Hi all,
I set up a basic monitoring system a couple of months back, using a raspberry pi as base station. It was all working fine. The pi came preloaded so I just plugged it in, found the ip address using Fing, and could then set it up using ip address/emoncms. All good.
About a week ago something went wrong and I can nolonger access the pi. I can't even find its IP address using fing. I have tried swapping ethernet cables, ports on my route, but no luck.
There is one IP address on fing which I can't identify, 192.168.0.2, "Cisco", could this be it? I seem to recall the name came out as "pi". When I try to access it (http://192.168.0.2/emoncms), it doesn't work.
I'm a bit confused now as to the setup for the Pi, as the instruction pages seem to have changed since I set mine up back in Aug/Sept.

Re: Raspberry Pi - stopped working, can't find IP address
It sounds you have had your SD card fail. This was a common problem when running a full emoncms logging server on the Pi. The SD card gets worn out. This is why we have changed to using the new gateway read-only file system. The change is explained in this post: http://openenergymonitor.blogspot.com/2013/09/raspberrypi-sd-cards-hdd-gateway.html. Another option would be to use a USD external hard drive with the Pi

Hi Glyn,
Thanks for the reply.
Are you saying that the SD card is dead and I need a new one (for either of the two options)?

Re: Raspberry Pi - stopped working, can't find IP address
Following this, if I understand correctly, for the Rock Solid Gateway approach, the next step is to write the firmware image onto a (possibly new) SD card. I have essentially zero raspberry pi knowledge, but I understand this would have to be done using an SD card reader, then put the card into the pi (i.e., I can't directly write anything to the Pi).

Hi Chris, yes unfortunately you will need a working SD card regardless of which option you use, as the RaspPi is configured to at least boot from one.
I would remove and test the card, see if it will re-format. If so, great.
If not....... well decide how you want to run your future system, and if it's just going to be to boot your rootfs (ie a USB HDD like mine), you will only need a SD card size of at least 128MB.
If you go for the gateway system - as per Glyn's post above, you will need at least a 4GB SD card.
