How set broadcast event in Lumen

First of all add in your composer.json

    "require": {
        "laravel/lumen-framework": "5.1.*",
        "predis/predis" : "^1.1@dev",
        "vlucas/phpdotenv": "~1.0",
        "illuminate/redis": "^5.1"
    },

Edit .env ad add

CACHE_DRIVER=redis
SESSION_DRIVER=file
QUEUE_DRIVER=redis
BROADCAST_DRIVER=redis

Run composer update

In app.php comment out:

Dotenv::load(__DIR__.'/../');
$app->withFacades();
$app->withEloquent();
 $app->register(App\Providers\AppServiceProvider::class);
 $app->register(App\Providers\EventServiceProvider::class);

Try php artisan cache:clear in order to check Redis

For me this works!
