How does the Hub operate without the Internet connection (without communication with the server)?

When the Hub communication with the server fails (the Ajax logo lights red), the security system continues autonomous operation responding to all events, executing the enabled scripts, and activating the siren when applicable.

The events during the communication failure are recorded in the Hub buffer and are delivered to the Ajax applications when communication with the server is restored.

👆🏻 The Hub buffer can store up to 130 events.  

Since the Ajax applications communicate with the Hub via the server, you cannot operate the Hub via applications in the case of Internet connection failure.
If the Hub connection to the GSM network is active, it continues calling and sending SMS to users — if these notification methods are enabled.
