I see a useful feature for Sonoff switches to save energy by programming them turn on a coffee machine, cooker, heater, etc. a certain time every day and just turning on and off every so many minutes to maintain the heat. It would also be useful to have an ending time so that you can limit the operation a certain time of day say in the morning.
A good illustration of this is my coffee machine. You see, right now, I can program it to turn on at 7 am then turn off at 9 am every day or certain days. But leaving it on for two hours consumes a lot of energy and also overcooks the coffee. I can do this partially by using the current loop timer but I have to set and turn it off every day. It would be nice if this can be fully automated. I see many uses for this for many cookers and other applications
Can we have this features added?
