+# useLocation() Refactoring Summary
+
+## Goal
+Remove the `useLocation()` hook from `/ui/src/routes/devices.$id.tsx` to prevent unnecessary re-renders when nested routes are rendered.
+
+## Problem
+The `useLocation()` hook was being used in two places in the main device component:
+
+1. **In the `onModalClose` callback** - checking if the current path is not "/other-session"
+2. **In the `ConnectionStatusElement` useMemo** - checking if the current path includes "other-session"
+
+When nested routes rendered, this caused the entire component to re-render due to location changes.
+
+## Solution Implemented
+
+### 1. Removed useLocation() Import and Usage
+- Removed `useLocation` from the React Router imports
+- Removed `const location = useLocation();` from the component
+
+### 2. Replaced ConnectionStatusElement Logic
+**Before:**
+- Used a `useMemo` that depended on `location.pathname`
+- This caused re-renders whenever the location changed
+
+**After:**
+- Created a `createConnectionStatusElement` helper function that accepts `pathname` as a parameter
+- Use `window.location.pathname` to get the current path without subscribing to React Router's location changes
+- This eliminates the dependency on the React Router location state
+
+### 3. Replaced onModalClose Logic
+**Before:**
+```javascript
+const onModalClose = useCallback(() => {
+ if (location.pathname !== "/other-session") navigateTo("/");
+}, [navigateTo, location.pathname]);
+```
+
+**After:**
+```javascript
+const onModalClose = useCallback(() => {
+ // Get the current pathname without useLocation
+ const currentPathname = window.location.pathname;
+ if (currentPathname !== "/other-session") navigateTo("/");
+}, [navigateTo]);
+```
+
+## Benefits
+
+1. **Prevents Unnecessary Re-renders**: The component no longer re-renders when nested routes change location
+2. **Maintains Same Functionality**: All existing behavior is preserved
+3. **Performance Improvement**: By removing the React Router location dependency, the component only re-renders when its own state or props change
+4. **Clean Implementation**: Uses native `window.location.pathname` instead of React Router's location state for simple pathname checks
+
+## Verification
+
+- TypeScript compilation passes without errors
+- Build completes successfully
+- All functionality is preserved while eliminating the re-render issue
+
+## Files Modified
+
+- `/ui/src/routes/devices.$id.tsx` - Main component refactored to remove useLocation dependency
+
+The refactoring successfully achieves the goal of preventing unnecessary re-renders while maintaining all existing functionality.
