RE: MQTT subscribe - FatMax - 31.01.2024
It looks like all the examples run inside the resident script. I would like to be able to send something through a separate function that is not in the resident script.
Do you have an example I can use, or nudge me in a direction?

First script here: https://kb.logicmachine.net/integration/mqtt-client/

I am testing the resident script with 0 sleep interval. It works fine, I receive messages and send messages through tagged grp objects. But let's say I have another function running in a script outside of this resident script.
Code:
function sendToMqtt(message)
-- the code to send something over mqtt on the already established connection --
end
-- script using the function
foo = 1
if foo<2 then
sendToMqtt('less than two')
endHow can I accomplish this without opening a new connection?

Just create a new connection, it's much easier this way.
RE: MQTT subscribe - FatMax - 31.01.2024
Yes, it is easy. But wouldn't this affect speed and performance? Let's consider 200 objects changing value within 5 seconds and I want all that data pushed up outside of the resident script scope?

Then use a resident script. The script can modified with an additional callback function per object (similar to mqtt_to_object_conv, but in reverse). It will transform the object value the way you needed before publishing it to MQTT.

I am sending large amount of data generated from functions. I can not store the data in an object and therefore need to send it directly to the mqtt broker.

Use a separate connection for publishing then.
