ChillPoint is a rechargeable, handheld device that puts complete control of Thermochron iButtons in one pocket-sized tool you can carry anywhere it’s needed.

Simply touch an iButton to the integrated reader and you can pull a full mission’s worth of time-stamped temperature data in seconds. You can spot alarm events at a glance, and launch or halt logging missions on the spot — all from a web interface you open on any phone, tablet, or laptop. No clunky setup required. No desktop software to install. No cables.

Built For The Field

ChillPoint is designed for the places iButtons are typically deployed: receiving docks, cold storage rooms, delivery trucks, lab benches, and wherever else a shipment or sample ends up. ChillPoint creates its own Wi-Fi network in the field so you can connect directly from a phone, or joins your local network back at the office so the whole team can reach it. Retrieved logs are saved to onboard storage, so your data is captured the moment you read an iButton.

Under the hood, a dedicated hardware crypto chip provides a foundation for secure communication between the device and your browser, with keys and sensitive operations handled in silicon rather than software. And because both the hardware design and the firmware are fully open source, you can inspect the schematics, audit the code, or extend the platform to fit your own workflow — a meaningful advantage for regulated industries where validation and transparency matter, and an open invitation for makers and engineers who want to build on a proven foundation.

The simple web interface lets you surface alarms and other data at a glance. Know within moments if a shipment has been compromised, a storage environment has drifted out of spec, or an experiment has encountered an excursion — without scrolling through raw data. More than just reading log data, ChillPoint can let you start, stop, and configure missions on the spot, making your iButton deployment more flexible than ever. No matter your industry or goal—from pharmaceutical to HVAC validation, and everything in-between—ChillPoint is the ultimate tool for temperature data capture from iButton sensors.

Open Source

Both the hardware design and the firmware/software are fully open source. Inspect the schematics, audit the code, modify the web interface, or adapt the platform to your own workflow. There are no black boxes here — you get complete visibility into how your data is collected, stored, and transmitted. For regulated industries, that transparency is a pathway to easier validation and greater confidence in your tooling. For makers and engineers, it’s an invitation to build on top of a proven foundation. Schematics and software will be published before units ship.
