And gone the light! This is the natural exclamation in the first moments after the blackout. But what happens to our home smart in the event of a power outage? We will be able to do all those basic operations in order to continue to live in the house without turning it into a trap?
In another article, we addressed the problem of lack of internet connection be overcome, however, thanks to the presence of electrical energy. But here we speak of a sudden event that basically there cut off from the rest of the world. Let’s see what will be the problems to be addressed. First of all, don’t panic.
We start from the assumption that the smart home is not equipped with a UPS, the particular device that goes off exactly in the moment in which there is a loss of electricity and allow the operation of the device to which it is connected. Basically it is an auxiliary generator of energy that works with the battery installed inside and delivers the current network for a given time interval.
Very useful in the case where it is connected to a personal computer, it avoids the loss of data or damage to hardware, allowing the operation even without mains. Removed this case study, in which we talk, a device’s content and all in all not too expensive, fast-forward an entire house with an auxiliary generator, means to spend a lot and have an autonomy is still low. So let’s see what happens to all the amenities of a home smart, when “jumping” the light.
Alarm system, video surveillance, video intercom, and various sensors
The first indication of the blackout is just one of the sirens of the alarms begin to sound in unison. This is because they incorporate a battery inside them that is able to feed them when you stop the electricity of the network, by “reading” the event as a possible intrusion is generated by the malicious who has deliberately cut off the electricity to the house. All the rest of the plant will be completely excluded because the sensors, wired or wireless, will not be able to communicate with the ecu. Needless to say, we will not receive any notification on our app, unless the system is not equipped with a device that is GSM with a buffer battery.
In this case we will receive an SMS with the message of the current outage, or attempted intrusion into the house. Same fate for all of the video surveillance system will remain completely in the dark in all senses, and will not be able to record any activity, and for the video that will remain silent. For all the other sensors that generally live in our home, such as flooding or against the carbon monoxide, are likely to continue to operate, given that in most cases are powered by batteries, and will issue a local alarm, without notifying us, however, on our app remotely. No problem with the door locks smart or typically the elettrocomandate. Fortunately they are equipped with a manual command through the key and let us still go freely from the house.
Thermostat, boiler, valves, intelligent, heat pump and air conditioners
The system of heating, if the boiler is powered by gas, it stops totally working. Why? Trivially, all today’s boilers are more and more equipped by electronic systems of control that no current may not work. In addition, the pump for the water circulation system, also electricity, will stop working. Same destiny for the system of climate control and for all the thermostats environmental connected. In a few words, it remains in the cold or warm, just depends upon the season in which you experience the blackout.
Lighting, shutters and skylights motorized
Needless to say, the lighting jumps of all, less than have emergency lights that are activated instantaneously in the moment in which it breaks the grid. There are many types, even with the size of the plates of the switches. It is a good system, with limited costs, which allows you to have a minimum of lighting available. When the blackout occurs in the evening hours, we are literally in the dark, and move in the house is not always safe.
For all the devices connected to the shutters or skylights motorized, without electricity will stop working and you will have to act manually. Usually these devices motorised are fitted with a release system of the engine that allows the use of the manual. A little like what happens to the electric gatewhich is operated manually by releasing the mechanism using a key or a lever provided.
Electrical appliances, outlets, smart and intelligent assistants
Here you get the peace of mind. Refrigerator, oven, dishwasher or all of the small appliances, will not be able to function. Even the stove, if induction, you will not even make a coffee in the waiting of restoring of energy. Also the taken smart, with all of their technology, will be useless. The only things working will be the radio to the battery that will give us a hand to understand, through the news on what happened to the electricity network and hobs, gas-powered, provided that you turn on the stove with the classic match, because the piezo ignition will not be available. Finally, the intelligent assistants. To the question, “Alexa, when the return current?”, we will not receive any response.
