Cospa's strongest IoT home appliances! Operate TPLink products from Raspberry Pi
What is TPLink?
A network equipment manufacturer in Shenzhen, China, whose main product is routers. In recent years, we have been focusing on IoT home appliances such as smart light bulbs and smart plugs, and have established a unique position on Amazon due to the good cost performance.

This time, using the API, ・ ON-OFF operation of equipment ・ Acquisition of information such as ON-OFF and light bulb brightness I tried running it in Python and Node.js
Since the above can cover many of the applications that can be thought of as IoT home appliances. ** The result of feeling the possibility of application **!
Things necessary
** ・ PC ** ** ・ Raspberry Pi ** ** ・ TPLink smart plug or light bulb ** This time I tried the following 3 products HS105: Smart plug KL110: White light bulb KL130: Color light bulb
① Confirmation of data acquisition
First, test on the terminal whether the data can be obtained from TPLink.
- Articles that I referred to https://lmjs7.net/blog/tag/tp-link/ https://qiita.com/tmisuoka0423/items/582ff0c303abe8570ee5
Examine the IP
Install tplink-smarthome-api (reference)
sudo npm install -g tplink-smarthome-api
Get a list of connected TPLink devices with the following command
tplink-smarthome-api search
HS105(JP) plug IOT.SMARTPLUGSWITCH 192.168.0.101 9999 B0BE76 ‥ Smart plug
KL110(JP) bulb IOT.SMARTBULB 192.168.0.102 9999 98DAC4 ‥ White light bulb
KL130(JP) bulb IOT.SMARTBULB 192.168.0.103 9999 0C8063 ‥ Color light bulb
You can see that all three devices have been detected
Confirmation of acquisition of device operation information
You can get device settings and OnOff with the following command.
tplink-smarthome-api getSysInfo [IP address of the device]:9999
** ・ Example of KL130 (color bulb) **
：
ctrl_protocols: { name: 'Linkie', version: '1.0' },
↓ Here is the device settings
light_state: {
on_off: 1,
mode: 'normal',
hue: 0,
saturation: 0,
color_temp: 2700,
brightness: 100
},
↑ This is the device setting
is_dimmable: 1,
is_color: 1,
：
on_off: 0 means power off, 1 means power on hue: color? (0 in white mode) color_temp: Color temperature (0 when not in white mode) brightness: Brightness (in%) Seems to be
** ・ Example of KL110 (white light bulb) **
：
ctrl_protocols: { name: 'Linkie', version: '1.0' },
↓ Here is the device settings
light_state: {
on_off: 1,
mode: 'normal',
hue: 0,
saturation: 0,
color_temp: 2700,
brightness: 100
},
↑ This is the device setting
is_dimmable: 1,
is_color: 0,
：
on_off: 0 means power off, 1 means power on hue: Hue (0 in white mode) saturation: saturation color_temp: Color temperature (0 when not in white mode) brightness: Brightness (in%) It seems that. It's almost the same as KL130, but it's not a color, so it seems to be is_color: 0.
** ・ Example of KL105 (smart plug) **
alias: '',
↓ Here is the device settings
relay_state: 1,
on_time: 288,
active_mode: 'none',
feature: 'TIM',
updating: 0,
icon_hash: '',
rssi: -52,
led_off: 0,
longitude_i: 1356352,
latitude_i: 348422,
↑ This is the device setting
hwId: '047D‥',
relay_state: 0 for power off, 1 for power on on_time: Continuous power ON time rssi: WiFi signal strength It seems that. The longitude (logitude) and latitude (latitude) are also displayed, but the mystery deepens when it is 5 km away from the actual location.
Above, you can confirm that you can get the information you want with the command! In the following chapters, we will describe how to get and operate from the program (Node.js & Python).
② Get state with Node.js
** * If you say "I don't need to explain Node.js because I use Python!", Please skip this chapter and move to ③ **
Refer to here and refer to Node.js
Pass the path to npm (for Window)
On Windows, the path does not pass to the global installation destination of npm, and the module can not be loaded with Node.js, so please pass it by referring to the following https://qiita.com/shiftsphere/items/5610f692899796b03f99
Pass the path to npm (for Raspberry Pi)
Find out where to install the npm module globally with the command below (For some reason, it seems to be different from the folder found by the command "npm bin -g" in Windows)
npm ls -g
Edit .profile with the following command.
- In SSH environment, edit .bash_profile instead of .profile
nano /home/[User name]/.profile
Add the following line to the end of the .profile and reboot
export NODE_PATH=[The path examined above]/node_modules
If the path specified by the following command is displayed, it is successful.
printenv NODE_PATH
Creating a node.js script
Create the following script
tplink_test.js
const { Client } = require('tplink-smarthome-api');
const client = new Client();
client.getDevice({ host: '192.168.0.102' }).then(device => {
device.getSysInfo().then(console.log);
});
If you execute the script with the following command, you can get various information in the same way as ①.
node tplink_test.js
- I also created a script that csv logs the above (same function as the Python script in ③), but my JavaScript skill is low and sometimes it does not work well (the processing order of the asynchronous part is reversed), so the code is here Will not be pasted I uploaded it to GitHub below, so please modify it at your own risk and use it. (I hope I'm ignorant and comment on the reason why the processing order is reversed ... I'd be happy if you could laugh) https://github.com/c60evaporator/TPLink_Info_Nodejs
③ Get state with Python
I didn't log well in Node.js due to my lack of JavaScript skills, so I regained my mind and made a script to operate and log in Python.
Python struggled because I couldn't find a document as polite as Node.js, but here and here I decrypted the code of tplink-lb130-api / blob / master / lb130.py) and created a script.
Creating a TPLink operation class
Above I created the following 4 classes by referring to the code. ** TPLink_Common (): Class of common functions for plugs and light bulbs ** ** TPLink_Plug (): Plug-only function class ** (inherits TPLink_Common ()) ** TPLink_Bulb (): Light bulb-only function class ** (inheriting TPLink_Common ()) ** GetTPLinkData (): Class to get data using the above class **

