Please can you give a little more comments and explanations about the steps ( loops)

not all are so deep in bash and would like to improve bash skills as well.

I'm trying to include this script in a project " Volkzähler " visiualization of energy consumption for my home.

to do this it is enough for me to query the data every few minutes as in your script and send the values to the database via json request.

Translated with www.DeepL.com/Translator (free version)

i use your script for my upload data script for VZ-DB
i also add nowaday the total value

i had some Problems with the value maybe that also some idea/problem for your script to take in account

for actual power i had a zero in front

#request value
ACTUAL=$(/usr/local/bin/mi600 $host_pv $user $password webdata_now_p)
#remove Zero in Front
ACTUAL_NUM=$(($ACTUAL))


and for Total Energy i had a Space at the End

#request value TOTAL
TOTAL=$(/usr/local/bin/mi600 $host_pv $user $password webdata_total_e)
#Remove end SPACE-Char
TOTAL_NUM=$(echo $TOTAL | sed 's/[[:space:]]*$//')


Hi
Thank you for the script to get the inverter values.
It works perfectly.
How can I insert and bundle the information in iobroker.
I have seen that many types provide the same information.
Very nice work without having to access a cloud.

I would be happy if there is a possibility to import the data into Iobroker.

Greetings Andre

Hi,
thanks for the basic idea, I changed the script to something like this:

#!/bin/bash
host=$1
auth=$2:$3
FILE=$(mktemp)
trap "rm -f $FILE" EXIT
curl -s -u "$auth" "$host"/status.html > $FILE
grep "webdata_now_p =" $FILE | awk -F '"' '{print "Now:", $2, "W"}'
grep "webdata_today_e =" $FILE | awk -F '"' '{print "Today:", $2, "kWh"}'
grep "webdata_total_e =" $FILE | awk -F '"' '{print "Total:", $2, "kWh"}'

So you grab once the status to a temp-file, grep and awk it, and print everything at once. Or something like this:
pnow=$(grep "webdata_now_p =" $FILE | awk -F '"' '{print "Now:", $2, "W"}')
etoday=$(grep "webdata_today_e =" $FILE | awk -F '"' '{print "Today:", $2, "kWh"}')

more stuff as needed...

now=$(date)
echo "$now\t$pnow\t$etoday"

Is it possible that you add some extract string with the value but without extension Unit "W" or "kWh"

or a switch that that extract the 4 value and jump over your then
dat=$4
val=''
[ "$dat" = "webdata_today_e" ] && val=kWh
[ "$dat" = "webdata_total_e" ] && val=kWh
[ "$dat" = "webdata_now_p" ] && val=W
