20170111 - device online for 1 min @0948 - someone on roof?

20170112 - device offline at 1524, surprised if that's power? check

20170113 - device work @ 0933 briefly - see early-wake-theory below

           early-wake-theory:

            if device goes below 11.1V while sleeping then it won't wake on

            the RTC but will wake when the solar charger sees 12V again,

            at which point it will see that it ought be asleep unti 1100

            and so it dozes until then - possibly means that we're keeping

            the kerlink up after the eurotech has gone to sleep, otherwise

            why is the voltage still dropping?

            - I modified /etc/stopproc.sh to stop pbm and call ker-off

20170124 - took that out again, added code to pbm binary

           looks like that fix didn't do it, need to test

           some more when at node Monday

20170118 - fixed kerlink not powering off - both s/w and wiring!

           we re-charged unit from mains around 1400-1430, after

           that back to solar, hopefully voltage on 19th will

           behave

20170124 - validated that ker-off does remove voltage from kerlink

           power input; found a code path in pbm that wasn't 

           calling ker-off, testing of that needs to be finished

           when device has power again. Note: left device with

           sleeping only set from 1440 to 1455 so it'll wake 

           early on 25th (not likely to get more power today

           due to sun angle)

20170125 - eek, I'd put the ker-off code in the wrong place;-)

           fixed now I think finally

20170126 - seems to have worked out - node went down @1600

           on 25th with battery @12.52V, awoke on schedule 

           @1102 on 26th with battery @12.49V and weather was

           overcast all morning (that I saw:-) on the 26th,

           node is drawing about 0.9-1.1A around 11am

           probably only safe to fully believe stats from

           here on, though some info can be gleaned from

           earlier data no doubt

20170127 - there was a wake @ 10:02 - might be ok though, node

           went into long standby at 1459 on the 26th so was

           close to out of power (11.34V)

20170128 - looks like basil was rebooted about 17 hours ago 

           (around 1800 on the 27th?) (down is also down)

           so vpn wasn't up - not sure if client will connect

           before it's next reboot, hasn't so far after 5

           mins (vpn manually restarted @ 1140) I'm guessing

           there was a power off event

20170201 - basil reboot: there was a bridge0 that was ifup'd

           and that might be interfering somehow, took that

           down, we'll see @ 1100 if that helps, if not, I'll

           wanna go check unit physically (also could be 

           SIM card crap, check that too - SIM seems ok, has

           7GB and 8 days left) 

           Turns out that the SIM was not ok - the "add on"

           thing is not being used and the balance was down

           to 0.65c or actually maybe negative. Topped the

           fecker up.

           Clock was still on jan 29 today, odd - maybe

           rtc isn't working right? also that might interact

           with vpn, not sure - actually no, it was that

           the node thought it was 1600 on the 29th so it

           went to sleep, wonder when it'd have awoken if

           Kerry hadn't hit the physical switch?

           I have the kerlink boottimes.txt that could be

           used to fix the boot times and hence battery

           log of the loradtn node if we want

20170202 - odd timing - node woke @1047 - is power still being

           consumed?

           also odd vpn pattern - new client IPs every few

           minutes, check node's syslog later

20170206 - looks nominal at the moment, nice weekend weather

           helps:-)
