🔔 Don’t forget to re-enable notifications

Important Reminder: If you previously disabled the 'Arm/Disarm' Push Notification and 'Entry Notification' settings as a temporary fix, please re-enable them in the Smart Life App to restore full functionality (see instructions below).

Instructions:

Open Smart Life
Open OSI Alarm Device
Select Setting
Enable Entry Notification & Arm/Disarm push

🍏 A quick note for iPhone users

Due to iOS's strict notification rules, the alarm system will emit a milder, repeating bell sound. This sound replaces the previously harsher, repeating siren sound and will continue for a total of 30 seconds or until you swipe the notification to clear it. We understand that this repeating sound may be inconvenient for some users. If you'd prefer to avoid the recurring sound, you can disable the Arm/Disarm Push Notification setting in the Smart Life App. This is a temporary solution until Apple provides more customizable notification options in future iOS updates.
