SC4 Technologies LLC
We build the connected things — and help other people build theirs.
SC4 Technologies is a small development and consulting studio. We take connected products from a sketch on a napkin all the way to something running in the real world: sensors and firmware, the cloud behind them, and the app people actually open.
What we do
Two halves of the same job
Most of our work falls into one of two buckets — and the two feed each other. What we learn shipping our own products is what we bring to client work.
Product development
We build and ship our own connected products, end to end. That means picking hardware that's affordable and actually available, writing the firmware and cloud services that hold it together, and designing apps people can figure out without a manual.
Consulting
Sometimes you don't need a whole team — you need someone who has already made the mistakes. We help with architecture, technology selection, prototyping, and getting a stalled project unstuck.
Things we like working with
- LoRa & LoRaWAN
- ESP32 & embedded sensors
- Node.js
- Flutter
- Cloudflare Workers
- Off-the-shelf IoT hardware
Our flagship project
Boat & RV Guardian
A monitoring system for boats and RVs. It watches for the things that quietly ruin a season — a leak under the floor, a battery bleeding out, shore power dropping while you're three states away — and tells you before it becomes a repair bill.
Affordable hardware
Built around off-the-shelf sensors and valves you can buy today, so getting started doesn't mean a custom install and a four-figure invoice.
Free core app
The core monitoring app is free, on iOS, Android, and the web, with optional hosted plans when you want remote access, sharing, and alerts while the app is closed.
Your call on the cloud
Run it fully local with no account at all, or use the hosted cloud for remote monitoring. It's a per-device choice you make explicitly.
Support
Need a hand, or want to talk about a project?
Using one of our apps and something isn't working? Head to Guardian's support page — that's the fastest route to us. For consulting, partnerships, or anything else, email works fine.
