Groundlume SENSELaunching on Kickstarter · Waitlist gets 30% off the first 200 units
The first smart checker for your grounding products

Your grounding mat can't tell you if it's working. Until now.

Sense sits between your mat and the wall and shows a simple green light when you're truly grounded.

MEET SENSE

A small device that never stops checking.

The Sense app

Watch the charge leave your body.

While you're grounded, Sense shows the gentle flow of charge from your body into the earth, live. Calm, quiet, and strangely satisfying to watch.

The Discharging view, recreated here. In the app, the dots fall at the speed of your actual measured flow.

See it for yourself

Same person. Same minute. Three mats that look identical.

A working mat pulls your body's voltage down to earth. Sense turns that into one simple score. The difference between a healthy mat and a dying one is night and day.

NO PATH

Your body can't feel the difference between these three. That's the entire problem.

Why mats die silently

Three things kill grounding products, and none of them leave a mark.

Fabric softener

One wash with softener coats the silver threads in wax. The mat looks new. The connection is dead.

Sense catches this as a falling health score.

Cords, snaps, corrosion

Bent pins, corroded snaps, a pet chew you never noticed. The connection weakens over months, not overnight.

Sense catches this on every session.

The outlet itself

Some homes have outlets with no working ground. Your mat's plug fits fine either way, and there is nothing to feel.

Sense verifies the outlet's earth before trusting it.
For the multimeter crowd

Been testing with a multimeter? Same drop. Both hands free.

If you've done the body-voltage test, you already trust the method. Sense reads the same drop on contact, and there the two instruments agree. Then it does what your meter can't: logs all night, tracks weeks, grades the mat against its own best, and separates a mat problem from an outlet problem. Your multimeter gets one number. Sense gets the story.

Straight answers

Questions grounding people actually ask

Does it work with my existing mat, sheet, or band?

Yes. Sense sits in line between any standard grounding product and the wall, every major brand and the no-name ones too.

Does putting a device in the path weaken my grounding?

No. Sense uses the same built-in safety part that's already in every grounding cord you own, so your grounding works exactly the same. If you have a multimeter, you can check for yourself, and we'll show you how.

Does it need WiFi? Where does my data live?

Sense works on its own with any phone. WiFi adds remote access, household sharing, and automatic updates. Your measurements stay on the device and your own dashboard.

Is this a medical device?

No. Sense is a measurement instrument, like a thermometer for your grounding setup. It makes no health claims and doesn't need to. It answers one question: is yours working?

When can I get one?
