Help to read html code

[peyoe]

Hi,

Try this:

Code:

require('socket.http')
socket.http.TIMEOUT = 5
data = socket.http.request('http://192.168.1.238/en/phase1.html')

-- Check if response value is received
if data then
  -- Fetch values from HTTP response
  p_activa = data:match([[<td id="p_activa">(.-)</td>]])
  -- Remove units and trims leading and trailing spaces and decode to numberic
  p_activa = tonumber(string.trim(string.gsub(p_activa, "W", "", 1)))
  -- Write to KMX
  grp.write('1/1/1', p_activa)
end

BR,

Erwin

Hello @Erwin van der Zwart
Thanks for the script!!
I change the script in order to put the user and password and to change the output object (virtual byte floating point) see it:

Code:

require('socket.http')
socket.http.TIMEOUT = 5
data = socket.http.request('http://user:user@192.168.1.238/en/phase1.html')
log(data)

-- Check if response value is received
if data then
  -- Fetch values from HTTP response
  p_activa = data:match([[<td id="p_activa">(.-)</td>]])
  log(p_activa)
  -- Remove units and trims leading and trailing spaces and decode to numberic
  p_activa = tonumber(string.trim(string.gsub(p_activa, "W", "", 1)))
  log(p_activa)
  -- Write to KMX
  grp.write('32/3/1', p_activa)
end

But this doesn't work, looking to the log this is the output:



And this is the searched data read from the wibeee webpage, storeged on "data"

Code:

<tr>
     <td>Active Power</td>
     <td id="p_activa"></td>
</tr>

Any idea?

Thanks again.
