Port Assignment - Assigning Hardware Ports to Sensors/Equipment
From the Home screen, press: Settings > Hardware
> Port Assignments, and you will see the PORT
ASSIGNMENTS screen, at left, where you can
customize some of the ports for different sensors
and equipment. Overtime more options will be
available here as more equipment is added and
verified. When you use these ports be sure to set the
correct sensor type or equipment type.
Port 6-9: is for the 4 spare temperature sensors.
They can be a DS18B20 temperature sensor or
DHT22 temperature/humidity sensor. (Future - add
the option so they can read an analog/digital sensor
as well).
Port 10-13: are the 4 accessory ports. The option selected affects the Ground pins on each of those ports. If “DC Accessory”
is selected the Ground pin is switched on/off via the controller which turns DC accessories on or off. If “Powerhead” is
selected the Ground pin is always turned on, in effect becoming a regular ground pin.
The port has a 12v pin but you can easily use a 6v or 24v external power source if needed. This pin is PWM so it'll also be
able to change the speed of fans, etc. There's also a pin available on each port that can put out a digital or analog signal to
control digital powerheads like the Jebao or Tunze. Technically you can control 12 pieces of equipment on the 4 ports.
Today it will only turn on/off one of the pins on each port using a custom rule but to use that feature you need this option
set to DC Accessory.
Port 14-17: are the 4 other device ports but no settings available, currently you add your flow meters here. Future releases
will add other devices.
Port 18-22: are for the 5 analog sensor ports, currently this options allows you to choose if you’re using a digital sensor or
analog sensor.
*Note: When an analog sensor is checked is reads it 3 times, the last value is stored and the final reading is the most
common number out of 10 readings. This helps smooth out the readings.
