Domoticz

By using NodeRed I can send an MQTT message to topic domoticz/in to update the Temperature meter.

I wrote a Python script which transmits exactly the same message with a dummy value (444) in order to recognize it.
The problem is that this message does not update the meter.

For preventing a timing conflict I delayed the transmission of the test message by 5 seconds.
So first the message from Nodered comes in and after 5 seconds the test message comes in.

With a MQTT tool I logged the MQTT trafic.
See the attachement for the catch of the 2 MQTT messages.
They look exactly equal.
For some reason the value of 444 is never displayed on the meter.

Who can tell me why?

Can you share the Python script and the domoticz log? When I test with it just updates the sensor.
If the host and/or the topic look OK in your Python script, it might be a non alphanumeric char playing tricks somewhere in the MQTT message.

Here python script and a tail of the log file.

You use topic domoticz.in and domoticz listens to domoticz/in

Stupid me......

Works!
Thanks a lot Waaren.
