The software allows for dynamically configuration of sensors and devices to selected GPIO pins. Depending on the type of (Sonoff) Module certain GPIO pins are easily accessable.
The software allows for dynamically configuration of sensors and devices to selected GPIO pins. Depending on the type of (Sonoff) Module certain GPIO pins are easily accessible.
Sensor configuration is possible by either the web pages OR using the commands ``modules``, ``module``, ``gpios`` and ``gpio``.
The software supports:
- [single wire sensors](#single-wire-sensor)
- [dual wire or I2C sensors](#i2c-sensor)
- [dual wire or I<sup>2</sup>C sensors](#i2c-sensor)
- [single wire devices](#device)
Only one sensor per group is allowed.

You can add I<sup>2</sup>C sensors using the following (MQTT) commands:
1. ``modules`` - show supported modules
2. ``module 1`` - select desired module functionality for a Sonoff Basic (Wait for the restart)
3. ``gpios`` - show supported sensor types. We need two pins: I2C SCL (5) and I2C SDA (6)

4. ``gpio`` - show current defined sensors on supported GPIO pins

The software will autodetect the connected I2C devices. For some sensors to show up a power cycle of Sonoff is needed to reset the devices just configured.
