Perfect for the home automation geek

Great product, we have four in our control cabinet and use it to get a good understanding how much electricity we are using and where in much more detail than before. Which is nice because it help us reduce a significant amount and gave us good insights how many battery power (off grid home) we need to become fully self sufficient. + trustworthy and very detailed + doesn’t require cloud + easy to install for home assistance

Perfetto con il filtro anti Spike.

Semplicemente fantastico articolo, l'unica pecca è che bisogna stare attenti ai carichi, nel mio caso utilizzando carichi induttivi necessita del filtro che commercializza sempre shelly, altrimenti non funziona correttamente e delle volte va in crash e bisogna resettarlo
