I've got a similar problem with the email function.
I had to setup a local smtp relay on my lan, without TLS auth. Which forwards to gmail / outlook etc.
However, the box only ever sends test message.
Both manually triggered emails via the grand master setup or the periodic test messages setup via the installer get sent.
But it never sends any arm / disarm, alarm etc messages.
All messages types are enabled in the setup for the FM1 / FM2
and both get the the periodic test message.
Logs on the smtp relay only show attempts to send test messages.
I've left the alarm panel in alarmed state for a while and nothing happend.
Cloud works ok,
Any ideas?
