How do we bring a hub or node online?
Use the guided flasher to load firmware, mint secrets, and set the first network credentials. Once flashed and provisioned, the hub is typically ready for validation and handoff. If a Wi-Fi hub later loses Wi-Fi, or you clear saved credentials with a long BOOT hold, it comes back with its maintenance AP so you can join Hub-<device-id> and enter new Wi-Fi details at http://192.168.4.1 without reflashing. The admin console still shows heartbeats, labels, and secret state after that recovery step.
How do I map a new node or move a sensor to another cooler?
Open /admin and click 🛠 Manage Equipment. Use Heard But Unmapped for brand-new sensors, the hub-grouped smart sections for equipment that is already mapped, and Saved But Detached for equipment records you want to reattach later. Enter or update the equipment name and type, confirm the node and hub selection, then use the single Create & map or Save button for that row. Remove from this hub only removes one hub link, Detach node keeps the equipment record but unpairs the node, and the hub-local /nodes page is the same-LAN fallback when you need local recovery.
Step-by-step mapping guide →Why LoRa instead of Wi-Fi/BLE?
LoRa handles the local sensor-to-hub link through stainless and walls where Wi-Fi and BLE often drop. The hub can then use its own upstream path, including a dedicated LTE gateway when needed, so teams are not depending only on venue Wi-Fi for either in-kitchen coverage or cloud delivery. It still supports, rather than replaces, manual monitoring procedures.
What alerts ship today?
Too-warm or too-cold equipment, additional escalated alerts for emergency fridge/freezer readings, low battery, and sensors that stop checking in can trigger push + email. Recipients come from the Alerts modal or your alert settings, and email may use your SMTP settings or a Kitchen Toolkit-managed pilot-stage outbound path depending on the feature and configuration. These are operational notifications, not a bulk marketing mailer, and alerts clear once readings recover.
Do probes need scheduled recalibration?
No. Nodes use factory-calibrated probes and are meant to be set-and-forget in normal service. Kitchen Toolkit does not put them on a calendar schedule. If a node stays more than 0.7°C away from its rolling average for about 10 minutes, Node Status will flag it for verification so you can inspect placement and run the ice-bath routine only if needed. The normal field path is the PRG/BOOT menu: quick double-tap to open it, then select Calibration.
Verification steps →How do I open the node menu or turn a node off?
Quick double-tap the node’s PRG/BOOT button to open the on-device menu. A single tap cycles through the options and holding the button selects the highlighted item. That menu now includes Calibration, Turn off, and Exit. Turn off shuts down the OLED, radio, and scheduled transmissions until you press the RST button. If you only need an immediate reading for pairing, hold PRG/BOOT for about 800 ms outside the menu instead.
