It is time to implement vehicle notifications (charge started, charge completed, charge interrupted, etc) in the vehicle modules I am supporting. It seems that this can be done in the vehicle.{h,cpp} framework in a standard manner, and work across all vehicle types. However, I guess that will break any notifications already being produced by other vehicle types. My suggestion is: A config parameter ‘notifications’, with individual instances to turn on/off the notifications. Default is all enabled. OvmsVehicle::MetricModified picks up metric changes and issues the standard notifications (checking ‘notifications’ parameter appropriately). charge_mode=>charging: Notify charge started charge_mode=>topoff: Notify charge started charge_mode=>heating: Notify battery heating started charge_mode=>done: Notify charge completed charge_mode=>stopped: Notify charge interrupted valet_mode=>on: Notify valet mode enabled valet_mode=>off: Notify valet mode disabled alarm=>on: Notify alarm is sounding alarm=>off: Notify alarm is off All the above should be suppressed for the initial setting of each parameter. I will have to look into metrics to see how best that should be done; one neat way is to keep a modification count (rather than the current m_defined boolean). Does that make sense? Any objections/suggestions? Regards, Mark
