-There is a single command that may be used for resetting all pins to INPUT with the weak internal pull-up resistor DISABLED as follows:
+The behaviour of all pins on the MCP23008/MCP23017 can be reset to a specific setting/mode globally to simplify the initial configuration as follows
 
-`sensor29 reset`
+```
+sensor29 reset    // Reset all pins INPUT, no interrupt, no pull-up by default
+sensor29 reset1   // Reset all pins INPUT, no interrupt, no pull-up by default
+sensor29 reset2   // Reset all pins INT on CHANGE, with pull-up enabled by default
+sensor29 reset3   // Reset all pins INT on LOW, with pull-up enabled by default
+sensor29 reset4   // Reset all pins INT on HIGH, with pull-up enabled by default
+```
 
-This will be confirmed by a response like this - note the 99's indicated in each value to differentiate it from other MQTT responses
+The command will respond with confirmation as follows:
 
-`MQT: stat/sonoff/RESULT = {"Sensor29":{"D":99,"MODE":99,"PULL-UP":99,"STATE":99}}`
+`MQT: stat/sonoff/RESULT = {"Sensor29":{"D":99,"MODE":pinmode,"PULL-UP":pullup,"STATE":99}}`
 
-You may also query the existing configuration for a particular pin using
+Pin and State is reported as 99 because it was implemented accross all pins.
 
-`sensor29 pin,?`
+Mode should correspond with the reset pinmode option used.
 
-For example:
+Internal pull-up resistors on the MCP23008/MCP23017 is disabled by default for pin mode 0 whilst enabled by default for pin modes 2 through 4.
+
+If specific pins require specific configuration after this command has been issued the pins may individually be configured using:
+
+`sensor29 pin,pinmode,pullup`
+
+The usage of the above is described in more detail further in this page.
+
+The configuration of a specific pin may be queried using command:
 
 `sensor29 0,?`
