[Ovmsdev] new member interested in Kia Soul EV preheating

Hi Kyle,

I’m the one who made most of the Kia Soul-part of OVMS. I’m not active anymore as I seldom go for long trips with the Soul and therefore don’t need to use the OVMS regularly. A lot has changed in almost seven years 🙂 

The only way I can think of that might work to get the commands for remote heating, is to have someone with UVO-access to scan the CAN buses while turning on and of remote heating. Unfortunately I couldn't find any one able to do that.
I’ve got a diagnostic tool that can control the different parts of the HVAC, so I did sample some of the commands, but in the end I didn’t use them as I didn’t dare to mess with the HVAC manually.

Regarding the 12V-draining that Henrik mentions, waking up the in-car CAN bus systems is needed to read the state of anything when the cars is off, like the door-locks, if I recall correctly. Otherwise OVMS would be completely silent and «useless» when the car is off. I don’t know if any one has found another way around it.

Best regards,

> I stopped using OVMS in the Soul, because the maintainer of the Soul car module coded it, so that under certain conditions it wakes up the in-car CAN bus systems regularly, leading to an AUX battery drained to 5 Volts, and a car that cannot start (or even unlock). I don’t know if that has been improved since then.
