How to know if you can connect an appliance to a smart plug

Avatar of Thomas Grimm



Smart plugs are one of the most affordable, easy-to-use and effective solutions to save on your electricity bill, whether they are standard models or with electricity consumption metering or not. They are also a cheap way to make certain “dumb” devices connected (although with quite a few limitations, as we will see later). Yes indeed, smart plugs are not a panacea: they do not make sense in all devices, nor are they useful and what is more, on some occasions their placement can even be dangerous.

If you’re not sure when to use an electrical outletin this article we help you discover it and choose which devices are the ideal candidates to place one in front of them.

Of amperages and powers

First of all, it is important to know that smart plugs require a ground connection. Although by law this security measure is implemented in current buildings, if you live in an old house you might not have it.

Apart from important issues such as its compatibility with ecosystems, designs and functions, the usual thing in the technical sheets of a smart plug is that it details what it is. the maximum current intensity tolerated. Or failing that, the maximum power of the device that we are going to connect to it.

Actually, you can get the other from one, given that the power is the product of the intensity times the voltage (in this case, the domestic 230V).

Potencia (W) = voltaje (V) x intensidad(A)

The usual thing is that the intensity range supported by smart plugs is between 10 and 16 Amps. Now take a look at the power of the appliance (as before, you will find it on the appliance’s technical data sheet, or if not, on the plug) that you are going to place on the other side.

In some cases, for example with small devices that we know consume little like the fan, there is no failure. But if they are devices that we suspect they are powerful, for example the heating, the hob or the oven, yes. Be careful not to confuse which are the most powerful devices with the appliances that use the most electricity.

We see it better with an example. One of the smart plugs that I have in my house (and that I have used for years to optimize the operating time of my previous electric heater) is the Xiaomi Mi Smart Power Plug (12.39 euros).

Xiaomi GMR4015GL – Power Strip

According to its specifications, its operation is designed for a voltage range of 220 – 240 V, a maximum intensity of 16 A and a maximum power of 3680 W. Now if I want to connect this 30L 1200W electric water heater to the other side, for example, I will be able to do so without endangering the plug and other elements of the installation.


In case of doubt and if the appliance that you are going to place on the other side is expensive, do not play it. Or consult a second opinion, that of the manufacturer’s technical service.

Using smart plugs is one of the best solutions to save with your electric water heater: seven recommended models

Does it make sense to put a smart plug?

Although it is true that by attaching a smart plug to an appliance we can perform tasks such as monitoring its consumption (obviously, the plug must have this function) and turning it off and on to avoid stand byin practice we are adding one more device to the electrical installation that will always be activated and that also consumes, with which Maybe the cure is worse than the disease. In general it is not a good idea, but you can always find out how much the devices consume in standby and do the math.

Also, keep in mind that placing a smart plug or a traditional power strip before a TV is interesting to reduce phantom consumption, but that some models of televisions make compensation cycles (for example, LG OLEDs, after 4 hours of use, they stay “on” refreshing the panel to avoid burning). In the same way, there are devices to which turn them off rennet not the best in the world.


I have calculated how much it costs me to leave the equipment and appliances at home on standby, and I have had an unpleasant surprise

The usual functions of a smart plug usually include programming, in some cases a mode away which in practice consists of allowing the current to pass so that what is on the other side lights up randomly (this is ideal for a lamp, for example, so that it simulates that there is someone at home) and of course, the basics, which is allow current to pass or not pass to the other side so that it reaches the device placed on the other side.

And now that? It depends. In practice, we can only take real advantage of it if the device that is at the exit has simple mechanical controllers, such as a switch, physical buttons, or a spinner. No tactile buttons, displays or similar. And today even the most basic electric coffee makers are ditching the classic switch in favor of more sophisticated controls.

Three perfect examples where to place a plug connected (they are not the only ones): the classic nightstand lamp, the Christmas tree lights and the fan that you see on these lines, which is mine. Just leave the button with speed 1 pressed so that, after connecting to a smart plug, you can turn it off and on at your convenience. Of course, if I want to change speed I will have to get up.

LG’s technology that mixed plasma and LED

Avatar of Thomas Grimm

From 1997 to a good part of the first decade of the 2000s, plasma televisions conquered the high end for a long time. It was the most coveted technology when the user wanted to opt for a panel with the best image quality during that time. However, as we already mentioned in our article about these televisions, the LCD was little by little eating the toastsince its technology was evolving by leaps and bounds.

One of the most noticeable advantages of the LCD was also its lower electrical consumption, thus generating less heat and increasing its useful life. LG wanted to continue betting heavily on plasma televisions, although the manufacturer had to solve the problem of consumption and other aspects if they did not want to abandon the technology. This is how PLED panels were born in 2012.

PLED, an exclusive LG plasma vitamin

PLED comes from the acronym in English Pixel Light Emitting Display. According to the company, this technology brought the best of plasma and the best of LED televisionscombining both Technologys to try to offer a higher image quality, also drastically reducing power consumption at LCD panel values ​​at the time.

When used, a PLED panel is like a vitaminized plasma panel. That is why it is good to remember how plasma panels work to explain their differences. And it is that the screen of a plasma television is formed by two layers of glass between which there are small cells with Xenon and Neon gas which, when excited by an electrical impulse, become plasma, causing the internal phosphor coating of the cell to glow.

What the PLED panel does compared to the plasma is reduce those cells, making each subpixel in a separate cell. This causes the gases to be at a much higher concentration. The cells also contain a denser layer of phosphor.

2023 is going to be a spectacular year in televisions: this is what the main manufacturers are preparing

This concentration means that much less electrical energy is needed to generate the plasma inside each cell. In this way the first advantages of PLED: Its electrical consumption is less than that of conventional plasma and is quite close to what LCD televisions consume.

