Regarding the core connection device in the home smart home system such as 3.0 gateway, many people are confused and have no clue about what it is, what it is, how to choose when they first come into contact with smart homes and want to connect various smart gadgets at home! Simply put, the 3.0 gateway is like a bridge between various smart devices that support protocols – such as lights, switches, sensors, and the wireless network at home, that is, WiFi, which builds a bridge specifically for message transmission, translation, and running errands. It can collect the signals sent by those devices and convert them into "words" that our mobile phones or routers can understand. In this way, we can use the mobile app to control those devices, and those devices can also report their status information, such as whether the light is on or off, or the temperature is over.
1. The power of compatibility : The most powerful thing about 3.0 gateway is that it is stronger than the old version or other gateways with some messy protocols, which is its compatibility! It is like a hospitality owner, compatible with almost all third-party equipment that meets the 3.0 standard. No matter which brand of light bulb or which manufacturer's door lock, as long as they carry a 3.0 "id card" on them, they can "friendly shake hands" with this gateway and work together in most cases, so we don't have to worry about the problem of "never interacting with each other" between the equipment.
2. Transmission distance and network stability : 3.0 uses the technology called "Mesh Ad Hoc Network". What does it mean? That is to say, the gateway and the device, as well as the device and the device, can help each other transmit signals! In this way, even if any device is a little far away from the gateway, the signal may not be very good, and it can "jump" through other devices in the middle to pass the signal over. Therefore, the entire wireless signal coverage has greatly increased. In general, in a house with a house of 100 to 200 square meters, under normal circumstances, a gateway can run very far and smoothly, and the network will not be disconnected at any time, which makes people angry.
3. Benefits of low power consumption : The protocol itself is particularly power-saving, which is a blessing for devices such as battery-powered sensors! As their "master" of the gateways, when communicating with these devices, they will also "save effort" and will not eat up a lot of power at any time. This means that small things like human body infrared sensors and door and window magnetic sensors can be used for a long time after changing the battery, and some can even be used for a year or two without worrying about it, saving us the trouble of always thinking about changing the battery.
Many friends have asked, what should I pay attention to when choosing a 3.0 gateway? Don't worry, listen to me slowly tell you some real tips that can help you:
First, look at what equipment you already have or want to buy at home : You have to think about what equipment you already have at home and what brand they are from? Or what types do you plan to buy in the future? Although 3.0 is compatible, sometimes some brands may still make some of their own "thinks" and make something slightly more special, and confirm in advance whether the gateway supports these devices, so that they can avoid many detours!
Official data and actual experience of the number of connected devices : Generally, gateway product introductions say how many devices it can connect, such as 30, 50 or more. but! Don't just look at the number, the difference may be quite big when used. If you are a "smart device control" and have a lot of things at home, try to choose products with a large number of official nominal connections and a good reputation among users.
A small test of signal coverage capability : If conditions permit, you can ask the seller if there is a trial policy, or check out the sharing of other users on the Internet. In the location where you plan to put the gateway at your home, simply test whether the equipment can connect and respond stably in every corner of the house, especially those equipment hiding in the cabinet or behind the wall.
Whether the supporting APP is easy to use is also very important : the gateway generally needs to be set up and managed with a mobile APP. Is the interface design of the APP messy and ugly? Is the operation intuitive, simple or not? Incomplete functions? These will directly affect the mood and convenience of our use, and cannot be ignored.
A user master asked, "I already have a WiFi smart device at home. Do I still need to buy a 3.0 gateway?" Hahaha, this score depends on it. If all the smart devices in your home are connected by WiFi, then maybe doesn’t need it for the time being! However, if you find that WiFi at home is sometimes a bit "overwhelmed" and there will be a bit stuck when there are too many devices; or if you want to buy some small sensors that need to be particularly sensitive and power-saving, the device plus the gateway will definitely make your smart home experience a big step, which will be much more stable and save a lot of power, really! Provide global procurement services for weak current intelligent products! Someone asked: "Can 3.0 gateways of different brands be mutually compatible?" Theoretically, if they all meet the 3.0 standard, the underlying communication can be understood by each other. However, in order to better control the experience of their own products, manufacturers may restrict the APP and some advanced functions – so it is completely universal, without any problems at all, and sometimes it may be a little troublesome.
I personally think that for friends who want to build a stable, efficient and worry-free smart home system, choosing a reliable 3.0 gateway is definitely a cost-effective and wise investment. It may not allow you to see changes all at once like a smart light bulb, but it works silently behind it to ensure the smooth operation of the entire system. This "invisible" value will be found to be indispensable after you get used to it!
