Power Minute Average sensor updating at 4 minute intervals

[michaelsleen]

I am using this Emporia Vue integration in an automation to alert me when the clothes dryer is done based on sensor.dryer_3_1min also known as the Power Minute Average. The automation is triggered when sensor.dryer_3_1min is above 1 for 1 minute, and then waits for sensor.dryer_3_1min to go below 1 for 2 minutes 5 seconds, since it appeared that HA logs sensor.dryer_3_1min updates in History exactly every 2 minutes. However, sometimes the interval stretches to 4 minutes, resulting in a false alert that the clothes dryer is done. Below I highlighted the 4 minute interval, whereas the rest are 2 minute intervals.

Any idea why the interval time would be inconsistent, and if there is a way to standardize (ideally every 1 minute)?

Firmware: Vue2-631

The clothes dryer is not working non-stop, but in several cycles. My automation waits for the power to be zero for 10 minutes before it triggers. Here is an example of a cycle and then a brake and then another new load later on.
