This occurs with a number of our devices. Is this something that should be reported as a problem? What is the explanation behind this?
This can happen with devices that are ON but have cycling power usage, e.g. an oven, once through pre-heat or a dishwasher as different parts do their thing while the appliance is ON
However if it’s something like an HVAC fan that’s clearly on, using continous power, but is showing on & off, something else is happening that needs investigation. Shoot an e-mail to firstname.lastname@example.org, with screenshots etc.
