Re: Connect a Dual Counter to a WattNode

in response to Connect a Dual Counter to a WattNode, posted by Bill
Phil, to connect a WattNode to the Hobby Boards' counter module in a manner so as to use a Pull Up resistor configuration, is this the connection mechanism:
- WEL's 1-wire bus +5V to counter's +5 V
- Pull Up resistor between +5 and counter's A input
- WattNode + (plus) connection to counter's A input
- WattNode - (minus) connection to counter's GND
I'm out of town at the moment so I can't show this in picture form.
If this Pull Up configuration is correct, then the counter's on-board 1M resistor is in parallel to the WattNode's + and - inputs. I assume this is not material.
My second question is: can I get access to a +5 V regulated supply from my Rev. 3.2 WEL board, given that I have my WEL power switch set to unregulated power for my 3rd 1-wire network wire (my RH sensors require 9 - 12 V that's coming from the WEL)? And if so, from where?
I can string another wire for my 1-wire network (only implemented the 3 wires available at the time of purchasing the Rev. 3.2 board), to my counters out on the 1-wire network, but, I don't know where to obtain regulated +5 VDC from my Rev. 3.2 WEL unit.
Thank you.
Best regards,
Bill

This site is all about building a cool, energy efficient house, that makes maximum use of earth sheltered design, passive solar heating and cooling, geothermal exchange energy management, and right sizing of the house for it's designated use. The home's placement is on a south-facing hillside in Deep Creek Lake, Maryland. This site describes the design process, the technologies used and the expected results. We also have a comprehensive Links Page for anyone who is also interested in designing a similar project.