How to execute TPLink operation class
The above class can be executed on Python code as below
** ・ When you want to turn on the power of the light bulb **
TPLink_Bulb(IP address of the light bulb).on()
** ・ When you want to turn off the power of the plug **
TPLink_Plug(IP address of the plug).off()
** ・ When you want to turn on the plug after 10 seconds **
TPLink_Plug(IP address of the plug).set_countdown_on(10)
** ・ When you want to increase the brightness of the light bulb to 10% **
TPLink_Bulb(IP address of the light bulb).brightness(10)
** ・ When you want to make the light bulb red (color light bulb only) **
TPLink_Bulb(IP address of the light bulb).red()
** ・ Get information such as on-off of light bulbs **
info = GetTPLinkData().get_plug_data(IP address of the plug)
- The above method converts the acquired json information to dict format and outputs it. Please refer to ① for the output light bulb information.
④ Creation of Python script for logging
Using the last method in the previous chapter, I created a script that logs information about light bulbs and plugs. The structure of the script is [here](https://qiita.com/c60evaporator/items/283d0569eba58830f86e#%E3%83%A1%E3%82%A4%E3%83%B3%E3%82%B9%E3%82 It is the same as% AF% E3% 83% AA% E3% 83% 97% E3% 83% 88% E4% BD% 9C% E6% 88% 90), so please read the link.
setting file
[Here](https://qiita.com/c60evaporator/items/283d0569eba58830f86e#%E8%A8%AD%E5%AE%9A%E3%83%95%E3%82%A1%E3%82%A4%E3 Like the article of% 83% AB), we created the following two types of configuration files to make it easier to manage. -DeviceList.csv: Describe the necessary information for each sensor
DeviceList.csv
ApplianceName,ApplianceType,IP,Retry
TPLink_KL130_ColorBulb_1,TPLink_ColorBulb,192.168.0.103,2
TPLink_KL110_WhiteBulb_1,TPLink_WhiteBulb,192.168.0.102,2
TPLink_HS105_Plug_1,TPLink_Plug,192.168.0.101,2
The meaning of the columns is as follows ApplianceName: Manages device names and identifies multiple devices of the same type ApplianceType: Device type. TPLink_ColorBulb: Color bulb (KL130, etc.) TPLink_WhiteBulb: White light bulb (KL110, etc.) TPLink_Plug: Smart plug (HS105, etc.) IP: IP address of the device Retry: Maximum number of re-executions Details (Re-execution count when acquisition fails, click here](https://qiita.com/c60evaporator/items/283d0569eba58830f86e#%E4%B8%8D%E5%85%B7%E5 % 90% 881peripheral% E3% 81% AE% E5% 88% 9D% E6% 9C% 9F% E5% 8C% 96% E6% 99% 82% E3% 81% AB% E3% 82% A8% E3% 83 % A9% E3% 83% BC% E3% 81% 8C% E5% 87% BA% E3% 82% 8B))
-Config.ini: Specify CSV and log output directory
config.ini [Path] CSVOutput = /share/Data/Appliance LogOutput = /share/Log/Appliance If you output both in the shared folder created by samba, you can access it from outside the Raspberry Pi, which is convenient.

If you execute the above, the acquired data will be CSV output with the device name and date and time name to the folder specified in the setting file "CSVOutput".
This completes the information acquisition.
in conclusion
It runs 24 hours a day on RaspberrypPi, and Python has more freedom than IFTTT, so you can embody various ideas. ・ Combine with a motion sensor to turn on electricity when a person enters ・ Turn off the lights if there are no people for 30 minutes or more. ・ Automatically switches the brightness of the light bulb depending on the person And so on.
I have some things I want to make, so I will write an article again when the production is completed.
