Split values

Configuration
1

Hello
I am new too HA. I am trying write a simple yaml - read html output and put it into sensors

Output is:

“23;07;22;11;12;47;0000200131;SC5-IG1;000;000;000;000;187;063;000;000;”

And I need put values 187 and 063 to plyn_1 and plyn_2

Code is


- platform: rest
  scan_interval: 10
  resource: http://192.168.1.155/dataout.htm
  name: "Plyn_www"
 
- platform: template
  sensors:
    plyn_1:
      friendly_name: "Plyn1"
      value_template: "{{ value.sensor.plyn_www.split(';')[1] }}"
      unit_of_measurement: "imp"
    plyn_2:
      friendly_name: "Plyn2"
      value_template: "{{ value.sensor.plyn_www.split(';')[2] }}"
      unit_of_measurement: "imp"
2

try it out in Developer tools > Template

{{ states('sensor.plyn_www').split(';')[12] }}

Thanks. It works

And here is another direction of doing it within restful (you are using restful sensor)
RESTful - Home Assistant (home-assistant.io)

Now i works, experimental code is bellow:

  • platform: rest
    scan_interval: 10
    resource: http://192.168.1.155/dataout.htm
    name: “Plyn_MM”

  • platform: template
    sensors:
    plyn_0:
    friendly_name: “Plyn0”
    value_template: “{{ states(‘sensor.plyn_mm’).split(’;’)[12] }}”
    unit_of_measurement: “imp000”
    plyn_1:
    friendly_name: “Plyn256”
    value_template: “{{ states(‘sensor.plyn_mm’).split(’;’)[13] }}”
    unit_of_measurement: “imp256”
    plyn_celkem:
    friendly_name: “PlynCelkem”
    value_template: “{{ states(‘sensor.plyn_0’) | float(0) + states(‘sensor.plyn_1’) | float(0) *256 }}”
    unit_of_measurement: “implusu”
    plyn_diff:
    friendly_name: “PlynDiff”
    value_template: “{{ states(‘sensor.plyn_celkem’) | float(0) - states(‘sensor.plyn_temp’) | float(0) }}”
    unit_of_measurement: “implusu”
    plyn_temp:
    friendly_name: “PlynTemp”
    value_template: “{{ states(‘sensor.plyn_0’) | float(0) + states(‘sensor.plyn_1’) | float(0) * 256 }}”
    unit_of_measurement: “implusu”

I want make sensor with difference between actual an previous value. I am tried to use temp sensor value, but it does not work.

Thanks
