We have a physical solution and the code is fairly trivial, but my main concern

cut). Clearly, this would
put the integrity of the data on the SD Card at risk.
Can anyone see any problems with this approach or suggest a better way?
Terry, to be honest the description of the requirement suggests the Pi
is overkill (IMHO), in my "intelligent"
pump controller project I completed when my house was being assailed by
flood wher I started with this
approach but ended up with a v.cheap arduino board. The code being in
on-board flash.
Opps that takes me off-topic for a Linux group :-)
Best regards,

I have a Stamp processor that could do it too, But Terry & Clive involved here
know linux, and probably don't want to learn another language, and also want it
supportable fo the future.
I have always understood that the way to power down the R-Pi is to
unplug it, and I have never heard about problems with the memory cards.
I suggest to always have a backup card available in case of failure in
any case.
For headless operation it is advisable to use a fixed IP address in case
you want to ssh into it, but on the basis of information given, it
sounds like it is standalone and not networked.
Cheers,
Peter
