Im moving into a different house and considering starting over with Z-Wave and the VeraEdge seems attractive with it being able to link with so many Z-Wave venders and grab IP devices over your home network.  Can anyone share there experience with the VeraEdge?  From reviews I've seen looks like...

100% yes from me as well on the more efficient and flexible switching supply!!  I run my WC8 boards at 12V to be common with other devices and the board is hot and draws 0.210ma sitting idle. 

I hooked up a O-scope to one of the DO's and wrote a simple on-off PLC, 50ms on and 50ms off.   It worked and was clean.  However when I added a bunch of other dummy code things weren't so smooth. And when I connected via Ethernet to monitor the system it was all over the place. Seems that Tx...

So is PWM with variable duty cycle and fixed frequency possible on WC8?

I want to use the WC8 to control a PWM Battery charger circuit.  So I would vary the duty cycle depending on battery charge (Bulk, Absorb, Float, Off). Not sure what the optimum PWM frequency is for solar battery charging but Ive seen some above 100Hz. I plan to purchase an new WC8 for this...

Any ideas on code that could maybe produce a TTL out PWM frequency 50 to 100Hz with adjustable duty cycles 0 to 100%?    Freq50hz-DC50%:      Delay 20                        # set 50Hz loop      Set OP1[10] 1               # on 50%      Goto Freq50hz       But lots of other PLC logic will need...

Just ordered one.. 

Yep, have to scrap the plan of using the WC to measure A/I's on different grounds. Even the differential ground PV-Bat calculation. Doing this makes the A/I's even on the same ground have some inaccuracy's. Maybe ground loops, noise, etc... To complex to figure it out.   Will just monitor the...

Yep, was playing around with a similar idea.   PV ground to Bat Ground is <0VDC when the PV voltage is higher than the battery, and >0VDC when the PV voltage is below the battery. So an inverter would only work if the PV was higher than the battery.  But really all I need to know is if the PV...

I have a cheap solar charge controller that seems to be common positive. I want to measure the PV and battery voltage using the WC8 analog ins. The WC8 runs off the battery side of the charge controller so the battery ground and WC8 ground are common. This works fine for collecting accurate...

I contacted Ross, he has some but shipping is unavoidable and pricey. Where else besides Amazon and Ebay can Webcontrol be found? How come its not at electronic sites like Sparkfun.com?

There's lots of TTL controlled mechanical relay modules available but why not MOSFET modules? What's the pro's and cons here?   PRO's:   MOSFET -Faster -Less operating power -Can use PWM   RELAYS -Readily available in 1,2,4,8,16 banks -Can switch AC -Can have DPDT, TPDT, etc..     I use Relay...

There unavailable on Amazon. Where else can I get a new WC8 board for <$40.

Is the WC32 A/I input scale 0-5V or 0-10V?  I couldn't find it in the documentaion.   Thanks

Yep, thats the relay board. I tested the 5V version. http://www.amazon.com/Generic-Channel-Module-Expansion-Arduino/dp/B00GGKHVBY/
