Curious how a homemade wind turbine experiment launched a global open-source energy monitoring movement? 
In this episode of Take It EV, I sit down with Glyn from Open Energy Monitor, who turned a backyard project into a worldwide platform over a decade. From Arduino tinkering and DIY kits to sleek devices, Glyn shares how this subscription-free tool integrates with devices like Home Assistant for pure data ownership.

We dive into his heat pump monitoring passion—born from his own install—and why it beats basic apps, plus his electric camper van adventures, cooking on battery power while roaming Europe. It’s a dose of practical ingenuity and community-driven eco-innovation.
