Adding new Module types

Before you add a new module type, you can try using the module type "Generic" over the web interface and set up the GPIO Config.

Generic Module was added in v5.12.0, before that version its called "Wemos D1 Mini".

Check the Other Devices Page for more infos and other Devices with ESP.

Module types are defined in sonoff_template.h

This includes a "User Test" module type that you can experiment with

You can add an additional type by editing both the mytmplt and module_t arrays to add your own module type (make sure you keep the order of entries in the two arrays the same)

The module definition is a list that contains the module name, followed by a definition of what each of the 17 GPIO pins on the ESP-8266 are defined to be. Each item in the list can be either 0 (unused), or a pin definition from the list below.

As of 3/9/17 (4.0.3) these functions are:

* GPIO_DHT11,          // DHT11
* GPIO_DHT21,          // DHT21, AM2301
* GPIO_DHT22,          // DHT22, AM2302, AM2321
* GPIO_DSB,            // Single wire DS18B20 or DS18S20
* GPIO_I2C_SCL,        // I2C SCL
* GPIO_I2C_SDA,        // I2C SDA
* GPIO_WS2812,         // WS2812 Led string
* GPIO_IRSEND,         // IR remote
* GPIO_SWT1,           // User connected external switches
* GPIO_SWT2,
* GPIO_SWT3,
* GPIO_SWT4,
* GPIO_KEY1,           // Button usually connected to GPIO0
* GPIO_KEY2,
* GPIO_KEY3,
* GPIO_KEY4,
* GPIO_REL1,           // Relays (0 = off, 1 = on)
* GPIO_REL2,
* GPIO_REL3,
* GPIO_REL4,
* GPIO_REL1_INV,       // Relays with inverted signal control (0 = on, 1 = off)
* GPIO_REL2_INV,
* GPIO_REL3_INV,
* GPIO_REL4_INV,
* GPIO_LED1,           // Leds (0 = off, 1 = on)
* GPIO_LED2,
* GPIO_LED3,
* GPIO_LED4,
* GPIO_LED1_INV,       // Leds with inverted signal control (0 = on, 1 = off)
* GPIO_LED2_INV,
* GPIO_LED3_INV,
* GPIO_LED4_INV
* GPIO_PWM1,           // Warm
* GPIO_PWM2,           // Red (swapped with Blue from original)
* GPIO_PWM3,           // Green
* GPIO_PWM4,           // Blue (swapped with Red from original)
* GPIO_RXD,            // Serial interface
* GPIO_TXD,            // Serial interface
* GPIO_HLW_SEL,        // HLW8012 Sel output (Sonoff Pow)
* GPIO_HLW_CF1,        // HLW8012 CF1 voltage / current (Sonoff Pow)
* GPIO_HLW_CF,         // HLW8012 CF power (Sonoff Pow)
* GPIO_USER            // User configurable

The online user can only change GPIO functionality for pins that are defined as GPIO_USER in the module.
