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.


We have 1 HS100 plug and 3 HS105 mini plugs and 2 HS200 smart switches.  The HS100 has worked perfectly for over a year but since adding the mini plugs and switches we have connection issues.

They randonly lose connection and our Alexa app says they are unresponsive.  They are also unresponsive in the Kasa app.  Any suggestions on how to correct this problem/

I am having this issue as well.  I haven't added any smart plugs, mine just cuts in and out when I am not home, and it barely works with my Echo now.  I was told its a router issue and the DNS has to be reset or something.  I am not familiar with router stuff, so I am lost.

I have almost the same problem. Once that I set up the Plugs mini they start working good but after 2 or 3 days they stop working. Neither my smart assistant nor Kasa app can detect the devices. I need to set up again each device. If someone has the same problem I need your support.

I have the same problem - no addiotns - no changes - not sure when the firmware was updated but it only started happening in the last 1 or 2 months.

Will have to ask for refund on my 7 units if there is no solution as my units are not easy to get to  ie under my house (where I have excellent WiFi reception due to the various access points I have)

All my units have reserved DHCP addresses so that is no thte issue and it happens with two different routers ie I have exchanged my router with the one in my office so it is not my router - and all my other Wi-Fi devices do not drop off the network

I have the same problem. It started about 2 months ago. Before that I had several of the devices and they never had issues. 


Problem: set up device successfully. device becomes unresponsive in kasa app. there is no way to fix this. reset device by either saving settings or completely factory resetting. starts working again. a few days later the device is no longer working. process repeats.



I have the same problem. Really irritating. How do you save settings and will this avoid a complete re-install?

Exact same issue here. I have 5 HS 105 plugs and they will run for 2-3 days connected to wifi, then will loose wifi connectivity until I unplug and plug them back. Then they reconnect for another 2-3 days. Problem started around November/December 2018 (now end of January). I searched many forums, a lot of people reporting the issue. Tried all the tricks (FW upgrade, factory reset & reconfigure, move plugs in the same room as router : 10ft away. NOTHING WORKS.

I'm also experiencing the same issues as others in this thread. I have two HS100 smart plugs and both seem to disconnect from my WIFI on a daily basis. The problem started around December 2018 for me. I have tried to do a factory reset, move the plugs closer, verified my router is configured correctly and does not turn off, changed the channel frequency, but nothing seems to correct the issue. I have now temporarily replaced the plugs with another smart plug brand until the issue gets fixed. 


TP-Link, any chance we can get a new firmware to correct the issue?

Hey Everyone,  Thank you for your comments.  We will work with our Smart Home division to see if any performance enhancements are needed.  We will keep you all updated
