Anyone tried loading pfsense on a Zotac ZBox? The cd boots but the installer keeps complaining about a SCSI driver issue and fails. I tried both 2.2 and a few of the daily compiles just to check. All give the same issue.

Anyone else with a Pi on WIFI had their Wifi just go away? Been running a Model A on my desk for about 2 weeks now. Im still waiting for some parts and I have to build a case. It has a USB WiFi. Twice this week the wifi just dropped. I had to do an "ifup wlan0" to bring it back. Anyone else seen this? No errors in the logs, nothing really to say why it dropped. I think when I put this in its final destination I might have to go wired ethernet...

I''m building a Pi to watch the usage of my sump and well pumps. If I check power status every second, I don't want to actually store that many data points. I figured I would store only the change points (off to on, on to off). RRDTool doesn't seem the right way for this. Any suggestions? #raspberrypi

Well, you need to store a state every given period (hour), and then the change from that point at times...

Looking to see if anyone tried current sensing with a raspberry pi. Before I purchase two of these: http://www.amazon.com/SCT-013-000-Non-invasive-Current-Sensor-Transformer/dp/B008ASXVL4/ref=sr_1_1?s=industrial&ie=UTF8&qid=1420409783&sr=1-1&keywords=current+sensor I was hoping someone could offer advice on non-invasive current sensors. I am looking to monitor a basement sump pump and a well pump, high amp A/C power.   #raspberrypi  +Raspberry Pi

I got an USB->RS485 adaptor for my RasperryPi project on Amazon. It came with no documentation. I looked up the contact info for the vendor to email and ask for some spec sheet or something only to discover they sell a really wide variety of items from LED lights to dildos. Something tells me I am not getting a spec sheet.

I have the MFG number now, I can probably find something online somewhere. Hopefully it will solve the "connect the Pi to the scrolling board" issue.

Can anyone suggest a RS422 TO USB port for raspberry PI? Knowing someone personally tried it is better than picking blind on Amazon.com

This is for the traffic light?

It's not just relays you can connect to gpio?

Anyone have experience with these and a Raspberry Pi? http://amzn.to/1NxX06K I am trying to use it with a A-D converter and really I get nothing useful for readings. Tried a multimeter and the transformer but that too gives me nothing useful. End goal - I want to know when a 110V and a 220V pump is either on, or off. I don't care so much about the current draw I just want status.

I have a clamp current sensing tool you could borrow, but unless a load is big I've never seen it read well

Thanks to http://pyserial.sourceforge.net/shortintro.html#opening-serial-ports and the RaspberryPi, I now have a scrolling board I can talk to. Next up, the Traffic Light!  Eventually this will be hooked into either Nagios or OpenNMS, or whatever other monitoring system we decide to go with.
