Grolia
Firmware, the touchscreen interface and the grolia.com.au platform for Flush, a benchtop cabinet that grows gourmet mushrooms.
Firmware, device screens and the dashboards behind them
We write the software inside connected products and the software around them: firmware for the microcontroller, the touchscreen on the device, signed over-the-air updates, and the web platform where customers buy, pair and monitor it.
Case studies
Related work
Wastewater controller
ESP32 firmware for an automated sewage treatment system, and a browser simulator that runs the real controller code.
What we build
Firmware & connected devices
Control firmware
Sensors, outputs and control loops in C++, with safe start-up and fault handling.
Device interfaces
Touchscreen interfaces for small displays, with presets, settings and pairing.
Over-the-air updates
Signed releases that install in the background and roll back if something fails.
Simulators
Firmware logic compiled to WebAssembly so it can be tested in a browser before hardware exists.
Device APIs
Pairing, device sign-in and sensor readings stored and charted in the cloud.
Customer dashboards
A web dashboard where owners see their device, and staff see the fleet.
Approach
How we build it
We keep control logic separate from hardware drivers, so it can be tested on a laptop and in a simulator long before it runs on the board.
Steve wrote the firmware that ships in Grolia’s Flush cabinets, on Raspberry Pi RP2350 boards, and we have written control firmware for ESP32 for Sterling Civil. Both are C++ with PlatformIO. We work alongside whoever designs your circuit board and enclosure.
Questions
Common questions
Which microcontrollers do you work with?
Raspberry Pi RP2350 boards for Grolia’s Flush cabinet, and ESP32 for a wastewater controller. Both use C++ with the Arduino framework and PlatformIO.
Do you design the circuit board?
We write the software. On Grolia, the cabinet and its electronics were designed by Grolia’s own engineers, and Steve worked alongside them.
Can you test firmware before the hardware is ready?
Yes. For the wastewater controller we compiled the control code to WebAssembly so the client could run it in a browser simulator before any panel was wired.
