measure the time once with a timer to check how long it usually takes for the geyser to reach the desired temp you prefer, covert min to seconds and that's your timer, old school way of doing but works.Thanks @theironhorse99 and @NT40 for the clarification.
Is there a way to link a thermostat to the smart plug so that the dumb geyser shuts off at the required temp? If yes, how to ensure that the thermostat is indeed gets the right values from the geyser?
otherwise the smart plug is just a device outside the geyser ecosystem , irrespective of the load connected to it you are just using the timer and smart features.
my geyser scenario is different , for me it was more about forgetting turning off geyser after bath hence wastage of power so i have a 25 mins times , in that 25 mins 2 people can finish the shower and even if we forget the geyser turns off, even if it takes more than 25 mins for 2/3 people to take shower the water inside has already reached the needed temperature for a family of 3 hence no need to turn on geyser again,
worst case scenario middle of bath if geyser is needed again its just an alexa call away.
