thank you very much Pete
Pete, the only way to set this, is for Device, it is not possible to set for Groups or Global, I would like to set to all devices, any ideas ? change source code ?
Hi mate you will need to change code as it cannot be set per group or globally. I've already checked in below thread.
Hi, can anyone tell me where in the source code do I need to make changes to create a new notification ?
I would like to create a new notification that help clients to know if the vehicle is more then x hours offline.
like: Vehicle CARXXX is more than 12 hours offline, please check it. ( I would like to send push,sms,mail to the client )
thanks
