Talk to things just like you would a person

Hardware and AI that translates sensor data into conversations. Ask your crops how they're doing. Ask your warehouse if it's secure. Ask your shipments if they're on time.

We'll never share your data with anyone

Complete stack. Completely included

Global 5G with data included. No servers to manage, no databases to configure. Everything you need to go from prototype to production.

“You can do IoT from scratch. Build all kinds of custom hardware, firmware, software, hunt for connectivity and use the data in 2028 💾 or you can turn to Silicon Witchery – and deploy next week!”

– Onomondo press team

Hardware that just works

The S2 Module ships with global connectivity included and can be programmed completely remotely. Deploy sensors in the field and tweak algorithms without bringing devices back to the lab. Made a mistake? Just fix your code in the browser, and changes take effect immediately. No risk of bricking.

Silicon Witchery S2 Modules

Build applications, not tech stacks

Superstack is fleet management, remote coding, data storage and AI all in one place. Build AI workflows on real sensor data. Instead of dashboards, craft agents that serve information through interfaces people already use. Your data stays secure and is never exposed to AI providers. Hardware, connectivity, cloud, database, and AI. All included.

Frequently Asked Questions

Do I really just text it like a normal conversation?

Yes. No dashboards, no data analysis required. Send a WhatsApp message or text asking your question in plain English, and get a plain English answer back. "Are my animals okay?" "Is the warehouse secure?" "What's the temperature in zone 3?" It works exactly like texting a person who's monitoring your equipment.

How does the AI know it's giving me the right answer?

Unlike typical AI that guesses answers, ours generates algorithms, the same kind an expert data analyst would write. It then runs your sensor data through these algorithms in a secure environment to get real calculations. Your data never leaves our servers, and the AI never "hallucinates" responses. Every answer is mathematically derived from your actual sensor readings.

Is this powerful enough for serious applications?

Absolutely. The S2 module handles everything from livestock monitoring to industrial automation. It supports LTE Cat-M1 with speeds up to 1Mbps, multiple simultaneous sensor connections, and can be remotely programmed in the field. This isn't a hobby development board. It's production-grade hardware built for real businesses.

What if I'm not an IoT expert?

That's exactly who we built this for. The hardware comes pre-configured with connectivity included. Setup is entering a number and pressing a button. No infrastructure to build, no cloud services to configure, no databases to manage. If you've ever set up an iPhone, you can set up an S2.

What sensors can I connect to it?

Any sensor that provides numerical readings. Temperature, humidity, motion, GPS coordinates, soil moisture, chemical levels, light intensity, pressure, distance, and more. The AI works with data like "soil moisture = 38%" or "temperature = 22°C". The S2 provides GPIO, I2C, SPI, PWM, and analog inputs for connecting industry standard sensors and actuators.

What about connectivity and data plans?

All included. The S2 comes with a built-in SIM card and data plan. No need to source cellular connectivity separately or manage carrier relationships. It works out of the box, wherever there's cellular coverage.

What technical skills do I need?

If you've worked with Raspberry Pi or Arduino, you'll find this simpler. If you're a web developer, you'll feel right at home with our cloud-based Lua editor. No firmware experience needed. And if you are a firmware engineer, you'll have access to low-level drivers and can build custom algorithms without wrestling with RTOS APIs or embedded toolchains. It's accessible enough for beginners, powerful enough for experts.
