What are the data refresh rules on the energy monitoring page?
Last Updated on:2023-11-22 03:43:48
When you enter the page of Energy Monitoring, the system will query the current real-time energy parameters of the device and refresh them; if you stay on page, the system will refresh the data every 5 seconds.
If you do not stay on the page, the device will report the data according to the actual situation. In order to avoid circuit interference or frequent reporting due to small-scale fluctuations in the power consumption of the electrical equipment itself, the current voltage threshold is set.
Judgment basis for device reporting
Mechanism
Detection period
Uniform: Long interval: 30s. Short interval: 5s.
If no change is found during the interval, the interval will change into a long one. If it changes, the interval will change into a short one.
Change rate threshold
Voltage change: 2%, or power change: 20% by default.
Current change: Ignored.
Low-power processing mechanism
When the real-time power is less than 20w and the absolute value of the power change exceeds 3w, the data is reported.
