ESP8266 Community Forum

Hi Friends,
I'm doing a 'SmartGarden' project using esp8266 nodeMCU width MQTT. It's working fine as I expect.

But, I have a doubt "Can we use MQTT without internet connection (Intranet)?".

I was confused with that. please help me.

My question is "is it possible to work MQTT without internet?" and if it is possible "How to achieve it?".

Thanks in advance

Do you mean the ESP only has access to intranet?

In that case it would be possible: just install a MQTT broker inside your intranet and use that instead of a broker on the internet.

I have Mosquitto https://mosquitto.org/ running on a Raspberry Pi on my home network. An interesting option would be to run the broker on a ESP8266 such as described in viewtopic.php?f=11&t=14534
