In order to read value use the <b><i>status</i></b> command:
In order to read values, use the <b><i>status</i></b> command:
ubus call ioman.gpio.dio0 status
ubus call ioman.gpio.dio0 status
ubus call ioman.relay.relay0 status
ubus call ioman.relay.relay0 status
To change input settings use the <i><b>update</i></b> command and specify a value:
To change input settings, use the <i><b>update</i></b> command and specify a value:
ubus call ioman.gpio.dio0 update '{"value":"0"}'
ubus call ioman.gpio.dio0 update '{"value":"0"}'
ubus call ioman.gpio.dio0 update '{"value":"1"}'
ubus call ioman.gpio.dio0 update '{"value":"1"}'
To change relay settings use yhr <i><b>update</i></b> command and specify a state:
To change relay settings, use the <i><b>update</i></b> command and specify a state:
ubus call ioman.relay.relay0 update '{"state":"open"}'
ubus call ioman.relay.relay0 update '{"state":"open"}'
iio (isolated input) input 1021 (to read value refer to gpio1021)
iio (isolated input) input 1021 (to read value refer to gpio1021)
In order to read digital input value use the <b><i>cat</i></b> command:
In order to read digital input values, use the <b><i>cat</i></b> command:
cat /sys/class/gpio/gpio14/value
cat /sys/class/gpio/gpio14/value
cat /sys/class/gpio/gpio1021/value
cat /sys/class/gpio/gpio1021/value
To change an input state usethe <b><i>echo</i></b> command (where "1" is "dry" state and "0" is "wet" state):
To change an input state, use the <b><i>echo</i></b> command (where "1" is "dry" state and "0" is "wet" state):
echo 0 > /sys/class/gpio/gpio12/value
echo 0 > /sys/class/gpio/gpio12/value
echo 1 > /sys/class/gpio/gpio38/value
echo 1 > /sys/class/gpio/gpio38/value
When one Relay output is open, the other one is closed, so to turn an output on or off, you will have to change value on both pins:
When one Relay output is open, the other one is closed; so to turn an output on or off, you will have to change the value on both pins:
echo 1 > /sys/class/gpio/gpio20/value & echo 0 > /sys/class/gpio/gpio22/value
echo 1 > /sys/class/gpio/gpio20/value & echo 0 > /sys/class/gpio/gpio22/value

In order to read one-wire sensor data you will need to follow these steps:
