Since months, I had a notification on HA saying that I have to remove the code in cong.YAML about my 4G router because there is an integration (already installed) for Huawei.
I did it.
Since, some of my automations don't work and can't send notification by SMS throug my 4G router.
When I edit my automation, I don't find any kind of notif like before.
Sorry. Actually it's working.
The alert came because the Huawei integration was not working since 2 days (I just saw it), the same day I removed the code from conf.yaml.
The huawei integration was not working because I disabled the DHCP of the 4G router. I opened a topic 2 years ago about it (still no explcation):
