Embedded
When the device you need is not in any catalog, we build it: board, firmware and network connection. At its heart, almost always, an ESP32.
Why the ESP32
Wi-Fi and Bluetooth on board, enough power to decide on the spot without asking a server, and consumption low enough to run on batteries too.
Plus a mature ecosystem: components that are easy to source, open development tools, public documentation. A device that can still be repaired ten years from now.
What goes in the box
Custom boards
From schematic to printed circuit board, with components chosen to last inside an electrical panel or outdoors.
Firmware in C
Written on the manufacturer's official framework, readable and documented. No code that only its author knows how to restart.
Radio
Wi-Fi and Bluetooth LE as standard, LoRa for long distances at minimal power, mobile networks where nothing else reaches.
Power
Mains power or, where there is no socket, a solar panel with an MPPT charge controller and LiFePO4 batteries.
Integration
The data goes where it is needed: into the monitoring system, into Home Assistant, onto a web dashboard.
From idea to installed device
The problem
You tell us what the device must do, where it will live and who will use it.
The prototype
On the bench, with test components, until it behaves exactly as it should.
The board
Printed circuit board, final firmware, an enclosure fit for where it will go.
In the field
Installation, testing on site and maintenance over the years.

Before the ESP32
Before it came Microchip PICs, and before those a home-built Z80 with a hand-written BIOS. The part numbers change, the method does not: understand the problem, prove it on the bench, install it only when it holds.
