Note: With older releases DHT22, AM20302, and AM2321 sensors operated under ``AM2302 (3)``. They now operate under ``AM2301 (2)``. If you are using a DHT22 or similar and do not see ``AM2302 (3)`` use ``AM2301 (2)``.
You can add a sensor using the following (MQTT) commands:
1. ``modules`` - show supported modules
2. ``module 4`` - select desired module functionality for a Sonoff TH (Wait for the restart)
3. ``gpios`` - show supported sensor types. (DHT21 = AM2301, AM2302 = AM2321 = DHT22)
3. ``gpios`` - show supported sensor types. (e.g. DHT21 = AM2301)
4. ``gpio`` - show current defined sensors on supported GPIO pins
5. ``gpio14 2`` - select sensor AM2301 (Wait for the restart)
For some sensors to show up a power cycle of Sonoff is needed to reset the devices just configured.
## I2C sensor
The following I2C sensors are supported using ``I2C SCL (5)`` and ``I2C SDA (6)`` in group 3:

## Additional Configuration
### Temperature Units
The temperature units can be set to report in Fahrenheit with the command:
``SetOption8 1``
to set back to Celsius use:
``SetOption8 0``
### Update Interval
To change the update interval change the ``TelePeriod``. The default interval is 300 seconds. The interval can be set between 10 and 3600 seconds. To set the update interval to 10 seconds, so the sensor will update 6 times a minute use the command:
``TelePeriod 10``
