Since new Domoticz API syntax - Node-Red --> MQTT --> Domoticz doesn't work

[raeymeister]

I read in https://www.domoticz.com/wiki/Domoticz_API/JSON_URL%27s that the API syntax has changed in the latest releases of Domoticz.

In the past, I created a lot of integrations through node-red, where I used following syntax to send a switchlight command to MQTT (topic: domoticz/in) to control my lights:

IN A FUNCTION NODE:

Code: Select all

msg.payload = {};
msg.payload.idx = 33;
msg.payload.command = "switchlight";
msg.payload.switchcmd = "On"
return msg;

I reformulated this to the new format:

Code: Select all

msg.payload = {};
msg.payload.type = "command";
msg.payload.param = "switchlight";
msg.payload.idx = 33;
msg.payload.switchcmd = "Off"
return msg;

But this doesn't work.

When sending above request from node-red,

I see following on MQTT:

domoticz/in {"type":"command","param":"switchlight","idx":33,"switchcmd":"Off"}

I get following error in domoticz log:

2024-01-19 18:22:15.482 Error: MQTT: Invalid/Unhandled data received! (Topic: domoticz/in, Message: {"type":"command","param":"switchlight","idx":33,"switchcmd":"Off"})

Here the node-red flow:

what is the correct syntax in a node-red function node, using the new API syntax, to generate an MQTT message to control lights in Domoticz, please?

The switchlight API did not change so your issue seems not related to the API change.
Check https://www.domoticz.com/wiki/MQTT#MQTT_to_Domoticz

[gizmocuz]

This is not the correct syntax, try this

Code: Select all

{
  "command": "switchlight",
  "idx": 33,
  "switchcmd": "Off"
}

Hi gizmocuz, many thanks for your response.

I get a lot of errors in my domoticz.log:

[WebServer] Deprecated RType (devices) for API request. Handled via fallback (getdevices), please use correct API Command! (IP nnn.nnn.nnn.nnn)

Doesn't this mean that I need to use the new syntax as described in https://www.domoticz.com/wiki/Domoticz_API/JSON_URL%27s ?

[waltervl]

Those deprecation warnings messages come from other wifi devices or other user interfaces like Dashticz or apps or even the Machinon theme that needs to be updated. There is no need to change mqtt messages, nothing changed here.

Did you search the forum as there are more topics about this deprecation warnings (Not an Error), see for example https://www.domoticz.com/forum/viewtopi ... 5&start=20

I got lots of these devices from the python presence detection script.

https://www.domoticz.com/wiki/Presence_detection

Had to change the "get devices" line to deal with it as my version of the script was still from an earlier version of this page.

Updated from 2022.2 version and see the same messages.

Yes i read that that is not an error but annoying

How can i find who is sending and what? And will it cause problems in the future?

Debug mode didnt help.

Better not hijack this topic for deprecation warnings. Please use topic https://www.domoticz.com/forum/viewtopic.php?t=40415
