Using the OpenMotics micro CAN modules efficiently

//Using the OpenMotics micro CAN modules efficiently

The micro CAN module is OpenMotics’ latest powerhouse offering multiple features in a small package.
As with most multi functional devices some steps should be taken to ensure its most efficient use.

First, let’s take a look at the specs of the micro CAN module:

  • 6 Inputs
    • Connect up to 6 inputs. An input can be a simple switch, motion detector, any potential free contact, and many more
  • 6 (LED) Outputs
    • Many switches have a built-in feedback LEDs to show the user whether or not the circuit is on or off
  • 2 Sensor connections
    • Either 2 temperature sensors or 1 temperature + humidity sensor

So for a typical use case (e.g. a set of switches on the wall) 1 micro CAN module must be present; even when only 1 of the available inputs is used.
The above would not take full advantage of the capabilities of each device and can be greatly improved by smart placement of the modules.

During the planning phase of the project placement should be chosen so 1 micro CAN can service multiple rooms or locations. Typically, 2 adjacent rooms can use a single micro CAN to fully use its inputs, outputs and temperature sensors.

In terms of cable length between the micro CAN module and the input, output and sensor, the following guidelines should be followed:

  • Connection to the inputs: no maximum cable length
  • Connection to a feedback LED: no maximum cable length
  • Connection to a temperature sensor: cable maximum 1 meter

All OpenMotics CAN modules (CAN Control and micro CAN) are scheduled for release in January 2017.
