GT06 false "powerCut" alarm

From highlighted text:

Then why do they mention alarm? Seems like the documentation has conflicting information, at the very least.

I dont know, maybe it's just for information that no alarm occured at that time, and if an alarm occurs, the device will send an alarm packet instead of a heartbeat packet.

And obviously, we cannot ignore this information from Wanway support:

Decided to add message type. Based on that, you can use computed attributes to filter the alarm:
