〇 When using with Pokémon Sleep
<Wake-up and bedtime alarms>
・ You can disable vibration in the Pokémon GO Plus + Settings. (Please see here for more details on settings.)
Note: Even if alarms are turned on in your Pokémon Sleep app, if your Pokémon GO Plus + is in silent mode, its vibrations, lights, and sounds will be turned off, effectively disabling alarms.
〇 When using with Pokémon GO
・ While you cannot disable vibration for Pokémon and PokéStop notifications, you can disable notifications themselves. To change your settings, start Pokémon GO, tap the Poké Ball icon, and select Settings in the top right.
Note: You can’t disable the vibrations that occur at the start and end of sleep tracking.
