If not, feel free to contact me for more information. I literally gave it away to the general public as is right. I was working on my PhD at the time and was hired by Honeywell to implement my design. all are based on this simple technology.Īm I rich? Not even close.

Store and forward, offline browsing, push technology, etc. There were many processes built off of this simple idea (it was pretty cutting edge when I first designed it).

Here, you will see the MAC address of such device, then: Use show mac address-table address , where the is the one we found in the previous step. Use show ip arp include, where is the IP of your target device.

It's a VERY simple process that I developed back in 1992 when the Interwebs were still pretty new to most people. Connect to the device that acts as default router for the target network and ping your target IP. The server puts any needed data in an xml (readable) and the thermostat (or quite a few other devices) hits that URL a few seconds later (the device told the server where it would pick up that info).Īll your device needs is a simple read-only connection to the outside world. If it needs to make a request then it gives the server a unique key. What happens is the unit makes a report to the server. As long as the unit has permission to make an outbound connection it will work. The unit is allowed access to the Internet via your setup and the router.

I can tell you exactly how I designed it. I'm the lead designer and project manager on the Honeywell systems.
