Domoticz does not update sensor display Topic is solved

[willem9136]

I have a DHT22 sensor. It uses MQTT to talk to Nodered.
Nodered sends topic domoticz/in to Domoticz.
Checked with MQTTOOL the topic to Domoticz and this looks fine.
In Domoticz I created 2 dummy sensors. Temp and Humidity.
From that 2 virtual sensors IDX value xferred into Nodered.
The sensor data comes along every minute and I can see on my MQTT tool it’s in a
good format in the payload of domoticz/in.
When I execute this command line:
HTTP://<ip-domoticz>:8080/json.htm?type=command&param=udevice&idx=11&svalue=123
The sensor display will become updated.

Before this current setup I had things running with Nodered and Domoticz.
So I know where to look for.
Who can tell me how to troubleshoot this problem?

I can supply the screen shots of the various configuration screens.
Let me know what you need to see.

Let me know what you need to see.

What are the exact JSON strings (everything between { and } nodered sends?
How did you setup MQTT in domoticz?
What are the types / subtypes of the dummy sensors?

{ command: “udevice”, IDX: 11, svalue: “5.5” }

I did nothing in Domoticz to setup MQT.
It worked before with my smart-meter which also used Nodered.
I compared the json string format. Exactly identical.
Type sensor is Dummy
Sensor type Temperature

Is there no way to include screenshots in this thread?

[willem9136]

Sorry, I see how to,do,that....

I live in Holland as well. If you have TeamViewer you can have a look into the system.

I need MQTT hardware module active in domoticz

MQTT.png (123.23 KiB) Viewed 1053 times

and I need to send
{"idx": 11, "svalue": "5.5" }

to get it to work (case and quotes matter) and "udevice" is default

Where can I find this screen in Domoticz? Never seen before.

Works!

Thank a lot!
