How to use MQTT in Node-Red: basics, examples, tip & tricks

[@myozone]

Thanks for this, I've been using Node-red for years but nice to be reminded of the basics and also the newer Node-red changes.

[@corey8399]

Changing from single topic to dynamic was what I was looking for. Thanks for the video

[@ath0rus]

I have spent the last hour going around in circles trying to find a guide that shows hoiw to use mqtt (espically in Node red), I found this video and it seems really good (im only up to 1:13 lol)

[@captmulch1]

Excellent - and I didn’t know about mqtt explorer - exactly what I needed!

[@csongorvarga]

@captmulch1 yes, a must have free tool. Simple, yet is does everything you need.

[@7null]

Great overview for the new - like me

[@fsprtube]

To elaborate: Store data at 00:00, 00:01, 00:02, 00:03,..................23:00: and full day delta for kwh_produced, kwh_consumed, gas_consumed.

[@p23rodriguez]

Thank you for this video!!!!

[@Dr.SherazAslam]

very very nice video. appreciated

[@Dr.SherazAslam]

Do you prepared any video that can help storing data having multiple fields on the same topic? How I can store different fields in influxdb via node red. Now I’m able to store single value

[@jumadhaheri]

Nice this is great

[@itolond]

how do you start the mqtt server in node read?

[@csongorvarga]

You don't. MQTT server is completely different from Node-Red. That needs to be installed separately.

[@itolond]

@@csongorvarga ok i was looking for it , what is recommended for mqtt - local Lan (mocsa, hive?)

[@fsprtube]

Hi Csongor, nice videaos and keep up the effort. I have used the storing of data in csv files and it works great. For Sensors t his is great. I have a MQTT with meterdata and want to only store at the whole hr and at 00:00 Can there be a time/data functionality be added?

[@csongorvarga]

Thanks. Yes, there is an option. Store the data that comes in from the MQTT node in a flow variable. And have a separate inject node that runs every hour and fetch the data from the flow variable. It will contain the latest data as new data always overwrites the one came before.

Nice

[@mohsinjessa8951]

Just started watching this video...and first suggestion...first slide "Content" line "Connecting to the MQTT Broken" change broken to broker.

[@csongorvarga]

ahhh, thanks. Too bad it is not possible to change video on YT once uploaded.

[@vanderleisilvasantos5343]

Nice man, can you explains how to connect with Alexa

[@csongorvarga]

I there are a set of Alexa specific nodes, but I don't have any Alexa devices, so this is all I know.

[@bpetrikovics]

"Connecting to the MQTT broken" on the contents should be broker, probably :)

[@csongorvarga]

Did I say broken? Hahaha

[@ainaamarni2476]

Hi why is my mqtt in just keep connecting

[@csongorvarga]

On the right when you see your debug, go to the Configuration Nodes and check to make sure you don't have duplicate configuration for the same MQTT server. I had this issue once.

Way to much elaboration or unnecessary details
