Getting Started

Follow these steps in order. The whole process takes 30–60 minutes for a typical installation.

Steps at a glance

  1. Buy the hardware — Raspberry Pi 4, ZigBee dongle, sensors, UPS
  2. Flash the SD card — stock Raspberry Pi OS Lite
  3. First boot & network — connect to your site's network
  4. Link your hub — connect the Pi to your ChillCheck account
  5. Add sensors — pair each SNZB-02LD via the local UI
  6. Assign sensors to cabinets — map sensors to fridges/freezers in the dashboard
  7. Set thresholds & contacts — define who gets alerted and when

Before you begin

You'll need:

  • A ChillCheck account — sign up at chillcheck.online if you don't have one
  • A laptop or phone on the same network as the Pi (for initial setup)
  • About 30–60 minutes

Ethernet is strongly recommended

Connect the Pi to your router via an ethernet cable if at all possible. It is more reliable than Wi-Fi and avoids most common connectivity problems. Wi-Fi can be configured later as a backup.
