shell-executor read from file

---

hey guys,

i’m reading out a s0 kwh-meter which writes a number into a file (every watt it increases a number by 1), with a shel-execution sensor i get the value into pimatic easy over the stdout, but can someone please tell me how i can devide that stdout by 1000 so the shown number in pimatic are in kwh an not in wh

with this command in the sensor device i read the number

cat /var/strom/kwhcounter

Make a Variable with Type Expression.
Give it a Name $kwh_variable and in the Expression-Field put in something like
$wh_variable/1000

@Michael-Rudek excellent, that’s what I’m searching for, many thanks mate!
