Speed limit email notificatios

Hi everyone. I currently use traccar 4.0, how can I configure the speed limit for a vehicle and when I exceed it I receive the notification by email? I already tried several methods but I can't, I only get the geofencing notifications by email correctly. Thanks!

Please provide details on what you've tried so far.

Thanks for answering, on the main Settings / Server / Attributes page, I have added KM / h so that the speed is seen in that unit.

For the configuration that the notification arrives when a vehicle exceeds 60km / h I tried the following:

1.- Configuration / Notifications / Add (+) /
Type: Speed limit exceeded
Channels: Mail
Attributes / Add (+) /
Name: Speed max
Value: 60 or 060 (I tried both)

2.- Configuration / Computed Attributes / Add (+)
Description: Speed max
Attribute. OBD Speed
Expression: 60
Type: Number

The 2 configurations I assigned to the selected vehicle but I can't get the notification to the email.

Second part doesn't make any sense. You have to set a speed limit for devices (Device > Edit > Attributes > Add > Speed Limit).

Very good, I already made the configuration as you indicate. At the moment I cannot test since the vehicle is not in motion. Tomorrow I share the results. Thank you!!!

Ready!! everything works fine, I didn't know that the maximum speed had to be set there. Thank you!!
