-### Approving Sensors (Discovery Workflow)
+### Sensor Management (TUI)
 
-The service automatically discovers nearby Bluetooth sensors and stores them in a pending list. You approve which ones to monitor:
+The service automatically discovers nearby Bluetooth sensors. You can manage them using the built-in Text UI:
 
 ```bash
-# Start sensor discovery (if not already running)
-sudo systemctl start sensorpajen
-
-# Let it scan for a minute or two to discover sensors
-sleep 120
-
-# View discovered sensors and approve them
-sudo sensorpajen approve-sensors
+# Launch the management TUI
+sudo sensorpajen-tui
 ```
 
-The approval CLI will:
-1. Show newly discovered sensors with their current readings
-2. Ask you to approve, ignore, or skip each sensor
-3. Save approved sensors to `/etc/sensorpajen/sensors.json`
-4. Mark their status in `/var/lib/sensorpajen/discovered_sensors.json`
+The TUI allows you to:
+- **Discovery**: View newly discovered sensors and **Approve** (add to monitoring) or **Ignore** them.
+- **Configured**: View currently monitored sensors, **Edit** their names, or **Remove** them.
+- **Ignored**: View ignored sensors and **Unignore** them if you change your mind.
+
+**Keybindings:**
+- `a`: Approve selected sensor
+- `i`: Ignore selected sensor
+- `e`: Edit sensor name
+- `u`: Unignore sensor
+- `Delete`: Remove sensor from monitoring
+- `r`: Refresh data
+- `q`: Quit
 
 When you approve a sensor, it's added to your configuration and the service automatically starts monitoring it.
 
+### Legacy CLI Approval
+
+If you prefer the command line, you can still use:
+
+```bash
+sudo sensorpajen approve-sensors
+```
