Used ChatGTP for this:

Code:

url = 'https://www.havochvatten.se/badplatser-och-badvatten/vattenprov-badtemperatur/vattentemperatur-och-kvalitet-pa-badvatten-pa-sydkusten.html'
data = require('socket.http').request(url)

-- Function to extract the temperature for a specific location
local function extractTemperatureForLocation(html, locationName)
    local locationStartIdx, locationEndIdx = html:find(locationName)
    if not locationStartIdx then
        return nil
    end

    local temperatureStartIdx, temperatureEndIdx, temperature = html:find("(%d+%.%d+)°C", locationEndIdx)
    if not temperatureStartIdx then
        return nil
    end

    return temperature
end

-- Location name to search for
local locationName = "Yngsjö havsbad"

-- Extract temperature for the specific location
local temperature = extractTemperatureForLocation(data, locationName)

if temperature then
    -- Print the extracted temperature
    --log(locationName .. " temperature: " .. temperature .. "°C")
      grp.checkwrite('10/5/101', temperature)
else
    log(locationName .. " temperature not found.")
end
