Some projects explain what we do better than any service page could. We've just published the full story of one of them: a small craft brewery in Croatia that went from a hand-welded rig and a thermometer to a brewhouse that runs itself and reports to a phone thirty minutes away.

The short version: the first batch was brewed manually in November 2021, with every temperature being somebody's job to watch. Four months later the rig went digital — a Raspberry Pi controlling two pumps, heating and cooling through solid-state relays, DS18B20 sensors measuring every degree, a recipe engine stepping through each mash automatically, and a mobile app with push notifications closing the loop. By late 2023 the same controller had absorbed a commercial tank and a second fermenter without breaking stride.
Seventy-three batches later, the brewer's job on brew day is pouring grain in and taking it out. The system does the rest, and tells him — wherever he is — if anything drifts.
Why we're sharing it
Two reasons. First, because this is what "business automation" actually looks like in practice: not an abstract diagram, but relays, sensors and software wrapped around a real process that used to eat someone's time. Second, because the same pattern applies far beyond beer. Greenhouses, wine cellars, server rooms, production lines — if it has temperatures, pumps or schedules, it can probably run itself and report to your phone.
If you have a process like that, tell us about it — a senior engineer will give you an honest read on whether it's worth automating. And if you're curious how the brewery approach scales up, the case study links to our commercial-scale brewery monitoring demo that this very project inspired.
