Management of all smart home devices through the communication channels of Bluetooth
Most of all, in the market of wireless smart home control systems, between them there is an unspoken competition, who will provide more functionality and who will be the best in the end. Recently modified Bluetooth system from Bluetooth SIG has shown quite decent performance in order to become a leader in the segment.
Bluetooth SIG is a company that is mainly engaged in the polarization and development of Bluetooth standard. The company`s engineers have modified their" standard " to the level of Bluetooth mesh. The essence of the theme in the broad development of communication management systems based on the Bluetooth standard. Bluetooth mesh network is built on the principle of each node is connected to each nearest. This scenario of setting the network can be easily applied in the implementation of control systems "Smart home". Everything in a smart home can be done on a chain. For example, you open the front door, the lock gives a signal to turn on the light in the corridor as soon as you find yourself in the corridor, then turn on the light in the hallway, if it is dark and your favorite radio and so on along the chain. Such a network is quite possible to build, it will work stably, because all the devices in it do not consume much energy. Energy savings occur at the data transfer level. Instead, to give a signal through three walls in the room to switch on the light, lock gives a signal to the lamp bulb in another lamp, and so on the chain is almost without barriers small irradiating electromagnetic field.
The system "Bluetooth mesh" is designed for a wide range of devices and does not assume that at some point in time all the devices work. Some devices in the network can be battery operated and can be used as repeaters for short periods of time, the same as permanently powered devices may be of a different, higher priority and, accordingly, the entire system from this configuration becomes more economical in terms of consumption and environment. Batteries of some devices are used only to receive the signal and their charge is enough for months of operation. The signal came and the air conditioner worked according to the previously installed program or the signal came and the automatic vacuum cleaner started according to the program. And it can be run through the sensor reflected laser beam. If a lot of dust on the floor, then the system is turned on, if there is no dust at the level, not involved. You can run the system with reference to hours and days, as anyone wants, and implements the launch of the system along the chain. All messages exchanged between devices are encrypted, so you can intercept them, but it is not so easy to fake a message from outside.
Apparently, not all devices will receive updates to the new standard, some do not change, but the system is developing and it is already positive. Bluetooth device mesh can be installed in any smart home in which any device to communicate in the Bluetooth standard 4.0 or 5.0. On the one hand, there is no need to buy some additional equipment to expand the functionality, and on the other hand the network config is built so that it can be rebuilt at least every day in order to get some more tangible effect of economy and speed. If a device is broken, it`s easier to replace on new, fast to integrate and not bother diverse repairs and service centers. If you believe the developer of the standard, it will be used within six months after its announcement. For some devices the update is released and any that do not have to. The system is built so that some devices can even communicate with smartphones over the Internet. So that you can control the air conditioning and lighting even being at a great distance from home. So this standard continues to develop, you need a minimum of manufacturers to ensure that useful devices in this standard as much as possible. It is also desirable when installing the network to see examples of usage and examples of construction of networks for smart home. It is also important to add that Bluetooth is not quite what it used to be, stability has been added, the reception quality has improved, so that this method of communication can already be trusted. Bluetooth not trying to replace the Wi Fi, it is better for the reason that the signal is an order of magnitude less background radiation in a smart home below...
