Research & Development
We build the instruments the cloud left behind.
Trebuoj is a small R&D studio building hardware and running the infrastructure behind it ourselves — no subscription fees, no big-tech cloud platform, just a device that works the moment you plug it in.
No monthly fee Solar powered Works off-grid
One principle across everything we build: your data, on your network, with no monthly fee.
How it works
Whatever you're measuring, our devices follow the same three steps — no installer visit, and nothing to set up before the hardware is in your hands.
Fit it and power it
Mount it or wire it in, and switch it on. Every unit ships ready to run.
Put it on your network
Each device hosts its own setup page, so it joins your network without an app or an account.
Watch it live
Readings arrive continuously, with alerts the moment something needs attention.

What you get from us, in writing
Small studio, plainly stated terms. These are the numbers we hold ourselves to.
Why no subscription
No monthly fee
Most connected sensors charge you a subscription just to see your own readings. We run the infrastructure ourselves and don't charge for it — buy the hardware once, keep using it for as long as it lasts.
Design for the edge
Off-grid sites don't have reliable WiFi or mains power. Our firmware falls back across connectivity options and is built around solar budgets from the first line of code, not bolted on afterward.
Ship it plain
No app-store gatekeeping. Install it like any web page and keep using it for as long as the hardware lasts.
Talk to us about your site
Tank, borehole, reservoir or a solar install — tell us the setup and we'll tell you straight whether AquaSense or SolarSense fits. Enquiries about pricing, bulk orders and custom builds are welcome.
