Space after value ; check if zero about mi600 HOT 12 CLOSED

can you show me an example?
I have no zero in front?

pi@rp4:~ $ mi600 ip admin pw webdata_now_p
472 
pi@rp4:~ $ mi600 ip admin pw webdata_total_e
718.5 
pi@rp4:~ $ mi600 ip admin pw webdata_today_e
2.10 

from mi600.

soory my mistake also Space at end for wedata_now_p

but more simple because no floating point
root@DietPi:~# bash auslesen
!211 !
!211!

#request value
ACTUAL=$(/usr/local/bin/mi600 $host_pv $user $password webdata_now_p)
#remove Space at End
echo "!"$ACTUAL"!"
ACTUAL_NUM=$(($ACTUAL))
echo "!"$ACTUAL_NUM"!"

webdatal_total_e
also Space at end but more comlicate because of floating point

from mi600.

I also check if Webdata_total_e is 0.0 than Inverter not ready but ist maybe not for you
because i know my inverter has more than 0.0
but new inverter i think is over comlicate to check if 0.0 is really the first value or inverter is not ready

from mi600.

is my last commit ok now?

from mi600.

looks good but Space not solve

it also get worst

mi600 now webdata_now_p has a .0 part (floating point)

uninstall and rm-r

from mi600.

should be ok now, can you check it again?

from mi600.

sorry but still space at the end but floating point is now gone for wedata_now_p

root@DietPi:~# bash auslesen
!213 !

#request value
ACTUAL=$(/usr/local/bin/mi600 $host_pv $user $password webdata_now_p)
echo "!"$ACTUAL"!"
#remove space at end
#ACTUAL_NUM=$(($ACTUAL))
ACTUAL_NUM=$(echo $ACTUAL | sed 's/[[:space:]]*$//')
echo "!"$ACTUAL_NUM"!"

from mi600.

I do not have any spaces?

root@DietPi:~# mi600 192.168.xx admin xx webdata_now_p
196
correct no space
ACTUAL=$(/usr/local/bin/mi600 $host_pv $user $password webdata_now_p)
but thats simple parse/request why end space ?

from mi600.

the response should be +196+
please use the code above

./mi600 192.168.xx admin xx webdata_now_p

from mi600.

thanks

it is not your fault you could reverse the change because its some with parsing

from mi600.
