Performance Issues

Card Loading Slowly

Symptoms: Card takes long time to load or update

Solutions:

1. Reduce entity count: Limit number of displayed entities
2. Optimize sensors: Use fewer, more efficient sensors
3. Check network: Slow internet affects loading
4. Optimize images: Use smaller, optimized background images
5. Disable animations: If card has custom animations

Background Images Causing Lag

Symptoms: Card becomes slow when background images are enabled

Solutions:

1. Optimize image size: Use smaller, compressed images
2. Reduce opacity: Lower opacity values use less resources
3. Use static images: Avoid dynamic image entities if performance is critical
4. Disable backgrounds: Use disable option if performance is more important

Frequent Updates

Symptoms: Card updates too often, causing lag

Solutions:

1. Check sensor update frequency: Reduce polling frequency
2. Use template sensors: Aggregate data before display
3. Limit real-time sensors: Use static data where possible

Memory Issues

Symptoms: Browser becomes slow or crashes

Solutions:

1. Reduce card count: Limit number of room cards
2. Simplify configuration: Remove unnecessary features
3. Update browser: Use latest browser version
4. Close other tabs: Free up browser memory
