    As indicated it could be interesting but a number of these calculators use figures quite removed from the actual. Spot checks are freezers at 300kWh per year is on the low side for non energy saver types and 450kWh is closer as can be seen in our shops. Also their average for hair dryers of 1500W is lower than those bought today which I think would be more in in the 1800 to 2200W range. Also a big difference for desktops in the range of 30 to 100W.

    Keep in mind that many of these calculators are from the USA which has 110 V. You canít draw 2000W from a domestic wall socket at 110V

    This is a MAJOR problem for appliances like Coffee Machines, kettles, hair dryers, heaters, toasters etc.

    High power appliances use two phase 220V or 110V AND Gas.

    Evening all,
    I have AN ellies energy monitor and a Bneta smart wifi plug. My old desktop uses 103
    Watt.

    Consider spending a few rand te determine exact usage.

    Total spend was R1, 400, but now I know my usage.

    Of jy kan a Shelly EM koop. Hy tap in jou DB in so jy run niks via dit nie, so dit werk die power factor uit ook dan. Jy kry 2 CT clamps saam dan wat jy een oor die main in sit en die ander een wat se loads jy wil dop hou. Dit n relay ouput wat jy kan beheer dan. Wat nice is, jy kan die shelly program tussen power levels, so bv as jy die shelly stel dat hy op tel op die main CT clamp "bv 6000w" max, dan kan jy die shelly stel dat hy die 2 clamp dop hou, as daar n load is op hom en daar trek n groter load op die min clamp verby die gestelde 6000w, dan sal die relay wat jy gestel het, die load op die clamp 2 se kant af sit, tot die main load drop, dan sal hy die load op die CT clamp 2 weer aan sit. Werk goed vir n solar setup as jy groot loads op tye moet run.

    Wat ek like is, jy kan via APP in log, of deur jou rekenaar of via die IP address van die unit. Jy kan die SHELLY EM op stell dat dit as n Wife extension spot werk ook so all kou shelly stuff connect aan mekaar so.
