I measure it once using energy metre, bought from shopee for rm30 only

Got some tariff per watt need to be considered. End up estimating around rm260 and the bill came in around rm275, abit deviate since i only measure quite accurately power hungry appliances like air cond, refri,air fryer, microwave and cooling/heating stuff.

Abit hassle but ya i plug and measure one by one.. u take rate per hour, then measure how long use.

I plotted cumulative usage due to tariff block, higher wattage u use, higher bills since each tariff different charge.
