Read sensor value via MQTT

[CodeKek]

Sorry for the simple question, but I need your help.
My Tasmota device (Device1) with analog sensor sends every 300 seconds the value:
SENSOR = {"Time":"2023-12-03T15:56:16","ANALOG":{"A0":103}}
How can I force it to send within this intervall?
For a relay module (Device2) cmnd/Device2/POWER sends the state of POWER, but
cmnd/Device1/ANALOG or cmnd/Device1/A0 does not work.

Is it possible
a) request to send the sensor data or
b) change the intervall time per MQTT command?

Thanks for your help!

Interval time is the telemetry period. You can change it with the command Teleperiod.

You can also poll with command Status10

Thank you it works fine
cmnd/Device1/Status 10

Teleperiod works too, but 10 sec is too long.

Bad solution

If you need fast reaction, do it on the device itself using Rules or Scripting-Language

use teleperiod now

Telemetry data is not meant for fast reactions to things happening in a short time frame (the purpose for that mechanism is to follow slowly changing sensors like temperature). Still, barbudor already mentioned the command to poll data Status 10 - the space is important to include for it to work.

But indeed, use rules (etc) to pick up data at shorter intervals, but that's not very fast. Depending on the use case, there is also the option of configuring ADC Button, which is faster but not very flexible.
