So far the only thing I find that I don't particularly care for is that apparently you need the reolink app to set up the cameras for the first time. I wish there was an open source way of doing it, but I can at least get their app properly through the Aurora store in order to at least configure it. And I'm guessing that I will have to enable parental controls on my router and disable the hub from being able to access the internet. They may well be telling the truth about not using my data nefariously, but if I can just stop the hub from accessing the internet entirely, except during specific times where I manually check for software updates, then they can't do anything.
Here at least, our mail is absolutely never delivered in the morning. It's always mid to late afternoon. Although perhaps a door sensor might work better anyway, because sometimes if the mail person gets here really late, it might be dark, especially during winter, with the time change.
Get yourself a solar node and a 30 foot flagpole and put it up because height is might and you would be absolutely amazed the kind of things you can find with a high node acting as a relay. We have a node where I live that is 200 feet up on a tower and during band openings I can receive nodes from over 300 miles away in a lot of cases.
