Hi,

in case of this thread: [Function question](https://discourse.nodered.org/t/function-question/36572/8)  
i have the problem, that my energy plug update his "sensor" very slowly. While in the webgui i can see live changed of volt and watt, i dont see it in mqtt. sometimes over 8 Minutes, while the watt changes 50 to 1. So the Solution is very delayed.

![grafik](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/b/8/b82793cf164f03a4babc87b2aa85d041477e65f8.png)

Can i trigger a Sensor update?  
Its a Tasmota flashed Plug.

Best Regards

If I remember rightly, you can set Tasmota to update as often as you like.

The first entry in a Google search of "tasmota mqtt interval" showed me.

I found it! -.- Logging settings are not only for console on webgui. the config is for mqtt to.

Thank you for your hint

...you can also keep logging-events and mqtt sensor-events separated by using a rule: [https://tasmota.github.io/docs/Rules/](https://tasmota.github.io/docs/Rules/)

Each change in sensor value can trigger a rule, that can be used to publish to mgtt separately from the log event: [https://tasmota.github.io/docs/Rules/#rule-trigger](https://tasmota.github.io/docs/Rules/#rule-trigger)

...and here are some examples you can build on: [https://tasmota.github.io/docs/Rules/#transmit-sensor-value-only-when-a-delta-is-reached](https://tasmota.github.io/docs/Rules/#transmit-sensor-value-only-when-a-delta-is-reached) or [https://tasmota.github.io/docs/Rules/#adjust-a-value-and-send-it-over-mqtt](https://tasmota.github.io/docs/Rules/#adjust-a-value-and-send-it-over-mqtt)

Note that the "tele-"\<sensor-.name\> trigger is equal to the Sensor logging event to console.  
A change of sensor value itself can be a trigger, so omit the "tele-" from the trigger name and use the Sensor name only (see docs regarding rules trigger, mentioned above
