This basic project is to support multiple sensors to communicate via Node-Red to Domoticz.
Sensors
> ESP8862 \> MQTT \> Node-Red \> MQTT \> Domoticz
> The sample flow works fine till the moment that Node-Red has to update a variable in Domoticz.

The ESP is reading the DHT22 temperature sensor, brings it into the Node-Red flow and
there it stucks. The temperature_topic shows the right value in the msg.payload/debug screen.
The function node, with the following dscription, is not able to transfer the data into Domoticz.
msg.payload = {
"idx":29,
"nvalue":0,
"svalue":"12.1"};
return msg;
With the following statement in Putty I am able to preform that action with any problem.
mosquitto_pub -h localhost -m '{"idx" :29,"nvalue":0 ,"svalue":"99.0"}' -t 'domoticz/in'
Any idea what I do wrong?
Thanks in advance.

See anything different?

Colin,
The first statement in PUTTY works fine, it updates the Temparature variable in Domoticz.
The code in the Node-Red function gives no reaction in Domoticz.

domoticz/in and Domoticz/in' are NOT the same.

Yes, that works, but does
mosquitto\_pub -h localhost -m '{"idx" :29,"nvalue":0 ,"svalue":"99.0"}' -t 'Domoticz/in'

Colin,
Sorry, but the statement with the capital D in Domoticz doesn't work.
Any other ideas?

@Accelerator you are publishing to `domotiz/in` - but you are subscribed to `Domotiz/in`.
So Node-RED is subscribed to a _different topic_ to what you're publishing to.
Have you tried publishing and subscribing to the _same_ topic?

Or subscribe using the MQTT wildcard to see all published messages

Of course not, that is the whole point. You said that it works if you publish with a lower case d, but in the node red flow you are publishing with upper case D. Change the flow to use lower case and it should work.

Gentlemen thank you for the quick reponses, problem solved
