How to get a value (temperature) from www of device?
I’ve looked on the “https://www.home-assistant.io/components/scrape/”, but still could not get it to work.

I.e. the page looks like below.
I want the “8.75” value from this page.
See bottom of this page.

I’ve tryied below code in “config”, but no result…

sensor:
  - platform: scrape
    resource: http://xxx.xxx.xx.xx
    select: "Aktualna temperatura"

<head>
	<meta HTTP-EQUIV="content-type" CONTENT="text/html; charset=ISO-8859-2">
	<script language="JavaScript" type="text/JavaScript">
<!--
if (parent.main) {
	parent.location.href="/";
}
//-->
  </script>
</head>

I’ve tryied also:

# elproc LD100T temperature   
  - platform: scrape
    resource: http://192.168.1.200
    select: 'td:nth-of-type(22)'

But not getting the value. What I’m doing wrong?

The expected result should be ‘8.75’.

On other forum someone suggested following:

    name: sensor 8
    resource: http://192.168.1.200
    select: curl --silent http://192.168.1.200 | grep "Aktualna temperatura " | tr -dc [0-9].-

But in ‘hassio’ I’m not getting results.

However on the DOS ‘command line’ the commands is working - I’ll get what I want. Ex. ‘10.50’.

C:\>curl -k --silent http://192.168.1.200 | grep "Aktualna temperatura " | tr -dc [=-=][0-9].'

10.50

What is wrong in set-up of the ‘scrape’ sensor?

Of course - the answer was in question…
I should use ‘command_line’ sensor.
Now it works.
For someone looking advice this below is working.
Device “Elproc” LD100T.

# Temperature from Elproc LD100T
sensor:
  - platform: command_line
    name: External water supply
    command: 'curl --silent http://192.168.1.200 | grep "Aktualna temperatura " | tr -dc [=-=][0-9].'
    unit_of_measurement: "°C"
