History of mijia hub

History of mijia hub 

This article dynamically updated the history version of Xiaomi's mijia Gateway in order to better select the gateway; The reason is that I am playing smart home and HA, and it took a long time to sort it out and use it for reference.

Some customers also asked which gateway to choose the BLE mesh protocol or the Zigbee protocol to make the solution.

Xiaomi Mijia Gateway version history

It is only for reference when purchasing Xiaomi gateway.

Separate gateway name

The same gateway is called by various names at home and abroad, and consumers are confused about which gateway it is, so I call it gen X generation in chronological order

Xiaomi multifunctional gateway. It is a green rice OEM, but it is based on the standards given by Xiaomi (except for the hub gateway - matter is coming, Xiaomi is in the layout?). ）。

Xiaomi separate Bluetooth gateway。

Bluetooth gateways are generally integrated into various smart devices

Supported networking methods

Support 5.8GHz/5.1GHz/2.4GHz wireless LAN
Wired to the Internet

Supported sub-device protocols

ble mesh

For the sub-devices that are accessed, say the following:

1. Only BLE Mesh is supported
2. Zigbee is not supported

2. It is understood as a router with Bluetooth function. Theoretically, the hub gateway is higher than the multi-mode gateway and the previous level of smart audio, and it does achieve local automation across gateway devices, including ZigBee devices under multi-mode gateways, and ZigBee devices under M1S cannot be used for the time being.

The problem is that cross-gateway device linkage is often triggered by bedroom equipment to trigger long-distance linkage such as living room equipment, and the advantages of localized low latency are not felt.

3. In the past, the equipment connected by Xiaoai Audio Pro could only be automated in the cloud, and now it can be local. This point is praised, but I don't understand that Xiaoai Audio Pro is already a quad-core A53, which is similar to the configuration of the hub gateway, much stronger than the multi-mode gateway, why not directly achieve localization on the audio?

4. Automation that cannot be local before, such as: including scene switches, including light groups, including certain WiFi devices, can not be localized. It doesn't represent as many advantages over multimode gateway configurations at all.

5. When connected to the wired network, the Bluetooth signal is very strong, but it cannot penetrate two load-bearing walls.

6. Replace the built-in Bluetooth mesh gateway of Xiaoai speaker with weak performance before

7. Enable the whole house smart home terminal to achieve localized execution and obtain the same smart home experience as Zigbee devices.

Actual usage

1. I am an ordinary smart product user, the number is not much, but there are quite a lot of varieties involved. With the use of the hub gateway, the current feeling is also: stability should be improved, localization conditions are a bit harsh, and the advantages of multi-mode gateway are not obvious. There is a feeling of buying a loneliness

Bluetooth, in addition to the low cost of the module, and must go around the server to cultivate user brand stickiness, I think there is no advantage over zigbee

There are many names for the versions on the Internet:

Xiaomi Hub 2, Xiaomi Mijia Smart Multi-Mode Gateway 2, Xiaomi Smart Home Hub 2, DMWG03LM, ZNDMWG04LM

Articles at home and abroad on the Internet call the gateways of Xiaomi, Mijia, Lumi, and Yeelight Xiaomi gateways for a while, and Yeelight mesh gateways for a while. So consumers are confused.

There are various versions of the Mi gateway.

all the hubs are made by Lumi, but are released with different mijia brand names, but the difference is not just the brand name.

If you still can't figure it out after reading this article, you can contact me. Find your own contact information.

I follow these principles to classfiy the relationship between brands.

Mijia - the gateway to Xiaomi's own brand home.

Lumi, Yeelight(Yilai) gateway etc.- the gateway of Xiaomi ecological chain cooperation company.

This article describes

Mijia - the gateway to Xiaomi's own home

Correct a misunderstanding

Smart home device access, must have a gateway, who said that such and such a device does not need a gateway?

In fact, the WiFi protocol router is also a gateway, which should be called a WiFI gateway. It's just that I have it at home.

Integrate the router into zigbee, Bluetooth ,Bluetooth Mesh, isn't it a multi-mode gateway?

Purchase principles

Electronics, buy new and not buy old

Xiaomi's things do not need crowdfunding, just wait for PDD, and it won't be long before the price is cheaper than crowdfunding

Gateway classification by protocol

To select a gateway, the protocol must be selected;

In fact, the router of the WiFi protocol is also a gateway, called a WiFI gateway.

Therefore, if smart devices want to enter the network, they must buy a gateway (who said on the Internet that such and such a device does not need a gateway, but the user has a router at home, which makes a group of consumers confused).

WiFi gateway (router)

One is called Bluetooth gateway,

One is called Bluetooth mesh gateway,

One is called a zigbee gateway.

One is called Zigbee mesh gateway

Infrared gateway

The following are used more abroad

Thread gateway

Zwave gateway

Copy

Mijia gateway selection scheme (by protocol)

Mijia's gateways currently include: Bluetooth gateway, Bluetooth mesh gateway, Zigbee gateway, infrared gateway

One is called Bluetooth gateway (such as: Mijia smart socket 2 Bluetooth gateway version)

One is called Bluetooth mesh gateway (such as: Mijia hub gateway, Yeelight gateway-non-Mijia)

One is called multi-mode gateway (such as: Mijia multi-mode gateway 2, which supports WiFi, Zigbee, and BLE Mesh)

One is called Zigbee gateway (non-mesh networking) - represented by aqara - non-Mijia

Warm reminder

Bluetooth gateways are different from Bluetooth mesh gateways, and Bluetooth gateways can only receive information reported by sub-devices; The Bluetooth mesh gateway can not only receive the information reported by the sub-device, but also send control information to the sub-device.

Therefore: Mijia smart socket 2 Bluetooth gateway version, after connecting with mobile phone Bluetooth, can send command control.

Mijia gateway selection scheme (divided by networking structure)

20220722 updated

At present, Mijia gateways are divided into three categories:

Hub gateway

From the gateway

Blind gateway.
