Lighting timers allow you to automatically control lights on and off using preset software settings. Otherwise, such devices are called time relays. Typical examples of use include adjusting the lighting in an aquarium, on a staircase landing, or in a garden plot after sunset. In addition, in any case, this type of smart devices allows you to save energy without human intervention. Lighting timers, as a rule, are a plastic monoblock with a set of buttons for control or a touch screen.
Classification of devices
There are two main types with different operating principles - electronic and electromechanical. In the first case, there is a special microprocessor inside the case that is responsible for processing all commands, and in the second version, reading occurs due to the presence of a mechanism with a synchronous motor powered from the network.
Based on the operating period, lighting timers are divided into the following types:
- daily allowance;
- weekly;
- astronomical;
- universal;
- with countdown;
- with random switching.
The installation method also has several variations, including stationary, mounted in a panel, box, or on a special DIN rail. Classification according to operating conditions divides such devices depending on the degree of protection from external influences and the rated power of consumers that can be connected to the device.
Features of timers on electronic relays
This class is classified as programmable. Commands are entered using a front panel with a certain number of controls such as buttons or a touch screen. The device is powered by a built-in battery or battery.
Among the advantages of this type, it should be noted a large selection of available modifications with interval adjustment of lighting operating modes, many installation and installation options, as well as a good level of performance indicators. Users highly appreciate the sufficient information content of the specified settings on the display, the ability to record their own work in the internal memory of the device and save them even in the absence of power.
Typically, an electronic timer for lighting allows even ultra-short switching ranges of up to one minute to be created. The accuracy of the readings is definitely higher than that of devices with an electromechanical relay.
How to choose
Technical devices from different manufacturers differ in appearance and characteristics. When choosing an outlet with a timer, you need to consider the following points:
- It is imperative to determine the required cycle time range in minimum values.
- The number of cycles over a certain time period. For different models, this indicator can range from daily to weekly.
- Control method. Mechanical instruments are less accurate, but more reliable. Electronic ones are more informative during the work process. All current indicators are displayed on the screen.
- Dimensions. This can be important in limited spaces.
The main voltage indicators for most devices are similar and amount to 16 A. There are devices with autonomous operation, this also needs to be taken into account. If you may need an outlet without access to electricity, then it is worth considering an option with a built-in battery.
Features of timers on electromechanical relays
This variety has only two options for functioning - weekly and daily. The timer can be programmed here using a graduated wheel and several levers. All elements are usually located on the front panel of the device. Lighting timers of this type are either installed permanently in a rail or a special box, or simply plugged into an outlet.
This option should be chosen by those for whom the smallest switching range or setting programs with an accuracy of one second is not so important. With all this, ease of setup for many can be a completely decisive positive argument when choosing. However, low accuracy and possible program failures due to the lack of an additional power source will become the main problems of such a device in the future. In addition, the gear teeth gradually wear out, which will affect the serviceability of the adjustment wheel.
What are plug timers and smart plugs?
The socket timer turns off the power supply to devices literally according to a schedule. It looks like an adapter that plugs into a regular outlet. And the devices whose operation is planned to be controlled are already included in it.
There are many options for smart timers. Some only know how to turn off the power after a certain period of time. Other models can not only turn off the power supply, but also turn it on according to a certain schedule, turn it on and off remotely, and also count the amount of electricity consumed. They are no longer called timers, but smart sockets. And such devices really make routine tasks easier. And this is how they do it.
Working principle and application
The operating principle may depend on the specific type of device. If we consider the controller using an astronomical timer as an example, the essence of its operation is that the readings of the built-in clock are compared with an astronomical table. Information is transmitted to two contact relays. The first of them includes a timer for light, looking only at the device’s own built-in readings. The second relay performs the same functions, but it is also capable of removing the load from the device for a certain time period specified by the user.
Timers for street lighting are widely used in the security sector and emergency lighting of non-residential buildings. Also, such devices are used by summer residents in the areas in front of the house. Advertising agencies install light timers on their own billboards for better display at night or in cloudy weather.
What needs to be done before turning on?
As a first step, it is recommended to select a suitable power supply and connection scheme. If the load values are very large, then it is best to use special contactors. Next, the device is installed in its proper place. A switch is also installed in the lighting control panel. Then, using cables or wires, you need to power the device into the electrical network and connect it to the lamps that it will control.
After all procedures are completed, voltage is applied to the lighting control timer. Experts advise carrying out technical inspections and routine diagnostics at least once every six months. First of all, you should check the reliability of fastening of the device itself, as well as the connections with the elements of the electrical circuit and terminal blocks.
