When this happens, can you ping something on the internet from LAN using ip address and not a dns name ?If it works, it could be an issue on the dns side (not reachable or not answering)
If you already have a domain name and don't want to switch to something else, know that some DNS registrar have an API to handle the domains.
For a short period of time I had to rely on this and had a little python script to get my current IP and apply it to every A record in my DNS zone.It worked well (but then I took an arrow in the knee had static IP)
I have Frigate with a TPU, that is connected to Home Assistant.As soon as we leave the house (and HA detects us outside of "home") it enables recording and motion detection on Frigate.A blueprint for frigate allows to send notification on motion detection.
It's a simple but frustrating setup to put in place (thanks to Coral USB TPU lacking proper docs / updates) but now it works nicely.
You don't need Frigate+ but you could do a 1-shot buy to get enhanced detection models (my cats are often detected as persons and triggers false warning, FG+ should help)
RN I blocked access to the signup location on nginx Should be ok for now, but I'll take a look at madblog
Thanks for the tip
