Confirmed-COV Traffic

Overview

• There’s too much threshold in the Change of Value (COV).
• For example, when the lights turn on, there’s a response back saying the lights turned on. Or, the temperature fluctuates by a certain amount, and a notification gets sent.
• Have to send back that you received the Change of Value.
• It’s a configuration issue that can create a lot of traffic.

Why it fails

• Configuration issue, where the value has increments that are too small. E.g. Change of Value should be 2° instead of 0.001°.
• Leftover commissioning trend logs.
• Getting Confirmed-COVs for irrelevant changes. E.g. a confirmation on temperature, or lighting. Usually you want a Confirmed COV with outputs, not inputs.

How to fix it

• Find the device that’s sending out too many COVs, and reconfigure the device.
• Change the increments.
• Evaluate if Confirmed-COV is needed.
