Doing telematics separately seems a sensible approach.</li></ol></div><div><br></div><div>I was wondering about a hybrid approach. Some of the GSM units (like the SIMCOM OVMS uses) can run user programs alongside the traditional modem and have I/O. All the telematics could run on such a processor (always on) and an I/O line could be used to wake up the GEVCU if required. But, such an arrangement would be far from trivial and a stretch for a hobbyist approach. A dual-processor, dual-firmware, system is much more complex to maintain and keep up-to-date.</div><div><br></div><div>Regarding full linux boxes (like raspberry pi, beagle bone, etc), my concern is power consumption. It would be wonderful to have a linux base, but the overhead is horrendous.</div><div><br></div><div>Regards, Mark.</div><div><br><div><div>On 15 May, 2014, at 6:55 pm, Kevin Sharpe <<a href="mailto:kevin.sharpe@zerocarbonworld.org">kevin.sharpe@zerocarbonworld.org</a>> wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; font-size: 12px; font-family: 'Helvetica Neue', sans-serif;"><div><div>Hi Rob,</div><div><br></div><div>I’ll send a complete GEVCU 5 hardware list when I get a moment.
