Introduction
This guide covers the process of using Rule Machine, Hubitat’s automation engine to modify a device’s internal configuration parameters based on a schedule.
This is particularly useful for tasks like dimming the LED indicators on smart switches at night or changing the sensitivity of motion sensors during specific hours.
Prerequisites
Device Driver Support: Ensure you have the Inovelli drivers installed (manually or with Hubitat Package Manager) as the Inovelli device drivers support the
setParametercommand. Most community drivers and advanced built-in drivers include this.Parameter Details: You will need the Parameter Number and the Value you wish to set. These are usually found in the device's manual or the manufacturer's online documentation.
Step-by-Step Configuration
1. Create a New Rule
Navigate to the Apps tab on your Hubitat dashboard.
Open Rule Machine and select Create New Rule.
Give your rule a descriptive name (e.g., "Change the default level local Ceiling Light Nightime").
2. Define the Trigger (The "When")
Click on Trigger Events and select the type of trigger you wish to use.
Select Time of Day from the capability dropdown.
Choose your desired time (e.g., "At a certain time" like 8:00 PM, or "Sunset").
Click Done with Trigger Events.
3. Define the Action (The "What")
Since Change Parameter isn't a standard command like On or Off, we will use the Run Custom Action feature.
Click Actions to Run.
Then
Select Set Mode, Variables or File, Run Custom Action.
Select Run Custom Action.
Select capability for action: Choose the capability of your device (usually Switch, Dimmer or Actuator).
Select devices to add to action: Pick the specific device you want to modify.
Select custom command: Look for
setParameter.Note: If
setParameterisn't there, the driver may not support manual overrides via Rule Machine.
Add Parameter(s): You will need to add two parameters the parameter number and the value
Parameter 1: Parameter Number (Integer)
Then enter parameter number (in the example it is 13 and click done with parameter
Parameter 2: Value (Integer), add parameter select parameter type and integer value for the dim level 50 (50%), on (1) or off(0), etc.
Click Done with Action, then Done with Actions.
