This is the situation I have - Remote Home Automation without Internet.
Some of the web links might need to be copy and paste.
I have a remote location thousands miles away and visit only couple times per year.
It got break in couple time last couple years. People always suggest me to sell it and
save the trouble, but it has sentimental value more than $$$ value.
I installed couple motion detect flood lights and two 24hr lights and two timer
controlled lights. The location is subject to frequent power outbreak and Hurricane
like wind and downfall. The flood light is solid, but 24hr lights and timer lights are
no good.
So I am thinking three solutions.
Solution one uses two phone lines in the remote location.
Possible Equipments:
2 POTS(plain old telephone system/service)(actually one needs 4 pots or 3 pots + voip)
2 pots in remote location, 1 pots in local to receive call and 1 pots/voip to
call remote x10.

http://www.x10.com/automation/x10_am486.htm$20.00? home made barking dog
$???.?? power outlet
Total cost about $250 to $350 Plus cost of 4 phone lines
One for me to dial in to control x10 controllers
One for motion detect auto dialer with monitoring system(MDADM) to dial out to me.
First with dial in x10 controller, I can turn on lights with PC locally automatically
or with a cell/pots manually. So I can remove timers in remote location kill the worry
of power brownout(timer will out of sync). To solve the burn out lights problem, I
probably just need to install more x10 controlled lights. So some of them can last
long enough until my next visit.
So when MDADM dial my local number
I pick it up and monitoring it
At the same time I dial out to x10 controllers and turn on lights and barking dogs and
TV or radio...

Solution two uses one phone lines in the remote location.
Possible Equipments:
1 POTS(plain old telephone system/service)
$68.99

http://www.kvms.com/Product/MP-8.aspx$50.00?? eight 25f to 100f power extension cable
Total cost about $520 Plus cost of 2 phone lines
This solution seems promising and professional grade(at least in DTMF part), but very
expensive.
Solution three uses two phone lines in the remote location.
Possible Equipments:
2 POTS(plain old telephone system/service)(actually one needs 4 pots or 3 pots + voip)
2 pots in remote location, 1 pots in local to receive call and 1 pots/voip to
call remote controller.

$???.?? very old external modem
$50.00?? eight 25f to 100f power extension cable
Total cost about $200.00 Plus cost of 4 phone lines
This solution is cheap, but one needs 4 POTS to make it work.
In remote location, WTI RPB+ controls eight power devices.
WTI RPB+ needs a rs232 cable to be connected to a external modem which is connected to
a POTS.
Locally, one uses a PC's modem dial remote location's WTI RPB+ and control one's
remote lights and barking dog...
In solution one, only audio/noise/voice... can be heard(confirmed).
In solution two, all commands and audio can be confirmed and required only one phone
line. So I can monitor the remote location and react right away(issue DTMF commands).
Solution three is similar to solution one, but WTI RPB+ will give you confirmation and
is cheaper than x10.
Why not Internet?
POTS in the most place is still much reliable than Internet. Internet access is not
readily available in every places and in any time, but a pots/cell phone is almost
available in most location and most time frame.
I am interested in putting some automation in a vacation home where I do not maintain an internet connection. I wouldn't mind putting in a local PC running a wireless LAN for controlling the devices. Ideally my goal would be to dial into the local PC remotely via telephone line modem and remote control the unit with something like PC Anywhere.
One of the main functions I am interested in is monitoring the temperature and controlling the 240v electric baseboard heaters to turn them on before going to the house. It would be a bonus for me if the software on the local PC could monitor various conditions such as temp, flooding, glass breaking and use the modem to dial out and provide an alert.
Any ideas on what products or methods I could use would be appreciated.
