    MOES WiFi Smart Temperature and Humidity Switch Module MS-103

    Core Model:WB3S
    This device has three LEDs, a button, and two relays, as well as a 1-Wire sensor interface that supports two types of sensors: the DS18D20 temperature sensor and the CHT8305 temperature and humidity sensor, both using a 1-Wire connection and not I2C. The button controls the on/off state of the two relays, and automatic temperature and humidity control can be set up using Tuya's Smart Life app, making it ideal for various temperature control scenarios. However, it should be noted that the maximum current for the relays is 10A, so the load device should not exceed this limit without taking appropriate measures. Currently, the only drawback of using the OpenBeken platform is that it does not support 1-Wire devices. Below are the GPIO definitions for the WB3S chip.

    “pins”: {
    “1”: “Btn;0”,
    “6”: “Rel;1”,
    “7”: “1-Wire;0”, #TO DS18D20 OR AM2301A
    “8”: “LED_n;1”,
    “9”: “LED_n;0”,
    “10”: “WifiLED_n;0”,
    “24”: “Rel;0”
    },

    Thank you, I will try to get that 1 wire working soon. I can easily buy DS18D20 with donation funds. Thanks.

    I will also attach here an interesting screenshot from the sale offer of this device:

    Hello
    I am in the process of flashing this device with Tasmota. I have a model with only a temperature sensor. In this case, will it be possible to configure pin 7 to read only the temperature, omitting the one-wire protocol? What value should then be at pin 7?

    It depends on what temperature sensor you have and what communication protocol it supports. Write more information about your device and sensor.

    We have progress on DS18B20 driver. Most of sensors should work. More fixes soon. DS18B20 should work with OBK these days.

Topic summary

The MOES WiFi Smart Temperature and Humidity Switch Module MS-103 features a core model of WB3S and supports two types of sensors via a 1-Wire interface: the DS18B20 temperature sensor and the CHT8305 temperature and humidity sensor. Users can control the device through a button that manages two relays, with a maximum current of 10A. The device can be configured for automatic temperature and humidity control using the Tuya Smart Life app. Discussions include efforts to flash the device with Tasmota firmware, inquiries about pin configurations, and updates on driver compatibility for the DS18B20 sensor. A template for the device's firmware has been shared, detailing its specifications and pin assignments.
