README
README.mdModern Replacement for "GET" Smart Wireless Lighting System Controller
Project Intro
I have a aging Wireless Lighting System from a UK company called GET, from circa 2007. Its now so old in fact, that its no longer manufatured, and the company is no longer in existance. The setup includes a battery-operated controller (replacing the traditional UK light switch) and some mains supplied receivers to operate the lights. I buried the recievers behind the plasterboard in my apartment's ceiling when I installed the system. Its operated flawlessly since then, I don't think I've ever changed the batteries in the controller, which is testament to its solid design.
It is however, missing integration with home automation (I use Home Assistant & Alexa). Its now a deal breaker. I could replace them with somethine else, and repair the plaster.... ... but rather than add to the e-waste pile, I thought I'd put one of those microcontroller's I have in a box to good use.
Side Quests
Typically for me, I'm also diving into a few related technologies as part of this project:
- Zephyr: I'm curious to learn this framework.
- Home Assistant Integration: I use HA for all my other stuff so this is given.
- Thread/Matter: I have tons Zigbee devices already, and want learn more about the newer connected device protocols.
Built with Zephyr v3.6.0
Reverse Engineering the Controller
After some snooping inside the contoller it seems to be 433Mhz FSK, based on a HiMark TX4915-LF RF chip. Only datasheets HiMark TX4915 say its for ASK, but the silksreen on the transmiter clearly says 433 FSK.
My Controller Setup
From the GET Smart Wireless Lighting System Manual I'm using the controller in "Dimming Mode", with 2 lights, on buttons 1 and 2 respectively.
Sniffing the data

Questions
How big is the Get smart controller PCB?
It measures 46.2 × 44.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Get smart controller use?
22 parts, built around the ESP32-S3-WROOM-1-N8, AMS1117-3.3, MMBT3904 and SK6812. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Get smart controller KiCad files?
From the demonday/get-smart-controller repository on GitHub, at the commit this page was made from: the board is hardware/design/get-smart-controller.kicad_pcb and its schematic hardware/design/get-smart-controller.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Get smart controller design in my own project?
Its repository states no licence, so its author keeps all rights: ask demonday before reusing the design.
