I recently purchased a groove box so that I could easily create displays for building infrastructure (pumps, cooling, etc.), but I have discovered there is nothing in there for alarming, alerting, logging, or events.
Groov badly needs the following:
Event trigger gadget to trigger events based on rules (comparison of device values to fixed values or limits or other device values)
Alarm gadget that responds to events with visible alarms
Alert gadget that responds to events with email alerting
Event responder gadget that changes device values in response to an event
Log viewer gadget
