A2/A3 Anova Precision® Cooker

The A2/A3 Anova Precision® Cooker series represents Anova's Original Precision Cooker line, featuring Bluetooth Low Energy (BLE) connectivity for remote control and monitoring. This documentation covers both available models:

  • 800W (BT-only) Model - Basic Bluetooth connectivity
  • 900W (Wi-Fi-enabled) Model - Enhanced features with Wi-Fi capability

Key Features​

  • BLE Connectivity: Control your cooker remotely using Bluetooth Low Energy
  • Interactive Control: Send commands and receive real-time responses
  • Multi-Model Support: Compatible with both 800W and 900W variants
  • Real-time Monitoring: Get instant feedback on temperature and cooking status
  • Timer Management: Set and control cooking timers remotely
  • Model-specific Features: Additional capabilities for Wi-Fi-enabled models

BLE Communication​

The Anova Precision Cooker exposes a single Bluetooth Low Energy service with a single characteristic that handles both command transmission (TX) and response reception (RX):

  • TX: Commands are sent as ASCII strings with a carriage return (\r) appended
  • RX: Responses are received as notifications, potentially in multiple chunks

Model Identification​

The device model (800W or 900W) is automatically determined when connecting by sending a "get id card" command. If the response begins with "anova f56-", the cooker is a Wi-Fi-enabled model.

Feature Availability

Some commands, such as clearing alarms and retrieving firmware versions, are exclusively available on the 900W (Wi-Fi) model. Check the Commands section for model-specific feature details.

Implementation

For complete implementation details, check the BLE Protocol and API Reference sections that demonstrate how to interact with the device using any programming language that supports BLE operations.
