3-way circuit and recommend this be used instead.


Q:  Can I use HS210 KIT with ordinary three-way switch?

A:  Yes, but you have to connect only one HS210 to Line wire and the ordinary three-way switch to Load wire.

Same issues here, have many HS100 / HS105 / HS110 switches. Currently some of my HS100/HS110 switches fail to reconnect even after resetting them and trying to reconnect. Seems like a firmware issue as my DNS server does not even see the DHCP address request to obtain an IP address.


As a result these plugs have become useless. Seriously regret buying these (expensive) plugs who fail because of crappy firmware.

When can we expet these products to work as advertised?


It looks like the smart plug firmware has a bug/issue with obtaining/retaining an IP address. I see in my DNS server logs hundreds of requests from a HS100 plug that looks like this:

(MAC address anonimized to end with xx:xx:xx)


23:14:56 dnsmasq-dhcp[1690]: DHCPOFFER(enp0s31f6) 50:c7:bf:xx:xx:xx
23:14:58 dnsmasq-dhcp[1690]: DHCPDISCOVER(enp0s31f6) 50:c7:bf:xx:xx:xx
23:14:58 dnsmasq-dhcp[1690]: DHCPOFFER(enp0s31f6) 50:c7:bf:xx:xx:xx
23:15:02 dnsmasq-dhcp[1690]: DHCPDISCOVER(enp0s31f6) 50:c7:bf:xx:xx:xx


There is basically a request every 2 seconds to obtain an IP address.

Mid Feb my TP Link light bulbs and electric plugs quit working with Alexa.  Alexa says "There is a problem.  Reload the app."  I have reloaded the app and still nothing works.  I would like a fix please!

Programmer here.  Same issue, HS300.  Please include firmware for the hs300, can work with you.


Edit: also, the windows formate update link is dead..

I am having the same issue across 6 HS100 devices, as is my son in an entirely different house. We are both IT professionals and no idea what else to try. 


Devices are local only or the button totally disappears from the app. 


Everything reset, reconfigured, latest firmwares. 


Have brand new AP now as well. Can see devices stay connected on the AP log except the six HS100 devices which regularly (sometimes In a number of seconds, sometimes hours)


devices show name on AP as HS100, other times the MAC address. Changes randomly


No other devices fail and stay connected. 


Fix this now please. 



como hago p cambiar la clave wifi xq se m reinicio






is there anyone who has issue when using smart plug to power up??

My Hs100s often show as unavailable in the app. When this happens their leds are solid red. Power cycling them immediately fixes the problem, no reset is ever needed. (Wifi signal is strong.) This is an awful problem. Help!
