New low-cost solution for smart lighting? First experience of Tuya Beacon smart light bulb

On July 3, Tuya Smart officially launched the Tuya Beacon solution.

1. The distribution network of Tuya Beacon smart bulbs is the same as that of Tuya smart ordinary WiFi lights.
After the light bulb is in hand, it will enter the pairing mode by default when it is powered on. At this time, the light will flash in a cycle of one second. At this time, you can add devices in the "Auto Discovery" of the APP.
On the device details page of the APP, functions such as brightness adjustment, color temperature adjustment, color light adjustment, lighting scene, music rhythm, countdown, group control, and local timing can be realized.
After using it, I personally feel that the operation on the APP and the response of the lights are relatively smooth.
However, it lacks some of the experience of WiFi smart light bulbs. It feels more like using a remote control. The switches are made of two buttons, and the current switch status of the lights cannot be confirmed on the APP page.
According to the official introduction of Tuya, the Beacon Bluetooth physical remote control and gateway solution will be launched in the future.

2. A preliminary study of Tuya Beacon technology

If you want to understand the technical solution of Tuya Beacon, you must first talk about what BLE Beacon (Bluetooth low energy beacon) is (Tuya Beacon is based on BLE Beacon).

Beacon is a broadcast protocol based on the Bluetooth low energy protocol.

Broadcast a data packet to the surrounding (channels 37, 38, 39) at regular intervals. When the Bluetooth host (such as a mobile phone, etc.) performs the scanning action, it will receive the data packets broadcast by Beacon at intervals.
The usage scenarios of Bluetooth Beacon in life generally include:

(1) Advertisement. For example, it is combined with WeChat Shake to do Offline To Online marketing; it is deployed in merchant stores to send coupons and red envelopes;

(2) Push. For example, you can push the bus information of the station at the bus station; when you are close to the artwork in the museum, push the detailed information of the specific artwork;

(3) Indoor guidance and positioning of shopping malls, as well as specific location reminders, item positioning tracking and management;

(4) Sensor applications, etc.;

3. What are the advantages of Tuya Beacon?
If the long-term experience of the bulbs of the Tuya Beacon solution is no different from that of the bulbs using WiFi and Bluetooth, then the price is very advantageous.

So why is the price of this smart light bulb so low? Mainly, the relatively cheap AK801 chip is used on the main control chip
At present, there is no quotation for the AK801 chip, but according to the quotation of an AK802 chip, it is estimated that the AK801 chip should be around 1 yuan.

Because AK801 and AK802 only have the difference of storage space and memory size (AK801 is 4Kx32Bit OTP + 2K Byte RAM, AK802 is 2Kx32Bit OTP + 1K Byte RAM)
