To be cynical regarding that link, there are 2 separate facts presented but not a good explanation of why the two are related. 1) A chinese electricity company began collecting wireless sensor data in 2014 2) In April 2018 their profits were up $315M Did they begin doing more business? Did their competition remain the same? Are they subsidized by the government somehow? So many reasons why a utility company could be more profitable, they should explain the connection between the monitoring and profitability, otherwise someone can probably show you evidence that switching brands of office coffee increase profitability 200%.
