11/1 Update:
Added Q&A at the end of this article: Q1: Why the energy cost is not calculating correctly? 

Hey Tapo Users! We have all-round upgraded the energy monitoring function feature in the Tapo app for you. As energy prices soar these days, we are all seeking ways to save on our electric bills. Tapo new Energy Monitoring 2.0 offers an opportunity to better understand and optimize your energy consumption.


To use the new Energy Monitoring, the following conditions should be met

1. Supported on model Tapo P110 or Tapo P115 with 1.1.2 and later firmware

2. Tapo App should be upgraded to the latest version 2.10. X.

Note: the firmware is rolled out to Tapo users gradually, not all in once, if you didn't receive this firmware update, kindly wait for another  few days.

New Energy Monitoring Dashboard

The new energy monitoring dashboard contains three core data:

lPower consumption of 'Today':    Display energy consumption of  today from 0:00 to the current time. 
l  Power consumption of 'This Month': Display energy consumption of the past 30 days. 
l  Current power: Refresh real-time power value every 5 seconds.
l Energy Measurement to 0.001 kWh: More decimal place in the energy consumption metric to 0.001Kwh (1W) helps you to view more accurate energy data. 

 

Energy Usage & Power Graphs  

 
With straightforward graphs, you can easily know when your appliances are consuming most power, and how much power they consume at different times. It can also display your power consumption in calendar view.


l  Energy Usage Graph: You can now check your total power consumption by day, month, or year.

① Day: Display the total power consumption of today in the past 24 hours, the minimum time interval is 1 hour.

② Month: Display the power consumption of this month, the minimum time interval is 1 day.

③ Year: Display the power consumption of the past 12 months, the minimum time interval is 1 month.

          


l  Power Graph: You can review the power data at different time during the past day or week.

① Day: Display the power value today from 00:00-24:00, the minimum time interval is 5 minutes.

② Week: Display the power value of the past 7 days, the minimum time interval is 1 hour.

      

Reset Energy Usage Data

l Delete Energy Usage Data : Now you can find an option to reset the energy data to zero  easily without a factory reset.

Energy Calendar:

l Daily Energy usage in a Calendar: Display daily power consumption in the past 3 months and the Monthly electric bill.

l Visualizing electric consumption with colors: Use color of blue, orange and red to represent lower, average and higher scales of electric consumption values.

 




Electric Bill Calculator:


l Bill of past 30 days: Display the accumulated electric bill of past 30 days.  You can iput your electricity rate, to get an estimated cost of the power consumed by each connected device. Tapo app has Singular Billing or Periodic Billing two types of billing.

 

Note:
1. the price unit by default is consistent with the unit of the Tapo Care subscription.
2. Electric Bill in the app provides an estimated cost for reference only, the electricity costs in real world depends on your electric company.


l  When To Use Singular billing:

Select Singular billing if you have a fixed-rate energy plan. Fixed-rate means that the price you pay per kilowatt-hour (kWh) stays the same throughout your usage.

Calculation formula:  bill of this month= (electricity rate per kWh) x (total energy consumption of this month).


  


l  When To Use Periodic billing

Select Periodic billing if you have a variable-rate energy plan. Variable-rate means that the price you pay per kilowatt-hour (kWh) could go up or down in a day or different seasons of a year. 

You can set variable electricity rates by Winter and Summer , Workday and weekends, Peak and Off-peak hours.
 

 

① Winter and summer

1. Summer  (customizable): May 1st – Oct. 31th

2. Winter (customizable): Nov. 1st –  April 30th 

3. Customize time range

 


② Workdays and weekends

 


③ A day divided into 3 periods: off-peak, mid-peak, peak.
Calculation formula: bill of this month = (peak hours x peak hour price)+ (mid-peak hour x mid-peak hour price)+ (off-peak hours x off-peak price)



     



Tapo Power Protection 


l Power Sensing as Trigger: you can set Auto Power Off for the connected device when its power exceeds your customized threshold. This feature can help to protect your electronics and prevent fire accidents caused by electrical overload.

l  Customized threshold: You can manually set threshold by dragging the scroll bar left and right.

Adjustable range:1W-3670W
Minimum adjustment unit:10W

l Notification reminder: When plug detects overload, it will turn off automatically and send a push notification to your mobile device.

  
Frequently Asked Questions

Q1: Why the energy cost is not calculating correctly? 

It is possible that electricity rate was ever changed in the Electric Bill settings: 
The new electricity rate will only be applied to the new-generated energy consumption (kWh) afterwards, the previous data still use the old electricity rate.  

If the electricity rate has been changed, the formula to calculate your electricity bill is : 
Cost = (kilowatt-hours)  x (Old electricity rate)+ (kilowatt-hours) x ( New electricity rate)

[Troubleshooting Tips ]

Try to reset energy usage data and test the Bill function again: 
1. Reset energy data in the app
2. Select Singular Bill
3. Input the Electricity rate *pay attention not change the price during test
4. Check if the Cost of follow the formula: (kilowatt-hours) of this month x electricity rate
