Email Notifications from the Portal

Notifications are supposed to work in the following way:

What types of Notifications?

• Luminaire Fault
• Duplicate Mapping
• Emergency Lighting Test Failure

We send a notification when any of those change, i.e. even if a node reported a fault and now no longer reports that fault, there will be a notification.

How often/what latency?

• The first message should be received ~20s after an issue has occurred
• Disconnections take a while to be detected (a node is said to be disconnected if we haven't received any data from it for an hour)
• After that we back off as follows (so we don't spam users):
  • 2 minutes, 30 minutes, 2 hours
  • i.e. if we have already sent an email about a luminaire fault, we won't send an email about another luminaire fault for the next 2m, then for 30m etc.
  • Unless the severity changes
