Re: Z-Wave Pool Thermostat with Water Temperature Sensor

Hi Richard,

You can use an Oregon Scientific water temp sensor THWR288.
The Homeseer xAP plug-in supports this type of sensor already and the
ACRF2 plug-in will support it in the near future.
To receive the Oregon sensors you need an RFXCOM 433.92MHz receiver.

RFXCOM has USB connected receivers and using the newest Ethernet
connected receivers you can put your Home Automation receivers and
transmitter now on the optimum location for receiving all sensors in
your property. No longer problems with RF noise radiated by the PC.
Simply put the receiver at a larger distance from the PC with a LAN or
WLAN connection and it makes the receiver now more sensitive.

If the Ethernet interface is connected to the Internet it enables you
to add remote locations to your Home Automation system. Connect your
holiday home to receive the security sensors, temperature and humidity
and switch X10 or control Harrison curtains or even control and check
the home of your grandmother.

All existing Home Automation software that runs on a Windows platform
and has interfacing software for the W800RF receiver or the RFXCOM
receiver can use the RFXCOM Ethernet interface without any
modification in the HA software thanks to the CPR (COM Port
Redirector) software.  This CPR software emulates a standard COM port
in Windows.

On other platforms like Mac and Linux, the communication protocol is
via TCP/IP with the receivers and transmitter. Of course, TCP/IP
communication is also possible on the Windows platforms.

All RFXCOM receivers have a W800RF compatible receiving mode and the
RFXCOM receiver translates all received non-X10 RF packets (like
Visonic, SecureLinc, KlikOn-KlikOff, Domia Lite) to an equivalent X10
packet. This makes it possible to process those non-X10 sensors and
remotes by all X10 oriented Home Automation software without any
modification in this Home Automation software.


There are 4 different types of RFXCOM Ethernet interfaces.
1. LAN with 1 COM port and connections for 1 or 2 receivers OR 1
transmitter,
2. WLAN with 2 COM ports and connections for 1 or 2 receivers AND 1
transmitter,
3. LAN with 2 COM ports and connections for 1 or 2 receivers AND 1
transmitter,
4. WLAN+LAN with 2 COM ports and connections for 1 or 2 receivers AND
1 transmitter.
