Remote Control of My Home Thermostat

Proliphix makes ethernet connectable thermostats. I've got one of their NT20E units. Works as expected. I can connect either directly to it (through the firewall at home) or through their website service. Either way works well.

The trouble with anything that connects by the phone is using the phone for anything else. You end up tying up the phone on that one task. Or you end up with a serious mess of a hack using some of the few pieces of software for consumer voice response applications. Most are a pain in the ass to set up and only work with one or two rather expensive phone interfaces. Seems like it ought to be an easy solution, it ain't.

Truth be told, once you set up a decent schedule most thermostats never need to be changed. Except for seasonal changes, of course. But for regular day to day stuff there's not much point to it. There's a high likelihood that efforts to "save money" are going to end up costing more in the long run. There are always going to be exceptions, of course, but those edge cases don't come close to justifying it for the majority of situations.

That said as someone that's squandered more than his fair share of pennies trying to automate crap.

After recieving your message, I looked around a bit. I found a system on smarthome.com that uses my home phone. It seems to be ok because its not online all the time. It only uses the phone when I "call" the system to make changes or to get a status report.

The biggest problem I haven't seen a fix for is my 5th wheel RV. When I retire in a few years, my wife & I plan on full time traveling in the RV for a number of years. Since the RV is not tied down, but frequently on the move, any system that uses a land line phone won't work. A cell phone system could be expensive because the system would require a built in phone and a contract with a local cell provider. I'm considering the internet as an option, but I haven't seen any systems that use the internet to communicate remotely.

Then you missed the earlier suggestion to look at Proliphix. That's what they do. You access them from your home network and/or from the Internet. You can access directly if you know your home IP address. If your home IP address varies, you can access them from the Proliphix web site. (In that situation, the thermostat "phones home" to Proliphix periodically to report its current IP address). I can control mine from any Internet connected computer or my iPhone.

Thanks for the help. This does solve my problem!
