I love these things! I bought a 4-pack last time and they just work. There was no hassle setting these up to work with Google Home.

Amazon title says you're wrong
You really shouldn't ever believe Amazon's listings. They are often wrong. Double check specs elsewhere.

Never used these before. Can I connect a power strip (which already has 6 plugs in use) to this and turn that power strip on and off with this plug ?
Depends on how much power you're drawing through these. If that is fine then, yes, you can do what you are describing.

You can also get power strips where each plug can be toggled on and off separately.

Our community has rated this post as helpful. If you agree, why not thank

I posted this on the Kasa smart switch 3 pack front page deal… thought it could be helpful here as well:

I've bought into the KASA ecosphere pretty heavily, and unfortunately it seems to be true that TP-LINK is phasing out Kasa. All signs point to them expanding their TAPO line and killing Kasa. I've stopped buying their products until TP-LINK starts being more transparent with their plans for the Kasa brand.

At CES last year, TP-link announced plans to get Kasa to work with Apple HomeKit. They've since announced they've cancelled that, and brought ZERO new products to CES 2022 under the Kasa banner… only TAPO branded devices.

The theory is that Kasa markdowns will be more frequent in US to sell off inventory before making the brand announcement here.

There are reports of manufacturers/retailers getting notices of "discontinued without replacement" on Kasa products.

For those who commented about energy monitoring - so what do you do with that info?

when you know how much energy an appliance uses - what does constant monitoring tell you?

I remember a product call 'kill-a-watt' that people would buy and plug it in temporarily for a few days or whatever to get a trend on how much energy does an appliance uses but what's the advantage/need to monitor energy on an ongoing basis?

Just learning about this stuff so thought to ask. - thank you

wow !!
I have deployed well over a couple of hundred kasa plugs to friends, coworkers, family, neighbors and even at my own house. I need to stop recommending these products if what you said here is true.

I originally got into the Energy Monitoring models to prove to my landlord that I wasn't using $250+/mo in Electric (I was closer to $80), because he was fixated on the idea that my 2 computers were somehow using 2500W 24/7. (my meter was shared with 2 other apartments). After showing him 1 month of data, one of the other tenants suddenly moved out in the middle of the night.

Now, I'm using them to show my housemate how much of the electric bill is actually mine.

I use it to automate alerting when the washing machine is done by monitoring the power drop through Hubitat.

I use these daily and so far so good they work as they should and the App is pretty decent. Cheap way to add automation for Christmas light or dust till dawn or Security.

Some examples...most times the requirement will show up once you have it in hand and you will keep seeing the need when you have it with you.
Keep whole house heater turned down. Use only space heater for the one room that needs heat. Measure space heater usage for the month with the Kasa. Sum of utility (gas or oil) heat bill plus electricity bill for the month will help decide if I need to reverse this course and instead keep the whole house warmer and use the space heater lesser. Optimize the cost for getting the same amount of heat from different sources. Of course there is oil/gas/electric unit price variation depending on market conditions, but if you make an worksheet with all variables you can better optimize.
Also would help to understand personal usage patterns like leave on the PC throughout the day versus set it to go to sleep after few hours of inactivity....how much does it really save for electricity.
Sometimes if an appliance is using too much energy and the same task can be done by another lighter appliance then we could switch to that. For instance I used to use the shopvac a lot but when I found its energy usage was very high, I stopped using it as much. I still use it for tasks that really need it but for lighter tasks just use a Dyson or lesser powered vac

I use a Kasa smart plug to control our pond pump, which is rated at 15A. The Kasa plug I have is the 15A model that does energy monitoring, though. Can't remember the model, but I think I've had it for almost 3 years.
sure you've heard this before, but inductive loads like motors, aren't the same as resistive loads like lights or heaters. There'a big inrush of current when the motor first starts turning that might exceed the 15amps.

There are some smart plugs that are specifically rated for motors, and will usually have an amp and a horsepower of the pump rating asts well.

if it's working then keep using it, just check it every now and then i'd say

I'm new to the whole smart house world. Only WIFI is via cell hotspot so data is an issue. How much bandwidth to these require?

That is, how much data would one such plug require in a month? Thank you.

How do you account for communal use like refrigerator/kitchen appliances, hot water heater, HVAC, etc? Seems those would account for a substantial portion of consumption, unless you're measuring your roommate's usage as well?

I have a fridge that gets temperamental and ices up periodically. By watching the energy use I can tell when it has iced up internally.

he was there for two months before me, and established his baseline for electric and gas bills. We'll know how much electric is directly mine, and can guesstimate how much additional electric is used by comparing this month's bill to December.
