  • See Managed to extract Hub live log for my usage via python script
  • amazing what you can do with scrapers :-) I bet I can reuse this code when scraping instagram, flickr and other places where the API is going to stop functioning.
  • I only copy and pasted the code below because I don't trust S*msung to keep the Smart Things website up.

Code by Philippe_Portes:

import platform
from bs4 import BeautifulSoup
from selenium import webdriver

import difflib

login_l = 'yourSTusername'
password_l='yourSTpassword'

#function to extract needed string

if platform.system() == 'Windows':

# Initialize difflib for later usage
d= difflib.Differ()

# here we'll use pseudo browser PhantomJS,
# but browser can be replaced with browser = webdriver.FireFox(),
# which is good for debugging.
browser = webdriver.PhantomJS(PHANTOMJS_PATH)
browser.get('https://graph-na02-useast1.api.smartthings.com/login/auth')

# We'll put the device names and the corresponding href used by ST logs to put the name in clear in the logs we export

logfile.close
Example of logs as csv file I got:
"Log_Class";"Device_Name";"Local_Log_Time";"Log_Message"
"log debug";"Arrival Sensor guest";"3:55:14 PM PST";"Creating battery event for voltage=2.2V: Arrival Sensor guest battery is 70%"
