It's a VERY simple process that I developed back in 1992 when the Interwebs were still pretty new to most people. 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. Tips: You can usually get all the info you need with 5-10 pingsĪs the image above shows, the test was successful.I'm the lead designer and project manager on the Honeywell systems. Type “ping -c 5(IP address or host name) and press Enter. This functions similarly to the Network Utility app. When the Spotlight Search pops up, type "Terminal" and hit Enter. Hold down the Command key (⌘) and press the spacebar.Ģ. If the response looks like either of the below examples, the test failed:ġ. If the response looks like this, the test is successful. (In this example it was 10.0.0.2), and hit Enter.Įach Ping test makes four attempts, and gives back a response for each attempt. Type in the address (or IP address you wish to ping).
