fwd03, Thanks for the response, a little delay on my part due to lack pf power in NJ. Do you have a link to that document? I only see WebControl PLC FW 3.1.6 in the Documentation section. I'm using a TEMP08 (Motorola micro controller) master into interface to the 1-Wire network.

<<DS2450 is very sensitive to noise. Make sure use a lot of capacitors to filter the power and input lines.>> I now understand your comment. I assumed you were referring to noise in the ADC results, I now see you were referring to the communications to the DS2450? I'm seeing errors about...

Thanks for the responses. I have successfully built and added a DS2450 circuit to my existing Midon TEMP08 1-Wire system. I currently have 4 thermistors being monitored in HomeSeer via this link. The readings are a bit coarse as the TEMP08 only operates the DS2450 in 8 bit / 5.12V mode but...

I had hoped to avoid this but I have indeed ordered the parts required to build a general purpose analog input card. The DS2450 is still available but only as an surface mount device making fabrication somewhat more difficult. It will be interesting to see how well it actually performs; the...

Is there any plan to build the HVAC or other general analog input card in the (near) future?

Do any of the currently available Hobby-Board 1-Wire cards offer analog inputs for externally connected sensors? I have seen references to an HVAC board which could be used for general purpose analog inputs but it does appear to be available anymore. TIA Mark

Excellent! Thanks very much.

Dan, Thanks for your response. The R900 unit in question is discussed here http://neptunetg.com/userfiles/file/products/R900%20RF%20MIU%20Wall%20or%20Pit/Publication_IM%20R900%2001_10.pdf. The R900 would attach to your physical water meter, e.g. a Neptune T-10, and probably be located on...

My water utility wants to replace my existing outside touch-pad water meter reader with a Neptune R900 RF Automated Meter Reader (AMR) unit. According to the Neptune documentation, it uses frequency hopping between 910 and 920 MHz to minimize interference and transmits every 14 seconds. Since...

<<has 5 connections, GND, DQ, +5, A, B; and it has a battery to power it even if +5V is missing.>> You are, of course, correct. When I said 'only two' (GND and DQ), it was in reference to the three 1WIO 1Wire module screw terminals; GND, DQ, and +12V. <<The TEMP08 has +5V on pin 2 of its RJ12...

<<Did the counter increase by 1 or many?>> The counter would typically increase by 1-3 counts when the furnace would start and stop (a frequent occurrence at the moment in NJ). The pencil sharpener I used to force the false counting would cause 2-3 counts every time the motor started/stopped...

I thought I would pass on some recent experimental information about using the dual counter +5V as the voltage source for the channel counting. I an using a TEMP08 (with 200mA power supply) on a single daisy chain 1Wire network about 100' long constructed with CAT5 cable. The network has 2...

Cross posting from HS: I found one of these A19 LED bulbs at The Home Depot in East Hanover, NJ for $18 and decided to give it a try on various Intermatic Z-Wave switches. It switches on and off satisfactorily using the HA02 appliance module. It switches on and off satisfactorily using the...

RadPa, Did you persue this project? I built the water meter circuit design by edcheung using a similar magnetic sensor; I have had mixed results so far, the circuit is generating pulses indicating flow event when there is none. Mark
