Publish in MQTT JSON format

[LeanzLatino]

Hey iam trying to figure out how to get publish MQTT json format that homeassistant and many more application use.

Iam using gps plugin and would like to use value in this format.
{"latitude": 50.601972,"longitude": 10.112339, "Altitude": 20.0, "Speed": 2}


Thank you in advance!

Let's say your task name is "gps" and your value names are the ones you use in your example. Then:

Code: Select all

On gps#latitude Do
Publish,<mqtt topic>,{"latitude": [gps#latitude],"longitude": [gps#longitude], "Altitude": [gps#altitude], "Speed": [gps#speed]}
Endon

Where <mqtt topic> is whatever topic you plan on using.

I thought the json string needed single quotes around the curly brackets... (in the recent ESP Easy releases)

Code: Select all

Publish,<mqtt topic>,'{"latitude": [gps#latitude],"longitude": [gps#longitude], "Altitude": [gps#altitude], "Speed": [gps#speed]}'

You're right! Thanks for that.

It doenst seem to change i have also tried.

On gps#latitude Do
Publish,%sysname%,: [gps#latitude],"longitude": [gps#longitude], "Altitude": [gps#Altitude], "Speed": [gps#speed]}
Endon

and also

On gps#latitude Do
Publish,coordinates,: [gps#latitude],"longitude": [gps#longitude], "Altitude": [gps#Altitude], "Speed": [gps#speed]}
Endon

I use same value that wiki recommend , i havent changed to Capital letters etc.

It doenst seem to change i have also tried.

Have you tried the example @dynamicdave gave? That uses the quotes around arguments containing spaces or commas, as required in current releases of ESPEasy

Your last examples have invalid JSON
