Thanks for reading! >Is there a way to add a software layer to your hardware idea to bring in recurring revenue? Yeah, I've thought about that a lot. The most obvious way to do it would be to add cloud access, so customers pay me $5/device/month or something, and they can access their device over the Internet through a web gateway I manage. But then that gets me into the territory of "it's A Big Deal if this goes down," so I'm not sure. I also sell a premium version of the software with some extra features. Customers get it free when they buy a device. They keep the software forever, but after 1 year, they can pay some amount every month to continue receiving updates. I'm still kind of iffy on my strategy here, though. The first renewals aren't up until January 2022, so I might do something different by then.