By consuming less, it also generates less heat and its wear is less. Put at maximum power, a plasma television lasts around 50,000 hours before it starts to degrade. This figure is usually prorated with respect to what would be normal domestic consumption. The resulting figure is about 100,000 hours, which is the figure we all know.


In the case of pledthe highest concentration of Xenon and phosphor increases its useful life up to 80,000 hours of extreme use (as in an airport panel, for example) or 160,000 in a home.


Another of the advantages that PLED continues to maintain from plasma televisions are its self-emissive LEDs. In this way, each pixel can be turned on and off without being subjected to backlighting from a panel of LEDs on the back of the TV. This technology is similar to OLED, although they are not organic LED diodes.

This advantage makes PLED and plasma have better contrast than an LED panel. However, PLED also has an advantage over plasma: its screen is completely matte, reducing the reflection that can be generated by any point of light in the environment. And it is that by the very nature of plasma panels, its glass must always be bright. Sometimes this glare was reduced with anti-reflective coatings, but this diminished the glare emanating from the panel.

PLED also shares the advantages of LED panels

Although we are clear that PLED is like a kind of ‘super plasma’, this technology also includes characteristics of LED televisions, such as electronic image processing, this being the same as that of an LED panel. This eliminates the ‘motion blur’ sensation of plasma TVs in high-speed images, since like LED technology, PLEDs also have three image processors that interleave frames.


Despite the reduction in consumption, PLED screens continued to consume slightly more than LCD panels. In addition, they share the same problem as plasma screens: the ‘burn’ effect when playing still images for a long time.

The OLED was peeking around the corner

Although it was a great advance over plasma panels, the technology did not fully catch on. In addition, they were presented in a context in which the OLED was taking more and more shape (although they were still very expensive to produce) and LCD-LED panels were much cheaper to produce. In addition, with these Technologys the use of elements such as phosphorus and gases was completely eliminated, depending more and more on electronic and digital processing.

In fact, if you asked LG at the time what panels were going to be the future, the company was quick to respond with OLED. And indeed, today it is the technology in which LG has bet the most in recent years.

A couple of years ago Movistar decided to include in its Movistar Plus+ on-demand television platform a series of applications called Living Apps, which allow enjoy different services and content.

They’re available without having to download them from any application store and accessible directly from the decoder menu as long as we have a UHD or UHD Smart WiFi model.

Now the operator has decided expand your collection of Living Apps with a new one focused on decoration and style in the home, for which it has opted for IKEA as a specialist in this type of task.

An app to bring IKEA experts to your TV


The app is already available in Movistar Plus+ and according to those responsible, it is designed to “inspire you with the best accessories and decoration fashions for this new season”

To do this, once we have accessed by first going to the main menucoming into “Apps” and subsequently looking for the “IKEA”we will be shown content related to furniture and decoration with interior design trends, tricks to give old furniture another life and varied content to prepare the home for the changes of season.


Although for the moment the contents are not very abundant, presumably they will add more over time, there will be Live videos with brand professionalsa chat where you can ask questions and you can even buy different products directly from the decoder by scanning a QR code on the mobile.


For example, within the IKEA Living App there are sections like “Always Something New” where it is possible to know the new products of the manufacturer for this new season, “IKEA Wellness”a space that they say is designed to enhance comfort at home and “Homes with Psychology”seven episodes dedicated to specific rooms in the house.


There are also other sections for DIY lovers such as “Decorating Ideas and Advice”, Ready in a Pis Pas”with tips for organizing the environment or “Easy Tricks” to get the most out of the rooms.

In addition, through the section “IKEA Live”it is possible to access their shopping events broadcast live in streaming starring interior designers in their establishments that will also be available later to see them deferred whenever we want.

so you can configure this useful help

Although our star use is to set timers, music or ask for the time and time, you can ask Alexa for many more things, some as useful as serving as a guardian in your day-to-day life: perhaps if you have left a tap running, if it the washing machine or dishwasher has finished. If you did not know or are not very sure how to make Alexa act on beeps or water, keep reading.

A little over a year ago, Amazon added a series of most useful improvements and functionalities for the home: the audible and in-person detection capabilities. Specifically, we refer to this pair of algorithms:

  • Water Running or running water detection. Thus, by listening to the environment, it is able to find out if there is water running around the equipment, for example because we have left a tap open or because there is a leak.
  • Appliance Beeping Detection. In this case, it refers to the ability of the assistant to listen to the different beeps produced by your electrical appliances when they finish their functions, thus allowing us to act accordingly.

What happens at that moment? If you have developed the corresponding routine, you will receive a message on your mobile. In the first case, it is also possible to program a notice that warns that we are spending more water than normal brushing our teeth, for example. The second is especially useful with household appliances that do not have to be smart, such as microwaves, ovens, refrigerators. So, if you leave the fridge open, Alexa will tell you goat.

How to configure these functions

To benefit from these functions it is necessary to go to the section of the Alexa routines from the application. There you can configure the routine you want so that Alexa executes automatic actions for daily milestones, for example, that the washing machine program has finished.


In the Amazon Alexa application, tap on Further, which you will find in the lower right corner. There select routines and click on the “+” in the upper right corner to create a new Routine.

Alexa 2

There are four steps. The first is to name it. After in “When” Choose “sound detection“. Within that option you will see both options beyond the beep or the water such as snoring, crying baby, coughing or barking dog that can give you new ideas, for example a lullaby sounds when your little one cries. Then choose which device and in what time range. Finally you will have to add the action you want. So, if you want it to reach your mobile, choose “Notification” (yes, you will have to have the notifications of said application activated). However, in “alexa says” You could also choose what the Amazon voice assistant’s response would be by simply typing it in “Custom”.
