Scrape help / multiscrape

Dear All
I am trying to scrape data from my inverter. It has a very simple webpage in html/txt fromat.
Here below the full code, obtained with wget

VL1=238.2</br>IL1=0.3</br>PowerGrid=0.1</br>VS1=330</br>VS2=331</br>IS1=3.9</br>IS2=4.0</br>PowerPV=2.6</br>VBatt=50.6</br>IBatt=-23.3</br>PowerBatt=-1.2</br>PercentBattery=90</br>ACinvTemp=46.0</br>BatteryTemp=32.5</br>PowerHouse=1.0</br>InvFlag=1071</br>

It looks to be a simple task, but really I am not able to scrape the values, for example the PV power equal to 2.6 kW!
Actually I am using scrape or multiscrape.

I wonder that since there is no html / css structur, this is not so standard

this is my actual yaml code for multiscrape

- resource: http://192.168.1.8/raw_data
  scan_interval: 20
  sensor:
  - unique_id: PVpower
    name: PV Power
    select: "br:nth-child(7)"
    unit_of_measurement: "kW"
    value_template: '{{ value_split("PowerPV=")[1] }}'

Can anybody help me?
Thank you for support

Marcello

The HTML is not valid, which might be the cause of your issue. However, I’m wondering if it will not work just by removing the select part of your configuration?
