What is it that you don't understand? You're probably just put off by the "scary" Greek letters, if you force yourself to look at it, you'll find it's rather simple.
(ε) and (φ) are constants, and since their values are 4 and 0,25, when multiplied together they give 1. Multiply m~i~ by 1 and you simply get m~i~
I've got smart shutters that open and close automatically based on time, smart awnings which lower or raise based on the sun, to allow air flow when the shade isn't needed, smart lights that can be turned off all together with a button near my door when I leave, movement sensors in a few rooms that turn on the light but only at certain times of the day (essentially I don't want my corridor light to flash me when I go to the bathroom during the night), energy meters and smart plugs that allow me to optimize my electricity costs.
It's not for everyone but it's quite useful.
Here in Italy we have "electoral cards" which are issued once every so many years and get reissued when expired or when you move. You need that AND your ID to vote.
Nobody makes a fuss. Just have to be an adult and remember to check if you lost yours sometime before you have to vote. Seems like a good minimum requirement for voting, being able to hold on a piece of paper.
