Companion devices and kit pieces for ThermalTrace. Temperature probes stay on the freeze-kit path — these prove presence, show moods, POST contacts, or finish a garage install.

Accessories FAQ
How accessories relate to probes, Bay Buddy, and the claim puck.
Do accessories replace a freeze probe?
No. Accessories are companions (mood lights, claim presence) or contact sensors (door, leak, power) and kit pieces (labels, mounts, cases). Temperature still needs a DS18B20 path such as the ESP32 freeze kit.
Which accessory should I buy first?
After a working freeze probe: claim puck + Bay Buddy for desk moods, or leak puck under a water heater. Kit labels and the probe mount kit help any install.
