Note

Other Omron BLE devices might work by selecting a similar model during setup, but have not been formally tested. If your device does not work, please share Home Assistant debug logs and, if possible, a Bluetooth stack log from your phone.

Requirements

Home Assistant 2025.12.0 or newer (see hacs.json) and a Bluetooth adapter or ESPHome Bluetooth proxy (a Bluetooth proxy is strongly recommended for connection stability and range).

Installation

1. HACS: With HACS installed, open HACS, search for Omron, open the integration, and download it. This integration is included in the default HACS repository list, so no custom repository is needed. Manual: Alternatively, copy the custom_components/omron directory into your Home Assistant custom_components folder.
2. Restart Home Assistant.

Pairing & Configuration

Device setup and pairing are done entirely through the Home Assistant UI.

1. Enter Pairing Mode:
   • On your Omron blood pressure monitor, press and hold the Bluetooth button (or the respective connection button depending on your model) for 3-5 seconds.
   • The display should show a blinking -P- symbol. This means the device is ready to pair.
2. Add Integration:
   • In Home Assistant, go to Settings > Devices & Services.
   • Home Assistant should automatically discover the "Omron" device via Bluetooth. Click Configure.
   • If it wasn't auto-discovered, click Add Integration and search for "Omron".
3. Select Your Model:
   • Select your exact Omron model from the dropdown list.
4. Finalize Pairing:
   • Make sure -P- is still blinking on the monitor.
   • Click Submit in Home Assistant.
   • HA will securely perform the pairing sequence (programming its pairing key or performing OS-level bonding).
   • The monitor screen will display an [OK] symbol when successful.

Quick Start

Recommended ESPHome Bluetooth proxy configuration (keep the default scan interval):

esp32_ble_tracker:
  scan_parameters:
    active: true

bluetooth_proxy:
  active: true

Important Limitations

• One paired host at a time: Omron blood pressure monitors only support one paired device at a time. If you have already paired your monitor with the official Omron Connect smartphone app, you must unpair/forget the device from your phone's Bluetooth settings before connecting it to Home Assistant. Using both simultaneously is not supported by the hardware.
• Bluetooth proxy requirements: bluetooth_proxy must always have active: true, and scan_parameters should remain at default intervals. For hardware recommendations, see Great ESP32 Board for an ESPHome Bluetooth Proxy. Proxy setup, recommended devices and the connection-problem checklist: Bluetooth proxy setup. Model-specific wake/pairing conditions, error-by-error fixes, and diagnostics (Last Failure, Duration) are in Troubleshooting.
• Unverified models: Models not marked in the Supported Models table are unverified.
