Is your feature request related to a problem? Please describe.
MQTT client connection to broker, and subscribe to specific topics

Describe the solution you'd like
It should me nice that you can post from tasmota mqtt values in json right to the AP and you can select the values you want to display on the screen

Describe alternatives you've considered
Now you have an Homeassistant or something with it

Additional context

This might be hard to realise for all APs because of flash limitations. So if somebody would implement it, it would be a feature not available on all APs. So it might be better to use an additional System like Home assistant for now.

I'm closing it as not planned for now. Feel free to reopen it or to implement this feature yourself if it is still required.

Hmm, I was looking at some mqtt stuff recently as well, and then came across this.

I'm curious - I thought MQTT was quite lightweight, and designed for low-powered IOT-type applications.

Or do you still need quite a bit of memory for MQTT usage? (I haven't done much ESP/Arduino dev work)

From a cursory search, I saw there's quite a few Arduino libraries for MQTT - e.g.:

https://github.com/256dpi/arduino-mqtt

And I think the ESP IDF includes a MQTT client as well?

Or is the idea also more steering people towards:
