1. Introduction You can monitor the electricity usage of residential electricity system using our wifi usage meter and IAMMETER system. IAMMETER system can generate the electricity bill on daily/monthly basis and also provide the comprehensive report for you to understand your electricity bill and energy consumption easily. 2. Functions 2.1 Overview dashboard View the data graph and some details in overview dashboard. 2.2 Quick view energy consumption and bill View the energy consumption and your electricity bill on the same page for different places Visit Chapter 4.12 for details. 2.3 Set the billing date You can set the billing date so the system will calculate the monthly electricity bill based on the start date you set, if you billing date doesn't start from 1st of each month. Visit Set bill date for details. 2.4 Billing report IAMMETER system can generate electricity billing report for users. Visit Billing Report for details. 2.5 Comprehensive Energy Consumption Analy...

Wifi will enter standby mode when there is no data transmission. There are two situations in this situation: 1. If there is no AP connection, the wifi chip will enter deep sleep. At this moment, it is completely controlled by the master control, and the power consumption is shown as uA level on  wifi power consumption meter . 2. When the AP is connected, the wifi chip will enter the sleep mode, but it will automatically get up to check the data. The wake-up period depends on the DTIM interval of the router AP (this value depends on the AP's ability to cache data). The value of DTIM interval is the interval of n Beacon, which is set to 1 by default. At this point DTIM interval is equal to beacon interval. Generaly speaking, when DTIM is equal to 1, the average current is 1mA. Of course, this value means that in the case of no data transmission and reception, wifi chip continues to sleep when waking up at regular intervals. This is also the most important low power consumption indica...
