Este plugin no se ha probado con las últimas 3 versiones mayores de WordPress. Puede que ya no tenga asistencia ni lo mantenga nadie, o puede que tenga problemas de compatibilidad cuando se usa con las versiones más recientes de WordPress.



This Plugin is currently being upgraded – Please be patient.
Please note that currently LED-SITE-INDICATOR does not work on PHP8 or higher – the code is being upgraded to be compatible.

Setting up LED-SITE-INDICATOR is easy. Simply supply your MQTT broker’s details and configure which WordPress events should trigger messages.

A number of events are predefined. Simply check the right checkbox and fill in the message’s subject and text.

  • Pageview
  • User login
  • Failed user login
  • Post published
  • Page published
  • New comment

Other events can be added using the “custom events” section. This allows you to use any WordPress hook (actions and filters) to trigger messages.


  • LED-SITE-INDICATOR uses [phpMQTT]: by Andrew Milsted.
  • Based on original WP-MQTT plugin by roytanck:


  • PW-MQTT's settings screen contains the broker settings, allows you to set up common events, or specify your own.


  1. Upload the plugin files to the /wp-content/plugins/led-site-indicator directory, or install the plugin through the WordPress plugins screen directly.
  2. Activate the plugin through the ‘Plugins’ screen in WordPress
  3. Use the Settings->LED-SITE-INDICATOR screen to set up your broker and configure messages

Preguntas frecuentes

Can I use this plugin to subscribe to MQTT subjects?

I’m sorry, but no. This plugin’s purpose is to send messages to a broker, not the other way around. Subscribing to an
MQTT subject would require WordPress to remain active continuously, instead of running only when pages are being served.

Will this slow down my site?

YES, if your site uses PHP8+

LED-SITE-INDICATOR does it’s very best to only connect to the broker when needed, so it depends on the messages you configure.
Sending messages on events that occur very often may slow down your site. But MQTT itself was designed to have a very
low performance impact.

My site is acting funny, and I think this plugin has something to do with it

Please disable custom events and see if that makes a difference. If it does not, please deactivate the plugin to see if
that helps. If any of these steps fixes the issue, please post your findings on the support forums. I’ll try to
look into them.
