How To Avoid Spikes In Sensor Readings Caused By EMI

To set the delay in RoomAlert.com:

Please follow the instructions in this Frequently Asked Question: How To Delay Actions In Your RoomAlert.com Account.

We recommend setting a delay of 5 minutes, the shortest option available at RoomAlert.com. You’ll need to delay each action associated with your alert.

To set the delay through Room Alert Manager:

1. Open Room Alert Manager. For instructions, please see our FAQ, How to Open Room Alert Manager’s Web Interface.
2. In the navigation bar to the left, select Alerts.
3. Locate the alert that you wish to delay. From that alert’s menu, select Edit.
4. In the Then… section of the alert form, change the DO THIS selection from immediately to after X seconds.
5. Enter a number of second that is higher than Room Alert Manager’s Data Polling Interval.
   By doing this, Room Alert Manager will wait to trigger the alarm until it reaches that number of seconds.
6. Select Save Changes to save your action delay.

For example, if the refresh rate for Room Alert Manager is 15 seconds, you can set the action to start after to 40 seconds. Room Alert Manager will be checking 3 times—once at 0, 15, and 30 seconds—for a sensor value that is above the alert threshold. In this time, any spikes will come and go, and Room Alert Manager will not trigger an alert because the quick spike did not sustain the elevated threshold for longer than 40 seconds.
