I have not looked at them yet but I have a number of years in IT. Pretty sure at a minimum you would need a router accessible for your Wi-Fi to be able to connect to. Normally you would not need an Internet connection but rather an Intranet which is just a fancy way of saying your internal network. The only viable reason I could see that they would need to be connected to the Internet is for updates. My grow light is Wi-fi connected and if my Internet is down my light still works.
Yeah, I understand the inter/intra part...I was the first guy to bring the internet into our county back "in the day"...bbs, dial-up modems, even had a "Planet-Connect" connection via satellite dish for downloading mail and new files. Out-going mail relays were handled by the modems calling out to a server. That was in '93-'96. I finally got "bought out" by our local cable company when they started offering Internet...the lady was a friend of mine and I saw that my little board was a dying thing so I took the offer of "free internet" from her.<grin> Anyhow, those were DOS batch file days when you ran from the command line. Once things moved to Windoze I just fell in line and became a sheep following "DOS-Killer" Bill Gates offerings.
Oh, and the computer...a 386dx20 running 2/TWO MEGS of ram (I upgraded<grin>), it had a 65Mb (yeah, megabytes!) RLL (run length limited) hard drive, and both a 5.25" and a 3.5" floppy/diskette drive...high-tech!!!! Oh, and the monitor...a .31 dot pitch CRT!!! Oh, and no mouse...didn't need one. All of that for a little over two grand!!!! My how times have changed....
So much for a jog down memory lane!
Anyhow, the plugs would have to have a micro-computer of some kind and be able to retain data (date, time, latitude) for them to work without an internet connection, wouldn't they? What I'm looking for is more than simple "on and off"...astronomical timers will follow the actual sunrise and sunset times.
I think I need more than smart plugs/timers for remote use. They make stand-alone switches that you set the latitude, date, and time on and they adjust automatically. These are usually intended to be mounted in switch/utility boxes into the wall. I was hoping some of these smart switches my have that same capability. Probably what I will do is buy one of the utility-box types of astro-switches, take a short, heavy extension cord cut in half, and attach the cut ends to the switch that is inserted in a freestanding box. It'll be portable and I can plug it into a nearby wall receptacle.
