preface
It has been done before Project 2: DHT11 access to Xiaoai students as well as Item 3: air conditioning control The next step is to combine the two to realize app control, temperature and humidity viewing, and simple air conditioning control for Xiaoai.
Didi: the following is the main body of this article
Idea:
Realize app + Xiaoai dual control
Disguise the equipment as a lamp (let Xiao AI define our equipment as a lamp), and then customize the lamp mode function to realize multi-state control of air conditioning.

Official sample file
You can see the following mode functions from the above data. What we need to do is magic change them!
void miotMode(uint8_t mode)
{
BLINKER_LOG("need set mode: ", mode);
if (mode == BLINKER_CMD_MIOT_DAY) {
// Your mode function
}
else if (mode == BLINKER_CMD_MIOT_NIGHT) {
// Your mode function
}
else if (mode == BLINKER_CMD_MIOT_COLOR) {
// Your mode function
}
else if (mode == BLINKER_CMD_MIOT_WARMTH) {
// Your mode function
}
else if (mode == BLINKER_CMD_MIOT_TV) {
// Your mode function
}
else if (mode == BLINKER_CMD_MIOT_READING) {
// Your mode function
}
else if (mode == BLINKER_CMD_MIOT_COMPUTER) {
// Your mode function
}
wsMode = mode;
BlinkerMIOT.mode(mode);
BlinkerMIOT.print();
}
Blinker_APP equipment configuration:
Then the air conditioning controller equipment of the previous project was changed to add new components and realize more functions
The configuration code is as follows:

Then, wiring shall be carried out according to the pin of the board corresponding to the GPIO defined by the code:
As shown in the figure:
Infrared module: data pin connected to D5 (GPIO14)
DHT11 module: data pin connected to D2 (GPIO4)
Just find the positive and negative pins and connect the 3v and G (grounding) on the board
Xiaoai training & Testing
After uploading the code, enter the MI home and synchronize the device:
You can see that the app already has data
Then we will train Xiao AI's classmates:
Training is configured according to the actual situation of the mode function you define. You only need to train the wake-up word, and then select the execute action
The custom name here is the air conditioning controller. In fact, Xiaoai defines the light equipment to control different air conditioning states according to the last mode
hey!
The last is the test
The wake-up word here is: turn on the dormitory air conditioner
PS: all the effects have been achieved. It's too cumbersome to record the video. It's not difficult to improve the air conditioning control based on the last project. It's just a little imperfect. Xiaoai can't read the temperature and humidity and can only view it on the app. DIY device Xiaoai can only be defined as one device type, and Blinker official only provides five device types for free users, But it's enough. Nice
summary
Basically improved, the functions you want, the next thing to consider is a set of applicable power supply scheme, as well as optimizing code and reducing power consumption. After all, most Internet of things devices focus on low power consumption!
emmm, it rained all day today, and the weather turned much cooler. It seems that you can't use the air conditioner. Gee, forget it. I'd better believe in the weather in Guangdong! ╮(╯﹏╰)╭Project directory:
