I tried to visualize the power consumption of my house with Nature Remo E lite
Introduction
Using "Nature Remo E lite" that can acquire the amount of electricity used at home in real time,
I made a dashboard that visualizes power consumption
By displaying the usage status of the air conditioner acquired by Nature Remo,
** You can see the relationship between power consumption and air conditioner On-Off at a glance! ** **
I feel that we have taken a step forward toward the realization of an energy-saving house.
IoT and smart meters
It's been a long time since the word ** IoT ** became a boom, At the same time, the difficulty of creating value with IoT is becoming more widespread, and I feel that the world's eyes on IoT are becoming stricter.
The figure below is the 2019 version of the "Hype Cycle Diagram" announced by Gartner.
The IoT has entered a period of disillusionment.
Especially for home-use IoT products, except for smart speakers and smart remote controls, which are predominant in the world, I feel that there are many things that do not seem to have much merit even if they are made smarter.
Under these circumstances, the IoT product that electric power companies are steadily introducing is ** smart meters **. If we can visualize and efficiently use power consumption, which is a major cost for homes and society, It is based on the idea that ** "value" ** can be created.
What is Nature Remo E lite?
The above smart meter transmits power consumption data using a wireless standard called WiSUN, This data can also be received and used by third-party products (B-root service).
Of these third-party products The ** power consumption data receiving device ** developed by Nature, which is famous for its smart remote controller "Nature Remo",
** Nature Remo E lite **.
What you can do
With Nature Remo E lite, you can:
・ Check power consumption with the app
With the official app, you can check the current power consumption and a simple history graph
・ Acquisition of power consumption data by API
Power consumption data can be handled programmatically using the API. Basically, it can be obtained from API common to Nature Remo.
GET /1/appliances
With the command, you can get the power consumption data of Remo E lite as well as the device data of Nature Remo.
API execution example
Type the following command on Linux ([Click here for access token issuance method](https://qiita.com/t-chi/items/01b9a9b98fbccef880c3#natureremo%E3%81%AE%E3%82%A2%E3%82%AF % E3% 82% BB% E3% 82% B9% E3% 83% 88% E3% 83% BC% E3% 82% AF% E3% 83% B3% E3% 82% 92% E7% 99% BA% E8 % A1% 8C% E3% 81% 99% E3% 82% 8B))

Information on smart meters "smart_meter": You can find it in the "val" in the "echonetlite_properties" section. The two sections below are of particular importance.
normal_direction_cumulative_electric_energy: Total power consumption so far (unit: 0.01kWh)
measured_instantaneous: Current power consumption (unit: Watt)
In the case of the above JSON, the total power consumption is 2942.63kWh and the current power consumption is 464Watt.
- Please note that the section contents may change due to the update of Remo E lite.
** This time, we will use this API to display the relationship between power consumption and air conditioner On-Off in a graph as shown in the top image **
Things necessary
** ・ Nature Remo E lite ** ** ・ Normal Nature Remo ** ‥ Required to obtain on-off information for air conditioners ** ・ Raspberry Pi ** (Raspberry Pi3 Model B is used this time) **-Python execution environment ** (preset Python 3.7.3 is used this time) ** ・ Google account ** (required to use spreadsheet & data portal)
procedure
Follow the steps below to create a power consumption dashboard.
** 1. Apply for B route service to the electric power company 2. Nature Remo E lite initial settings 3. Building a logging system with Raspberry Pi 4. Creating a power consumption dashboard **
1. Apply for B route service to the electric power company
In order to obtain smart meter data, you need to apply for B route service to your electric power company. (Even if you are using a service like au Denki for electricity liberalization, you need to apply to an area power company like TEPCO.)
Apply from the electric power company homepage
In my case, I applied from the Kansai Electric Power Group website below. https://www.kansai-td.co.jp/application/smart-meter/low-pressure/index.html
For other power company areas, please refer to the following https://chasuke.com/nremoe/
When I applied, I received a phone call and said that simple construction (free of charge) was required, so the flow was to adjust the schedule and then carry out the construction.
Whether or not construction is necessary depends on the smart meter installation status of the house. As of 2020, about two-thirds of households nationwide are becoming smart meters. ・ For households that are not smart meters, you can apply for replacement with priority when applying above. ・ Even if it is a smart meter, additional work may be required like me. It seems.
B Root service ID and password received
When the above application and construction are completed, the electric power company will send you the B route service ID and password by mail. At TEPCO, the password is sent by e-mail, and the sending method seems to differ depending on the area (in any case, I think it is either e-mail or mail).
2. Nature Remo E lite initial settings
Plug the Nature Remo E lite into an electrical outlet
Plug the Nature Remo E lite into an electrical outlet.
I felt that plugging it into an outlet close to the switchboard would often work better when synchronizing later.
Download the Nature Remo app
Download the app from the site below to your smartphone and install it. android iOS
Initial setting
Basically, proceed with the initial settings according to the instructions of the application, If you are asked for an ID and password on the way, enter the contents mailed from the electric power company.
Sometimes it fails when syncing with meter or WiFi, but I In the case of, it often worked if I tried again several times.
3. Building a logging system with Raspberry Pi
The previously developed sensor data logging system will be used. First of all, please carry out the contents of this article (it is long, but I would appreciate it if you could associate with me)
This time, in order to make the above system compatible with Nature Remo E lite, You need to rewrite remo.py and sensors_to_spreadsheet.py. Please rewrite each as follows. (It corresponds to the operation to incorporate the JSON returned in the above [API execution example] into the logging target)

Other than making it possible to acquire Remo E lite data, we have made some improvements, but I think that it is a level that you do not have to worry about in actual operation.
Also, if the configuration file DeviceList.csv contains NatureRemo's (API_URL and Token must be entered), No new additions are required for Remo E lite.
When you start logging with cron, as shown in the red frame below,
Device name_CumulativeEnergy: Total power consumption (unit: kWh)
Device name_Watt: Current power consumption (unit: Watt)
Two types of fields are added.
You can see that the power consumption increases at once when the air conditioner is turned on. In the next chapter, let's graph this situation.
4. Creating a power consumption dashboard
Google Data Portal is a dashboard that can be edited and viewed on the cloud. Use this tool to create a dashboard that shows the relationship between power consumption and air conditioner on-off.
Creating a new report
** Specify Google Spreadsheet as the data connection destination **
** If you are asked for approval, press the approval button **
** You will be asked for the referenced sheet, so specify the spreadsheet created in ④ **
** Press "Add to Report" **
** Rename the report **
Creating a daily power consumption graph
Create a graph to see long-term changes
** Click Resources → Manage Added Data Sources **
** Click "Edit" for the target data source **
** Change the date and time to a recognizable format ** (The data portal has a strict date and time recognition format)
If you want to get the correct statistics such as average: YYYYMMDD
If you want to display the measured value for each line: YYYYMMDDhhmm
** Add a field (field for power consumption calculation) **
** Set the fields as shown below (power consumption maximum value-minimum value ≒ power consumption of the day) **
- (Count + 1) / Count is multiplied because the first power consumption of the day cannot be added, so that amount is approximately added.
** Return to the main screen and click on the graph to change to a time series graph **
** Specify the dimension (horizontal axis = Date_Master_Day) and index (vertical axis = Diff_CumlativeEnergy created above) **
** Change the index name to "Daily power consumption (kWh)" **
** Change to hide missing values **
Creation of instantaneous power consumption & air conditioner comparison graph
Create a graph comparing the power consumption (Watt) measured every 5 minutes with the air conditioner On-Off
Creating an instantaneous power consumption graph
** Specify the dimension (horizontal axis = Date_Master) and index (vertical axis = device name_Watt) **
** Specify the date range to be displayed (in the figure below, from 0:00 two days ago to 24:00 on the day) **
Addition of air conditioner on-off information
** Click Resources → Manage Added Data Sources **
** Click "Edit" for the target data source **
** Create a field "Aircon_On" that represents the on-off of the air conditioner as shown in the figure below **
** Add "Aircon_On" to the same graph as Instantaneous Power Consumption **
** Change missing values to linearly interpolate **
** Adjust the display color of the graph **
Adjusting the entire graph
Adjust the overall layout from "Themes and Layouts"
Add a graph to your liking → Display the required numbers on the scorecard,
It looks better
- To display "Current power consumption", it is necessary to add the data of "Current" sheet in the spreadsheet.
** That's it! ** **
in conclusion
As you can see, the power consumption of the air conditioner is tremendous (when it is turned on, the power consumption more than doubles ...) In addition, it seems that the power consumption is the highest immediately after it is turned on, and when the power consumption gradually decreases and drops to a certain level, it becomes sick.
** TV and light bulb ON-OFF information ** can also be obtained with API, so After adding these, let's look at the relationship with power consumption.
I want to create "value" by reducing electricity bills without ending with visualization! Aim! ** Energy saving house! ** **
