Recommendations for Room Temperature Sensors

[Bill Brandt]

Sorry to jump in on the tail end of this discussion but I just got my  
internet back today.

I love my one wire set up.

I have 23 sensors monitoring temp and humidity through out the house.

I use the LinkTH by ibuttonlink.com.  It does all the temp conversion  
for you I just send a "D" command via serial bridge (PortTerm will  
work as well) and get back something like this
2888DAC800000093 00,22.00,71.53
281860C8000000D0 00,22.06,71.65
28FC6DC8000000C9 00,20.56,68.93
286A5EC800000000 00,21.37,70.40
283155C8000000A6 00,27.87,82.09
28C93BC8000000C6 00,37.43,99.28
28554BC800000067 00,25.00,76.93
280D31C40000002A 00,25.25,77.37
28AD78C80000007E 00,22.62,72.65
288B68C800000006 00,22.81,73.00
28AB32C800000098 00,19.93,67.81
286F60C4000000DF 00,20.12,68.15
260EBB8000000094 19,20.62,69.06,32
26FB8F8000000096 19,23.71,74.62,29
EOD

this is sensor ID   type,Cº,Fº,% humidity

I just parse this in Xtension with this

	if item 1 of theItems is "26FB8F8000000096 19" then <--- Maps Sensor
		dim "Temp - Living Room" to (item 3 of theItems as string) - 1  <--- 
reads temp
		dim "Humidity - Living Room" to (item 4 of theItems as string) - 1   
<---- reads humidity
		get highlow(item 3 of theItems, "Temp - Living Room") <--- sets the  
high and low for each sensor
	end if

It is very quick

I had a simliar set up to Bob Ober using the HA7E but this is much  
easier. In fact I have a Link45 if anyone wants to buy it, it's the  
same as a HA7E. After switching to the LinkTH I don't need it.  I  
also bought my sensors from ibutton.com as they offer a sensor  
mounted on a small board with RJ45 connectors and the ability to do  
the 5V power (Thought I might need it given my run length). They  
offer one in a box and one without. I mounted the ones without to a  
standard blank off plate that I drilled a hole the size of the sensor  
in and then hot glued the board to the plate. Makes for a nice neat  
clean install. I do have the advantage that I had the whole house  
wired for this so it was basically plug and play. At this point I  
can't say enough good things about the ibutton.com stuff. After  
struggling through my first go at this the most laborious task has  
been mapping the sensor id's

Now if only my CM11 hadn't become a space heater I could actually  
control my heating system.
