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.

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)	No multiplexing: Steady on Multiplexing: Blink slowly	No multiplexing: Steady off Multiplexing: Blink slowly
Paired (send code library data)	No multiplexing: Blink once Multiplexing: No blinking	No multiplexing: Blink once Multiplexing: No blinking
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	No multiplexing: The air conditioner indicator is steady on. Multiplexing: The pairing indicator is steady on when the network is fine. It turns on for 5s and then blinks slowly if the network is not good.	No multiplexing: The air conditioner indicator is steady on. Multiplexing: The pairing indicator is steady off when the network is fine. It turns off for 5s and then blinks slowly if the network is not good.
Air conditioner is off	No multiplexing: The air conditioner indicator is steady off. Multiplexing: The pairing indicator is steady off when the network is fine. It turns off for 5s and then blinks slowly if the network is not good.	No multiplexing: The air conditioner indicator is steady off. Multiplexing: The pairing indicator is steady on when the network is fine. It turns on for 5s and then blinks slowly if the network is not good.

The above table shows the multiplexing configuration of the thermostat.
