===1-Wire activation commands===
In order to read one-wire sensor data you will need to follow these steps:
<ol>
<li>Set one-wire sensor value to "1' using the <i>ubus</i> command: <pre>ubus call ioman.gpio.onewire update '{"value":"1"}'</pre></li>
<li>List the connected one-wire devices from the <i>/sys/bus/w1/devices</i> directory using the <b><i>ls</i></b> command: <pre>ls /sys/bus/w1/devices</pre></li>
<li>Choose a sensor to read and obtain its state from the <i>/sys/bus/w1/devices/<device_name>/w1_slave</i> directory: <pre>cat /sys/bus/w1/devices/<device_name>/w1_slave</pre></li>
</ol>
