Petkit K3 Odor Spray
BLE Device — Read-only
The K3 communicates via Bluetooth Low Energy (BLE). It is read-only — Localkit receives state from the device but cannot send commands to it directly. The K3 can only be linked to a Pura Max. It is triggered by the linked Pura Max after each cleaning cycle, or manually via the Pura Max buttons.
The Petkit K3 is a Bluetooth odor spray device designed to work alongside the Pura Max litter box. It releases a deodorizing mist after each cleaning cycle. Localkit exposes its consumable levels and battery as Home Assistant sensors.
Pairing with the Pura Max
The K3 must be linked to a Pura Max in Localkit. Once linked:
- The Pura Max automatically triggers the K3 after each cleaning cycle.
- The Lightning Start and Lightning Stop buttons on the Pura Max control the K3 manually.
- The Link With sensor on the K3 shows which Pura Max it is paired with.
To pair or unpair, use the Link with K3 / Unlink from K3 actions on the Pura Max device page in Localkit.
