EV car power management

Did you set the power settings for the dongle?
You can execute the command from the prompt to test, run the same that you have in the job.
Try that, it should show you what is in the returns and if configured sends the telegram message.
In the command prompt it will either show “sleep disabled” or “sleep enabled” if it works (and th edonglr is on line)

    if charging_ccs == 1 or charging_normal == 1 or soc != -1:
        disable_sleep()
        #bot_sendtext("sleep disabled")
        #bot_sendtext(power.sleep_timer)
        return {"msg": "sleep disabled"}
    else:
        enable_sleep()
        #bot_sendtext("sleep enabled")
        #bot_sendtext(power.sleep_timer)
        return {"msg": "sleep enabled"}

I think the names of jobs and packaged (custom code) can not have upper case or start with a number, stick to the names that I put there to start.
And obviously if it is sleeping then nothing works.

I have tested your code and settings on my IONIQ electric MY18 @AndersO, but i only got messages about AutoPi is going to sleep Screenshot_20190809-093202
No charging messages att all

AndersO · August 9, 2019, 4:56pm

@el93mon
Hej Mats,
I’m afk today til Sunday, with only my phone.
The script only enables our disables sleep. I have another script that send messages about charging. I can post that when I get back.
You should get messages with sleep enables as well though from this one. If the # is removed.

Not work for me at all.
I am novice and understand that i do something wrong but i don´t now what?
I test custom code direct in the prompt and get answer : ‘’‘import’’ is not available.’

el93mon · August 10, 2019, 11:34am

Hej Anders!

I thought something was missing, nice if you can share the code later.

AndersO · August 10, 2019, 7:27pm

Hej Mats.

Here is the code for the charging.
I just added the GOM range, but I cannot get the air temp, so I am using battery temp, I think it works ok, but not when the battery is warm from driving, the range is to long. I will try to get the air temp a bit more but if i cannot I will change that to a fixed value when the temp is above something like 22 degrees (then keep 22 when warmer), to be decided.

@jorgeli

If the code is installed you should be able to run it from the command prompt, not the complete code (I think that is what you tried to do) just the command to execute it (same as in the job), see screenshot:
38%20PM

At the moment i am charging and the return is “sleep disabled”

Hope this helps.

el93mon · August 10, 2019, 7:57pm

Thank you Anders, i will try it out!

jorgeli · August 11, 2019, 7:34pm

Thanks for you patience and help for me -)
Yes it works when write in prompt. It says sleep disabled
But the dongle are going to sleep anyway from power settings time.
So the script not working for me

el93mon · August 12, 2019, 9:26am

Now it works! Many thanks @AndersO

AndersO · August 12, 2019, 12:58pm

@jorgeli
Hi,
The script makes it stay awake when charging and when drivieng.
In all other cases sleep should be enabled and the dongle should go to sleep after 5 minutes (with the sleep timer set to 300).
Does your dongle sleep when the car is on, when charging or both?.

jorgeli · August 12, 2019, 7:10pm

The dongle is awake Only the 5 min when i drive or charge and then go to sleepmode.
So just follow the dongle power management.

AndersO · August 12, 2019, 9:03pm

@jorgeli, weird.
How often is the job running that executes the script?
I’ve set it to 6 minutes + run on start, the script sets the sleep to 5 minutes (300 sec) and the setting for the dongle is set to 5 minutes as well.
Does the job have the command properly written?
My guess would be that there is something wrong with the job.

If all is ok I think you need to ask support in that case, mine never goes to sleep while driving or charging. When turned off it does.

jorgeli · August 13, 2019, 4:12am

Hi Anders
Thanks again for feedback
Yes something i must have done wrong.
My config is like this:
custom%20code power Sleep%20job

AndersO · August 13, 2019, 2:08pm

@jorgeli
Hi, i think you are missing a space, for the Cron schedule I have a space after the 6 minutes: ‘*/6 * * * *’
Try that and see what happens

jorgeli · August 14, 2019, 7:06pm

Thank you very much I thing it work now

AndersO · August 14, 2019, 8:38pm

@jorgeli
Good to hear.
FYI there are spaces between all the stars, not sure you are aware of the and not sure it support it without stars.
the star are (* * * * *):

minute per hour
hour of the day
day of the month
month of the year
day of the week

ricard_ferre_jornet · August 14, 2019, 9:13pm

I’ve followed all your tutorial but I only received: car unlocked.
Do you know why? Thanks

AndersO · August 15, 2019, 4:18pm

@ricard_ferre_jornet
Hi, I am not sure i understand, car unlocked would be no return or message from what I posted.
The only things i have posted is to keep the autopi awake and to report via telegram on charging, both only hor Ioniq Electric.

AndersO · August 15, 2019, 9:04pm

New code for staying awake for the Ioniq BEV that works better and is smaller, it has to run at shorter intervals than the sleep timer.
I have it running every 2 minutes and the sleep timer is 300 sec (5 min).
The old code had to run at start and then at a longer interval than the sleep timer.
The new one can/should run several times within the sleep timer period.
What it does it just resets the sleep timer everytime it runs if charging or driving.
I think that the disable_sleep() can also be removed, but not 100% sure:
