After getting my hands on the Fibaro Starter Kit which includes a wall plug, I got kinda addicted to monitor my energy usage of my always-on switches like the television switch, Internet switch and computer switch.
Right now the electricity traffic in Singapore is S$0.0183/kWh till 30th June 2016
You can enter the value in Fibaro Home Center and it will give you your electricity usage and the cost breakdown by hour, day, week and month.
Next up, I will be getting the Aeon Labs Aeotec Home Energy Meter to install it at my circuit breaker so I can mesaure the whole house electricity usage!
Oh and the Smart Switch 6 does comes with one USB port at the side to allow you charge your USB device easily.
