Customize Alerts/Templates

Dear Devs, Dear Community,

is there any possibility to customize the Alert (Message)? 

ATM Ive got the following Alerts:

2020-06-19 06:23:19 +02:00
ALERT : Please check asap

Device: 192.168.44.130
Entity: Temperature

Device Uptime: 8 days, 9h 19m 36s

More information:

Which not helping much, cause I didn't know which location, is the temp under or over the threshold, what is the temperature and so on.

So how and where can I customize that alert message? Or isn't it possible at all?

Thanks a lot,

best,

meg
