I believe it is expected to get that event when OVMS boots while the
car is idle since "not charging" is an accurate description of the
state.
I received a "not charging" notification on Sunday as well,
coincidentally as we were approaching home in our RAV4-EV. This
resulted from another "Alloca exception on core 0" crash and reboot of
OVMS:
Last boot was 170458 second(s) ago
Time at boot: 2018-07-29 21:41:32 GMT
This is reset #7 since last power cycle
Detected boot reason: Crash (8/14)
Crash counters: 2 total, 0 early
Last crash: Alloca exception on core 0
This is not the same time as yours (2018-07-29 17:55:36 PDT) so it
does not appear that the crashes are synchronized by some external
event.
Then today I looked at the iPhone app and saw that my OVMS had not
communicated with the v2 server for 15 hours. So I connected to the
USB cable again and found that the wifi was again in trouble. This
time there were many instances of a new error message from wifi that I
had not seen before, as shown in the log below.
Again I was able to restore operation of both server v2 and http by
"wifi mode off" then "wifi mode client".
