EVE Announced the HomeKit-compatible Bluetooth Range Extender

Eve system announced an amazing new a few days ago that the Bluetooth range extender compatible with Apple HomeKit will be launched to home automation market in September. This reported detail for Eve Extend noted it is created to solve the problem of Bluetooth signal for HomeKit home hub, to make HomeKit users that can't connect Wi-Fi receive the Eve or HomeKit instruction via the Wi-Fi network and transmit via strong Bluetooth signal.

For Bluetooth HomeKit accessories who need a mobile device to control, like iPhone, iPad or Apple TV, this means they require a wider Bluetooth range. This time, Eve extend is ready to help you enhance the limited Bluetooth signal for more controlled devices that required a strong signal.

Eve Extend can be connected to your Eve devices through a power outlet controlled by Wi-Fi network, and work with up to 8 Eve devices together. Among all devices it can be made the best use of Eve Aqua mostly, which nearly of its application is outdoor and is far away from a home hub or your iPhone. You can place Eve Extend in anywhere within Wi-Fi network. For HomeKit users, this unit is absolute one solid choice to connect more than one Eve Bluetooth devices furthermore, additional Eve Extends are capable of adding to your Wi-Fi network.

It cannot be denied that Eve Extend exerts a significantly positive influence for Bluetooth HomeKit devices, which also brings much benefits for HomeKit devices. But a disadvantage is that the transmission speed is slower than Wi-Fi and Zigbee. Speaking of here, naturally, other wireless technology comes to your mind, like Wi-Fi, Zigbee, LAN and Z-wave. With the wireless technology being introduced, it maybe an overwhelming task for you to decide what kinds of wireless technology your devices use.

This article explain the difference among that types of wireless technology from functionality, data speed and operating range.


This is the most common wireless technology in devices and it is used in devices that lots of us have. Actually Wi-Fi is a direct replacement of the wired Ethernet cable, both of them is used in the same condition in order to prevent a plethora of wires in your home. It provides network connectivity using radio frequency and operate on 2.4GHz or 5GHz frequency and using IEEE 802.11 standards. Through connecting with a router to create a local network for your devices, which devices can communicate with each other due to the same network. The transmission range of 100-300M will not restrict the distance between you and devices or devices and devices. Plus, the transmission speed is up to 300Mbps, which is quite fast on devices communication, on this feature, other protocol falls behind it but, as with anything in this world, it has cons that is the high power-consumption of 10-50mA. So a constant power supply should be ready when your devices run via Wi-Fi network, or strong batteries for them. In smart switch, this technology is an ideal solution to help control your traditional devices, to get affordable smart devices. Meet SONOFF smart switches and you will close to a smart home with an absolute low-cost and safe way.


Generally, Bluetooth is suitable for point to point device communication. The typical application we are similar with is to transfer data (10-100M) from phones to fixed devices via short distance using short-wavelength UHF radio waves. It can boost the convenience and functionality for portable devices with a simple way to make them communicate with other Bluetooth-enabled devices. The CCM AES-128 encrpytion technology provides high encryption and certification during the process of packing data. Strong stability can be achieved due to the 24-bit CRC (Cyclic Redundancy Check) that ensures extreme stability when you pack. It has a lower power-consumption, just 20mA.


ZigBee is a short-range wireless technology and used for home automation. In the current smart home, Wi-Fi is more popular. ZigBee technology will be a trend in future smart home. Of course, we SONOFF will develop smart products based on ZigBee to bring user experience to next level. It uses the same 2.4GHz carrier frequency with Wi-Fi but consumes very lower power. For example, Compared with Bluetooth and Wi-Fi, ZigBee supports devices to work for 6-month to 2-year in the same power supply (two batteries). And ZigBee mesh network can handle up to about 65000 devices which is twice as many as Bluetooth supports. Great scalability owes to its ability to handle many nodes.


Z-Wave is two-way communication wireless technology and low-power. In addition, it is the only smart home protocol to achieve the communication in corss-brand products. Each Z-Wave devices can work with each another, no matter what brands and backward-campatible versions. Z-Wave devices can communicate point-for-point from 30m to 100m on their own. Due to its ability to hop signals, between each device can easily reach the effective distance up to 180m. The benefit of the protocol is that it can avoid interference with the 2.4GHz frequency band in which Bluetooth and Wi-Fi operate.

What's more, let me discuss what is LAN. LAN is a short form of local area network. Before going into the main topic let me first discuss what is LAN. LAN can be used the situation under no available Wi-Fi network connection. Please keep in mind that it requires the connected devices being the same server with your controllable mobile phone or tablet. Considering that Wi-Fi network is unable to access normally at times, SONOFF designs the LAN mode on almost all smart switches to give users the ability to manage devices in their home without Wi-Fi access.

This above technology maybe just an interim alternative in wireless device communication. 5G new technology has rolled out, and it will probably change the way users perceive wireless devices to switch from ISP routers to in-home mobile 5G network. All we do is waiting for its arrival.
