At long last a Smart app has approached energy usage AND cost per device, ST really need to move forward with energy management, currently ST does nothing smart or useful
The Tuya app approach uses user input to add missing details and calculates useage value and cost dependant on running time, a simple but effective approach
I have 4 wifi light bulbs, I input each bulbs wattage and an electricity unit cost the rest is calculated quite simply with usage graphs and actionable options dependant on needs
This is something that ST could easily implement for every device connected to ST
A very useful and smart option indeed and wayyy ahead of Samsung