Connection options and order
The device can be powered via three-wire or four-wire electrical networks. Each lighting timer comes with a special adapter for the required quantity. The first circuit allows you to assemble a circuit in which there will be no additional lighting load directly after the switch itself. In the second case, fixtures and lamps will be connected immediately after it.
The connection process is quite simple and does not require any special skills or calling a specialist to your home. You can attach a modular timer, for example, to a DIN rail. This is done using special latches, if any, on the device. This option is only available in the case of a modular design. External buttons are connected based on the previously selected connection diagram to the electrical network.
Contact Features
If powered by three wires, pay attention to their colors. The blue conductor from the outdoor lighting timer is used to connect to zero. Also, if desired, any lighting fixture can be combined with this color. The brown conductor is connected directly to the phase of the electrical network. Red is required to control the sensor. It must be routed to the lamp from the regulator that is available.
Sometimes there is also a fourth wire that acts as a grounding wire. When it is connected, it becomes possible to prevent a voltage drop across the body of the device in advance. The general connection diagram will not change in any way, but the grounding will need to be connected to the lamp itself, bypassing the regulator. In rare cases, manufacturers may change the labeling and, accordingly, the set of colors. Then you will need to carefully study the installation and operating instructions supplied with the device.
Xiaomi power timer: what is it
These days, gadgets can turn on, turn off, and even perform some actions on their own. And the reviewed power timer is no exception.
The power timer is an ability to regulate the phone's energy consumption by turning it on and off according to a schedule.
The greatest energy consumption occurs when the display is on, so almost all modern devices have the option to turn off the phone or turn off the Xiaomi screen, as well as detailed settings where you can adjust the time the screen turns off (on Xiaomi this is possible after 15 seconds to 10 minutes, more There is a “Do not turn off completely” mode - the screen will remain on until you turn off the phone yourself).
Also with the power timer function - when the phone is running, even if you are not using it, energy is consumed, so you can save it by automatically turning it on and off.
Step-by-step instructions option
The information is relevant for those who decide to attach the device to the wall, which is, in turn, the most common installation option.
- Almost always, on the body of the lighting switch-off timer there is a diagram for connecting the device to the electrical network. It is necessary to study it carefully.
- The second step is to choose the optimal location for the device. Recommendations are given for each device separately. In addition, the main options are outlined above.
- In accordance with the diagram on the device, it is necessary to connect the wires to the lighting device that you plan to control.
- The fourth step is to configure the device itself. The program is set according to personal preferences. The convenience and accuracy of the settings will depend on the type of timer chosen.
- If remote elements come with sensors, they must be connected using wires.
Automatically turn Xiaomi on and off: how to set it up
There are two ways to configure this option, however, they are almost the same - one is a little longer.
- How to set up your Mi Band 3 via the MiFit app
Attention! The function of automatically turning your phone on and off is only available on phones running Android 4.0 and higher.
Tips for connecting
Installing and configuring lighting timers involves a number of specific nuances, the most important of which are given in the list below.
- If several lamps are planned in the system, then without a special controller they will not be able to work correctly. This element will be located in the circuit between the timer itself and the lighting fixtures.
- The power characteristics of the temporary relay must correspond to those output by the network. Otherwise, there is a high chance of fire or damage to the device.
- Each device can be connected in different ways. The most appropriate one should be determined at the purchase stage.
- If the sensor is based on the light level, then its response limit should be adjusted. The default level is usually set to 5 lux. This way the light will turn on before it gets dark outside.
- This system can be successfully combined with motion sensors and other elements for security and warning.

Quite a popular model with high build quality and a decent manufacturer’s warranty. You can purchase the model on the Russian market for 1,300 rubles .
The issue of energy saving
For outdoor lighting, there are two main methods that allow for more practical use of resources. The first of them is the use of special lamps with greater luminous efficiency or lamps with a higher level of efficiency. The second option involves customizing existing equipment. Proper control of the lighting switch-off timer is the key to saving energy. Experts recommend a mode in which the light is on after sunset and when people are moving around the area, and during periods of no movement or after sunrise, the device remains inactive.
Using the Power Timer
As mentioned above, this option can be used at night to save energy.
If you are at study, work, doing important things and don’t want to be distracted by anything or to have your phone’s energy wasted, activate the function of automatically turning your gadget on and off by specifying the desired days of the week and time.
There are situations when Xiaomi's automatic shutdown is used for safety purposes if the smartphone gets very hot at night (this can happen when the phone is placed under a pillow or blanket). Or so that nothing happens to it while you are away - the gadget can be “programmed” in advance for a specific day of your departure.
