I'm looking for a solution (preferably a readymade device or circuit) which I can attach with the power socket of my washing machine (for example) to know how many hours it was kept running for that day or since the last time the timer was reset.. Just like one can check the miles driven in a car.
Further usability could be expected such as when the machine is switched on, it's clock resumes and keeps running until machine is switched off. The device would probably be requiring its separate power source too (or maybe some inbuilt battery) to remember the last duration from where it resumes.
If I'm at the wrong place to ask this question, please suggest and migrate it to correct place.
Thank you.
