Hi all,

Probably a simple question, but i’m strugling with it.
What is the json string I need to create and push through MQTT to update a text dummy text sensor with a new text?

Thx

Ralph

from this wiki page

http://domoticzIP:domoticzPORT//json.htm?type=command&param=udevice&idx=IDX&nvalue=0&svalue=TEXT
IDX = id of your device (This number can be found in the devices tab in the column "IDX")
TEXT = Text you want to display

Thx @waaren, but thagt is not what I'm looking for. I found and tried the API call from a browser. This is working fine. I want to push the data through MQTT, so I need to create a JSON string. I tried:

Code: Select all

{"text":"home","idx":229}

and

Code: Select all

{"svalue":"home","idx":229}

and

Code: Select all

{"data":"home","idx":229}

Neither of these work.

Thx

maybe this will help

from old topic on this forum

I think you mean: mosquitto_pub -h 192.168.1.120 -t 'domoticz/in' -m '{"command": "udevice", "idx": 19, "svalue": "Test Test Test"}'

The correct syntax is indeed:
{"command": "udevice", "idx": nnn, "svalue": "your text"}
I use a NodeRed function to update my location (latitude in this example) to a text sensor and there I use:

Code: Select all

msg.payload = {"command": "udevice", "idx": nnn, "svalue": String(msg.payload.lat)};

Thx @waaren and @D'rMorris for the anwers,

however it does not seem to work. I'm also using NodeRed. It creates:

Code: Select all

{"command":"udevice","idx":229,"svalue":"unknown"}

However when pushed to Domoticz/in, nothing happens.
I dubble checked the idx twice.
For reference, this:

Code: Select all

{"command":"switchlight","idx":218,"switchcmd":"On"}

works perfectly. Its in the same NodeRed flow as the text change above. So imho the flow from NodeRed to Domoticz works.

Edit: For reference, I'm on the last stable version: 3.8153

What am I overlooking here?

Thx again!

What happens if you update the text sensor first with an normal URL JSON?

As reference, this is my script in NodeRed:

Code: Select all

msg.payload = {"command": "udevice", "idx": nnn, "svalue": "test")};
return msg;

I'm also runinng the stable version.

Just to be sure: you are sending data to domoticz/in (all lowercase) right? Perhaps you can create an inject input, then a script function and then the MQTT output and a debug node? And then try to debug this way?

@D'rMorris sometimes life is simple and an error easily overlooked. domoticz/in instead of Domoticz/in was thé golden tip!
Thx!!

Very welcome, glad you got it sorted out! Since the other flow was working, do you have multiple MQTT configutations defined? I have only 1 domoticz/in configuration and all my flows use that one.

Same with me, I only use domoticz/in. As mentioned before, I also use NodeRed and a Mosquitto broker on a (separate) Pi. For now I mainly pull in Owntracks positioning information for my "anyone at home" scenario's.
