My spouse was wary when I started making purchases to make our house more of a smart home. I’ve always had a thing for technology. I don’t just go out and purchase something. I look into things. I prefer a customized arrangement to one that is installed by an alarm provider, which necessitates looking out for incompatibility. Except for the fact that they functioned and weren’t a waste of money, he wasn’t very impressed with the few things I installed. He detested our timers and any Christmas lights, though, as he was about to install them. mostly because dad fretted about flames if we were gone for longer than a few hours. That’s what I noticed. It features a timer, an outside outlet, and remote access so he won’t have to rush outside in his pajamas in the bitter cold to disconnect it.

I kept quiet about having ordered it. But once I put it up for him and showed it to him, he was quite impressed with how simple it was to use. We haven’t encountered any connectivity issues. It connects to Alexa with ease and even the finicky SmartThings on my Samsung phone! I don’t really need that. I have total control thanks to Alexa and the Kasa app, just like my spouse. He employs me to perform any setting, though. I struggle to get him to put Alexa on his phone.

I’ve used WeMo for a long time and have a lot of indoor plugs. I purchased one of WeMo’s outdoor plugs, which are comparable to this Kasa plug when they first became available approximately two years ago. But I’ve always had a problem with sunset rules. When I first enable the rule, the plug turns on my landscape lights at sundown as I had specified. The landscape lighting is turned on well after sunset, varying from a few minutes to over an hour after sunset, although each day it gets later and later. The rule is supposedly active at sundown according to the WeMo iPhone app, but the bulb doesn’t switch on.

When I attempted to utilize many of my iHome devices, which I only use around the holidays since they are named, scheduled, and ready to “go,” they had stopped offering their app service, so I was forced to use the Apple Home Kit, which has never reliably functioned. To replace the ones I already have, I purchased a handful of them during a Black Friday sale. I already knew how to add it to my collection of Kasa devices because I have multiple Kasa switches and plugs that are in use. I set up and named two devices in only ten minutes.

It was only logical for me to visit Kasa for an outdoor plug as I had already purchased several of their smart plugs for inside use. The Kasa software has been improved from the initial plug. By far, adding this plug was the simplest part. Simply plug it in, launch the app, and press “+.” Then it appeared! It has been running smoothly for a few weeks at this point. As I anticipated, the plug turns on and off. It’s okay with Alexa. The Kasa app is constantly updated and is aware of every plug. I have absolutely no issues.


Does the Kasa Smart Plug function offline?
A: Yes, even if the Smart Home gadget loses its internet connection, such features will still operate.

Can Kasa smart plug be used without an app?
As was already said, the app is required for initial setup. Once the devices are connected to your network, you may stop using the app.

Why does my Kasa smart plug constantly lose connectivity?
Step 1: Verify the router is operating correctly. Check to check whether the smart device reconnects after rebooting the router and Kasa device. Verify that the Kasa smart device is receiving a strong Wi-Fi connection in step 2. To check the signal quality of the Kasa device, navigate to the “Device Settings” tab on the Kasa app.

Can several people use the Kasa smart plug?
If a second mobile device is required to administer your smart device, try joining into the admin account using the same email address and password on that second device using the Kasa APP.

When Wi-Fi is unavailable, what happens to smart plugs?
Many Wi-Fi-based plugs and switches will still function even without an internet connection, but some of the more sophisticated features, like voice control, won’t.

My Kasa plug is blinking blue; why?

What is the lifespan of a Kasa battery?
around 50 days
The only way to charge the device is to remove the camera and attach a USB-TypeC cable because there is no included dock. Amazing battery life. When they were installed five days earlier, they had batteries at 58% and 48%, respectively. A full battery should last around 50 days at this rate.

Is Kasa a WiFi user?
Using the Kasa Smart app on your smartphone, you can remotely turn on and off your smart plug as well as plan events or create scenarios. The Secure 2.4GHz Wireless Network used by the Smart Plug eliminates the need for a separate hub.

Is Kasa a reliable name?
The Kasa range of smart switches has my highest recommendation. Their software is simple to use and comprehend. Additionally, you may control all of your smart devices from their line using the Kasa Smart Switch app. The inclusion of a smart assistant makes the whole thing even better.

Are Kasa and TP-Link interchangeable terms?
Leading smart home system Kasa by TP-Link comes with Kasa Smart Plugs, Smart Bulbs, Smart Switches, and more. It is compatible with a number of other well-known smart home devices, including Google Home and Amazon Echo. You can now make customized Applets with IFTTT that cause automated actions on your Kasa devices.
