This topic describes the no-code development solution of SoC-based infrared (IR) thermostats.
No-code SoC-based IR thermostat
Based on the IR no-code product, this product is equipped with a temperature and humidity sensor. This way, the temperature and humidity changes can be detected in real time. Thus, IR air conditioners can adjust the ambient temperature and humidity accordingly.
Product features
Currently, the following features are available:
-
Perform remote control of devices.
-
Set up scenarios and control the device on/off.
-
Control the IR devices, such as IR air conditioners.
-
Share devices in a home to other users.
-
Achieve the IR learning feature. The data from the original remote control of the appliance is stored in the cloud.
-
Integrate with popular voice assistants, including Amazon Alexa, Google Home, Tmall Genie, Rokid, JD DingDong, Baidu DuerOS, and Tencent Xiaowei.
-
Control the device on/off with local buttons.
-
Display the temperature and humidity data.
-
Prompt the cleaning of filters.
-
Set up the temperature range.
Device panel
To create a product on the Tuya IoT Development Platform, you can select an appropriate panel as you want, and scan the QR code by using the Smart Life app.

Parameter configuration
-
IR channel: IR sending pin and IR learning pin.
-
Pairing: Wi-Fi LED, triggering method for the first pairing, reset button, network light status when unconnected, network light status when networked, and press-and-hold seconds to enter pairing.
-
Multiplexing: It is divided into the following two cases.
- Multiplexing. The power button is also used as the reset button, whereas the status LED is also used as the Wi-Fi LED.
- No multiplexing. The power button and status LED are configured separately.
-
Basic features: Sensor type, I2C clock pin, and I2C data pin.
-
Measuring parameters: Sampling interval, regular reporting interval, temperature threshold, and humidity threshold.
LED status description
| Status | Steady off after pairing by default | Steady on after pairing by default |
|---|---|---|
| Not paired | Steady on | Steady off |
| Ready for pairing (EZ and AP compatible mode) | Blink quickly | Blink quickly |
| Paired (with normal network) | Steady off | Steady on |
| Paired (with network exceptions) | ||
| Paired (send code library data) | ||
| Enter learning mode | Steady on | Steady off |
| Learning mode (the learning code is received) | Steady off | Steady on |
| Exit learning mode | Steady off | Steady on |
| Power indicator (after power-on) | Be on for 5s | Be on for 5s |
| Air conditioner is on | ||
| Air conditioner is off |
The above table shows the multiplexing configuration of the thermostat.
