hello.
strange because telegram custom code version 1 work fine
but this new one, impossible to make it working…
job vas correct, like my_telegramV2.poll
and custom was my_telegramV2
and inside python code, def poll():
all is correct.
also my token and bot_chat id, I put this from old one
you did update from this post ?
strange it is not working…
thanks

Remy_Tsuihiji · June 3, 2019, 4:59pm

me too
not working
but telegram version 1 work fine
strange

plord · June 3, 2019, 5:50pm

What v1 / v2 code are you referring to ?

Remy_Tsuihiji · June 3, 2019, 6:17pm

the v1 is the first one you post there few months ago
v2 is the new one, with gps, co2 and other feature

plord · June 3, 2019, 6:39pm

Ah. So v1 is -

# send message to telegram
#
def bot_sendtext(bot_message):

	send_text = 'https://api.telegram.org/bot' + bot_token + '/sendMessage?chat_id=' + bot_chatID + '&parse_mode=Markdown&text=' + bot_message
 
	requests.get(send_text)

and v2 -

# send message to telegram
#
def bot_sendtext(bot_message):
	send_text = 'https://api.telegram.org/bot' + bot_token + '/sendMessage?' + urllib.urlencode({'chat_id': bot_chatID, 'parse_mode': 'Markdown', 'text': unicode(bot_message).encode('utf-8')})
	requests.get(send_text)

So the change is using urllib.urlencode() - the intention here is to encode some characters ( such as the british pound sign ) as per api spec.

Maybe it works less well with other character sets ? Not sure.

What text ( exactly ) are you sending ?

Remy_Tsuihiji · June 3, 2019, 6:46pm

Thanks.

I did try the french text from my console with v2 -

peter26@Kona $  my_charge_status.bot_sendtext "Charge arrete. Derniere charge connu 10%"
16e737229d31f230c9d241ab498c8cb8:
  return: null

and got the message on my phone.

I also tried a re-copy and paste from github to my autopi config and still got the message on my phone.

So I’m still not sure why the v2 ( ie version on github ) doesn’t work for you.

Anything useful in the logs ?

Remy_Tsuihiji · June 3, 2019, 10:42pm

Ok.
So i will copy past this from GitHub too and doing test do be sure all is ok.
I will see the log too and tell you.
Thanks

Axel · June 10, 2019, 7:33pm

Hi,

I’m trying to get this working with the Ioniq but I’m not sure whats wrong…

Am i translating these wrong? 000_Rapid Charge Port CCS Plug 2101 {j:6}
From what I can tell the rapid charge should be 12:13, as in J
And &2^6 as in :6

These 3 all return 1 when the car is charing at a ‘normal’ plug.

 def get_charging():
        args = ['driving']
        kwargs = {
        'mode': '21',
        'pid': '01',
        'header': '7E4',
        'baudrate': 500000,
        'formula': 'bytes_to_int(message.data[12:13])',
        'protocol': '6',
        'verify': False,
        'force': True,
        }
        return (int(__salt__['obd.query'](*args, **kwargs)['value'])&128)/128

def get_charging_chademo():
        args = ['CCS Plug']
        kwargs = {
        'mode': '21',
        'pid': '01',
        'header': '7E4',
        'baudrate': 500000,
        'formula': 'bytes_to_int(message.data[12:13])',
        'protocol': '6',
        'verify': False,
        'force': True,
        }
        return (int(__salt__['obd.query'](*args, **kwargs)['value'])&64)/64

def get_charging_normal():
        args = ['J1772 Plug']
        kwargs = {
        'mode': '21',
        'pid': '01',
        'header': '7E4',
        'baudrate': 500000,
        'formula': 'bytes_to_int(message.data[12:13])',
        'protocol': '6',
        'verify': False,
        'force': True,
        }
        return (int(__salt__['obd.query'](*args, **kwargs)['value'])&32)/32

I’ve also had no success with getting the Ignition, that should be:
000_BMS Ignition BMS Ignit. 2101 {ay:2}

def get_carState():
        args = ['driving']
        kwargs = {
        'mode': '21',
        'pid': '01',
        'header': '7E4',
        'baudrate': 500000,
        'formula': 'bytes_to_int(message.data[53:54])',  # Ignition
        'protocol': '6',
        'verify': False,
        'force': True,
        }
        return (int(__salt__['obd.query'](*args, **kwargs)['value'])&4)/4

Any tips?

plord · June 10, 2019, 9:08pm

These seem reasonable to my eye.

I would try dumping the whole PID in the different cases. ie in the console -

obd.query test mode=21 pid=01 force=true

Steve · June 13, 2019, 9:53am

I had the same issue upon using the newer version. I watch the logs and discovered that I needed to delete the old persistent data file. Once I did that, it started working.

I do have one remaining issue that I wanted to make time to fix and open a PR for, and that is a bug where if you have multiple charge sessions without using the car between, all is well at the end of the first session, but on the second session you’ll receive a message per minute with incomplete data. I only notice this because I top up with solar power where possible, so don’t always complete a charge in one go.

plord · June 13, 2019, 3:56pm

Good catch, thanks. There is my_charge_status.delete for this purpose, I added this to the comment block in the script.

I’ve not seen this myself but I’ll keep an eye out for it.

plord · June 13, 2019, 6:30pm

So far I’ve been unable to replicate this -

Steve · June 19, 2019, 3:31pm

Turns out that the repeated charge thing was just coincidence. I think the actual issue may be to do with establishing location. Haven’t had a chance to dig in further yet.

Remy_Tsuihiji · June 19, 2019, 4:46pm

I had delete all of charge_status V1.
Now I use only the last version. V2

I will see if it is working or not.
But we have same car, so it should be ;).

plord · June 19, 2019, 7:20pm

Okay, could be related to the location. If you see this again pls get your logs ( especially any stack traces ).

Its possibly worth catching exception on nearest_charger() -

# get nearest charger
#
def nearest_charger():
    try:
        location = get_location()

        for charger in chargers:
            lat1 = radians(charger['latitude'])
            lon1 = radians(charger['longitude'])
            lat2 = radians(location['latitude'])
            lon2 = radians(location['longitude'])
            dlon = lon2 - lon1
            dlat = lat2 - lat1
            a = sin(dlat / 2)**2 + cos(lat1) * cos(lat2) * sin(dlon / 2)**2
            c = 2 * atan2(sqrt(a), sqrt(1 - a))
            dist = 6373.0 * c

            if dist < 0.02:
                log.info('found local charger '+charger['msg'])
                return charger['msg']

        log.info('https://api.openchargemap.io/v3/poi/?output=json&distance=0.1&maxresults=1&latitude='+str(location['latitude'])+'&longitude='+str(location['longitude']))
        result = requests.get('https://api.openchargemap.io/v3/poi/?output=json&distance=0.1&maxresults=1&latitude='+str(location['latitude'])+'&longitude='+str(location['longitude']))
        for i in result.json():
            return i['OperatorInfo']['Title']+', '+i['AddressInfo']['Title']+', '+i['UsageCost']
    except:
        log.info('Unable to get location')

    return 'No local charger found'

i am best than you, lol
look at this ->

Remy_Tsuihiji · June 21, 2019, 4:50pm

I update now for translation in French:
alslo km. but for this I only change “wltp” value to 449 km
maybe it is ok like that
