Soko,

polling may keep the car awake, that's also an issue on the Kia e-Niro IIRC.

Changing the PollState can only affect the car indirectly via the changed polls. Maybe you could add your code & a log?

Regarding the poll replies stopping, is that also reflected in a CAN log? Maybe the OBD gateway throttles if it sees too many requests? (Hopefully not…)

If the gateway does throttling: do you login to the OBD as a "tester" and keep the session active by periodically sending the "tester present" frame?

Regards,
Michael

Heya again,

I'm trying to develop a detection for when the car is off/locked but I'm encountering a weird phenomena:

Car is shut down and locked

OVMS connected

CAN poll for voltage (only one poll value active) with 30 secs fails with error (so far nothing weird)

Unlock the car via car-key remote

Poll succeeds and I'm switching from PollState=0 to PollState=1 where I poll every 2 secs

Lock the car via car-key remote

After 1 hour the polls still work and the car is active

Is something like this known from other vehicles? So basically my car never shuts down :(

Another secondary weird thing:
When increasing the time to 5 secs for PollState=1 the polls get no reply and after 20 secs I swap back to PollState=0.
BUT the second the PollState changes the car replies again...
Even more weirdness: When PollState=1 time is 10 secs and I swap back to Pollstate=0 after 40 secs the same thing happens! Immediately I swap to PollState=0 the car replies again.
As if the PollState switching somehow wakes the car up??!

Any ideas?

Soko
