I got the fine youless - electrical energy monitor device for 80€. this device is nearly 10 year on market, but unbeatable. What in the world is about the marketing of this netherlandish company - only in netherland language the homepage, not in english, neither in german. but there is a distributer in Germany (bg-etech.de) - homepage in german :)) at your current meter - if it works with the good old Ferraris principal, you have to mount it with a adhesive tape, after a while it is worn out. The position procedure ist possible with a lot corrections. So I decided to create this box, glue it with double sided tape, by using the square adjust helping part with the center hole. Use this sqarepart in the box by using the h5mm hole targeting on the middle of the LED in modern current meters or on the red circling mark on your old turning plate meter.

Don't know how much people out in the world to need this too - enjoy! perhaps you visit my youtube channel to find diy videos and perhaps you'll improve your german, like I do with english videos.

Update Oct 11.2021 I tried out for me this version filenames are ending for screw. there are 4 hooks, under this hooks you slide the also added top for screw-part. you'll need 1 M5 screw, then you slide it under the hooks and tighten gentle the screw - now your youless fits perfect.

Thanks - bye-bye from good old Germany Wolfgang Ley - Basteley
