Looking for some neat ideas/quality of life improvements aka lifehacks I guess
Provided you live in a country that cares about transparency.
My meter has a single LED and a propietary optical connection that claims to alarm the supplier if used.
You can always wire up an ESP32 with an optical sensor that tracks the blinking of the LED. The meter should state how much energy is represented by a blink.
Example projectYep, I’ve got one of those going already! I’m currently working on improving the power consumption so I can run it off a LiFePO4 without recharging every week.
That sucks. Back here, the company that maintains the electrical grid actively stimulates the people to use such sensors. All in the name of saving energy. There’s even a page with vendors on their website.
