I’ve been using Frigate for years. The built in object detection (without subscription) is excellent and very near 100% accurate. Initial setup was somewhat of challenge though. It’s free (donations encouraged) or a low cost subscription for more advanced detection.
As interesting as this is, users are still subject to the whims of a corporation that can completely change their policies each time a new executive is hired.
There’s a graveyard somewhere for apps and services that were free or low cost (and without ads) until the company decided to change their model to restrict or eliminate free usage. Teamviewer, Dropbox, RealVNC, Google Drive, Amazon Prime (ad free) Videos, Duolingo, Youtube, Zoom and Evernote are examples that lots of individuals use.
I’ve personally been bitten by this often enough to avoid any corporation’s “free” service whenever possible.
If you’re not dealing with CGNAT, Dynamic DNS (DDNS) is relatively easy to set up, doesn’t require a VPS and is designed specifically for dealing with changing IP address endpoints.
Instead of connecting using your (sometimes changing) IP address, you use a URL that dynamically updates when your IP changes. For instance, with DDNS you would access your home network using mynetwork.ddnsservice.com. The DDNS service returns your current IP and your connection can complete. Most routers have built DDNS clients that update the DDNS service when your home IP changes.
There are various DDNS services out there, but I like DuckDNS. It’s free (or you can choose to donate), easy to set up and has worked flawlessly for me for years.
I’ve had occasional problems with z-wave devices that stop responding. The fix has required power cycling them at the breaker box, then re-interviewing and rebuilding routes. Hope that works in your case.
Have you tried re-interviewing the devices as a first step?
Battery charge limit will allow you to set it to stop charging at partial charge. Doing so greatly increases the battery lifespan and can reduce possible fire risk even further while still leaving far more backup time than a UPS would provide.
See if that laptop model allows you to limit the battery charge. If the battery’s still holding a charge, isn’t swollen, and is kept at room temperature you have about a 1 in a million chance of a battery fire.
Parking your car in your garage has hundreds of times more fire risk.
You didn’t mention it can also recognize and identify wildlife, trash cans, lawnmowers, license plates, delivery truck companies, and even faces.
