(***) In notifications

What event type?

telegram

Telegram is not an event type. It's a delivery channel.

Geofence entered , and any other .

It should work if you're using the default templates.

I tried a clean docker installation, I tried downloading templates from git and substituting them locally, still the asterisks..

You don't need to download anything.

I'll try again tomorrow. But as I said, I completely deleted the image and did a clean install, and it still doesn't work. I don't understand how to track this down; there's nothing in the logs.

I don't understand how to track this down

I tracked it down by debugging in source code. There is no other way I know of, since traccar does not produce log messages on missing templates.

Please provide the steps how you're testing if your notifications work. See also: https://github.com/traccar/traccar/issues/5702

Test button will return this and that's expected.

Hi @bravo.123

Since 6.9.0 the content of the test message is now "(***)" instead of "Test message". With the change to the notification templates, the traccar developers decided to remove the test.vm template.

I was also tricked by the same change and spent several hours of debugging until I figured out, that simply, the test message template was removed without notice.

So there is no way to check with the "TEST MESSAGE" if the templates are configured correctly, at the moment.

You need to check by having a device triggering a real alarm or creating a mock alarm.

Tell me if you need further infos.
All the best

Oh, thank you so much! It's just that after the update, I also had real alerts with asterisks. That's why I started to figure it out. Not an obvious behavior in my opinion. It would be better if real messages were sent.
