hi any of you familliar with bash and or curl stuff eshwhy
i'm trying to integrate a sma ev charger and the peice of shit has no real api
i got sensor whit bash but am a bit stuck whit the controles
this is what i have now to try and get it to respond
IP_EV_Charger='11.3.3.8'

USER='xxxx'
PASSWORD='xxx'


TOKENREQUEST=$(curl  http://$IP_EV_Charger/api/v1/token -d "grant_type=password&username="$USER"&password="$PASSWORD)
bearer_token_string=$(echo "$TOKENREQUEST" | jq -r .access_token) # -r removes surrounding quotes
echo "$bearer_token_string" 

test=$(curl -i -s -k -X 'PUT' http://$IP_EV_Charger/api/v1/parameters/IGULD:SELF -H 'Content-Type: application/json'  -H "Referer: http://$IP_EV_Charger/webui/Plant:1,IGULD:SELF/configuration/view-parameters" -d '{\"values\":[{\"channelId\":\"Parameter.Inverter.AcALim\",\"value\":\"6\"}]}' -H "Authorization: Bearer $bearer_token_string")
echo "$test"
and this is the part that works 
IP_EV_Charger='11.3.3.8' ;

USER='xxxxx' ;
PASSWORD='xxxx' ;


TOKENREQUEST=$(curl --silent curl http://$IP_EV_Charger/api/v1/token -d "grant_type=password&username="$USER"&password="$PASSWORD)
bearer_token_string=$(echo $TOKENREQUEST | jq -r .access_token) # -r removes surrounding quotes

SMA_EV_Return=$(curl --silent http://$IP_EV_Charger/api/v1/measurements/live/ -d "[{\"componentId\":\"IGULD:SELF\"}]" -H "Authorization: Bearer $bearer_token_string")

echo "{\"sma_ev_json\":"$SMA_EV_Return"}"
```

What about if you try running the curl without it being in the bash script just to see what the outputs of each one are

What are the expected results?

stuck ferry
#

a paremiter in the charger needs to change so i can controle its maximum electricity draw but it is pretty locked down and has no decent api

vestal zenith
#

You see the 302 found near the bottom? That's a redirect, I think its saying that the new page is at the URL it gives you in the location on the second last line

stuck ferry
#

yeah that url is in the script but whitout httpS so i'l try that now

vestal zenith
#

Yeah or try repeat the curl command but changing it to the new one

stuck ferry
#

that gives this error ```

Hmmmm that is strange

stuck ferry
#

yeah

stuck ferry
#

yeah not really finding anything myself

rough garden
#

It's possible that they locked it down... I've got the Shell EV charger and I can only retrieve usage data without login. It's a login from them, I can't get into it...

#

Are you sure you can get into using the credentials you've got?

stuck ferry
#

yeah we installed it :p

rough garden
#

Isn't it possible to contact the manufacturar?

stuck ferry
#

yeah but they aren't really known for updates

#

it looks the same as it did 5 years age and 50 years from now kekw

have you tried with postman, i find it helps to decipher whats req'd a lot easier
