  <b>Define</b>
  <ul>
    <code>define &lt;name&gt; PHTV &lt;ip-address-or-hostname&gt; [&lt;poll-interval&gt;]</code>
    <br><br>

    This module controls Philips TV devices and their Ambilight via network connection.<br><br>
    Defining a PHTV device will schedule an internal task (interval can be set
    with optional parameter &lt;poll-interval&gt; in seconds, if not set, the value is 45
    seconds), which periodically reads the status of the device and triggers notify/filelog commands.<br><br>

    Example:<br>
    <ul><code>
       define PhilipsTV PHTV 192.168.0.10
       <br><br>
       # With custom interval of 20 seconds<br>
       define PhilipsTV PHTV 192.168.0.10 20
    </code></ul>
  <br>
  <br>
    <i>Note:</i> Some older devices might need to have the API activated first. If you get no response from your
    device, try to input "5646877223" on the remote while watching TV (which spells jointspace on the digits).
    A popup might appear stating the API was successfully enabled.

     <u>Note:</u> If you would like to restrict access to admin set-commands (-> statusRequest) you may set your FHEMWEB instance's attribute allowedCommands like 'set,set-user'.
     The string 'set-user' will ensure only non-admin set-commands can be executed when accessing FHEM using this FHEMWEB instance.

        <u>Advanced Ambilight Control</u><br>
        <br>
        <ul>
          If you would like to specificly control color for individual sides or even individual LEDs, you may use special addressing to be used with set command 'rgb':<br>
          <br><br>
          LED addressing format:<br>
          <code>&lt;Layer&gt;&lt;Side&gt;&lt;LED number&gt;</code>
          <br><br>
          <u>Examples:</u><br>
          <ul>
            <code># set LED 0 on left side within layer 1 to color RED<br>
            set PhilipsTV rgb L1L0:FF0000
            <br><br>
            # set LED 0, 2 and 4 on left side within layer 1 to color RED<br>
            set PhilipsTV rgb L1L0:FF0000 L1L2:FF0000 L1L4:FF0000
            <br><br>
            # set complete right side within layer 1 to color GREEN<br>
            set PhilipsTV rgb L1R:00FF00
            <br><br>
            # set complete layer 1 to color BLUE
            set PhilipsTV rgb L1:0000FF</code>
          </ul><br>
        </ul>

      <ul>
        <u>Advanced Ambilight+HUE Control</u><br>
        <br>
        <ul>
          Linking to your HUE devices within attributes ambiHueLeft, ambiHueTop, ambiHueRight and ambiHueBottom uses some defaults to calculate the actual color.<br>
          More than one HUE device may be added using blank.<br>
          The following settings can be fine tuned for each HUE device:<br>
          <br>
          <li>LED(s) to be used as color source<br>
          either 1 single LED or a few in a raw like 2-4. Defaults to use the middle LED and it's left and right partners. Counter starts at 1. See readings ambiLED* for how many LED's your TV has.</li>
          <li>saturation in percent of the original value (1-99, default=100)</li>
          <li>brightness in percent of the original value (1-99, default=100)</li>
          <br><br>
          Use the following addressing format for fine tuning:<br>
          <code>devicename:&lt;LEDs$gt;:&lt;saturation$gt;:&lt;brightness$gt;</code>
          <br><br>
          <u>Examples:</u><br>
          <ul>
            <code># to push color from top to 2 HUE devices<br>
            attr PhilipsTV ambiHueTop HUEDevice0 HUEDevice1
