define personal attribute (Name / Unit)

---

if is possible to create a new personal attribute in the config.json? i’m trying this with the shell-execute plugin

{
  "id": "benzin-e5",
  "name": "Benzin E5",
  "class": "ShellSensor",
  "attributeName": "cost",
  "attributeType": "number",
  "attributeUnit": "Euro",
  "command": "php -f /home/pi/scripts/benzin.php | grep BK | cut -d' ' -f2",
  "intveral": 3600000
},

but if i’m try to start pimatic the daemon crashed. if i’m changing cost to temperature it works but the number rounded to one decimal places.

do you want to have a graph to visualize the gasoline costs?
you could try it with "attributeType": "string",
but i guess then you are not able to log the values anymore, correct?

i dont need visualize the gasoline costs but i want to calc with rules

if its between 6-22 o clock and costs lower are $price-limit then send a mail

cool idea!!
would be nice if you share your script with us
if the variable is string you cannot calculate it, i guess.but give it a try.
you can set up the rule like "IF its after 6:00 and before 22:00 and $costs < $price-limit THEN do something"

it did not work. but i have a solution.

I’m setting up some variables, dummybuttons, variable devices, a dummyswitch and than i use a external script to update the variables. a simple rule trigger every hour the external script to update prices.

edit:

my php script (the reason why i’m using the lang is i could be write fast working code - normally is prefer bash)
