I use the example from https://github.com/mattjgalloway/openenergymonitor-emonhub/blob/emon-pi/examples/control_sender.py
In this post I found the structure for the data:
As MQTT topic is documented as :
[basetopic]/[node]/[keyname] i use
emon is the base topic (found in the docu)
Whats about node and keyname? Must they defined in emonhub.conf like:
[nodes]
[[12]]
nodename = MQTT1
hardware = MQTT1
[[[rx]]]
names = M1
datacode = 0
scales = 1
units = C
?
For this usage the python code should be:
client = mqtt.Client(“P1”)
client.connect(“127.0.0.1”, 1883, 60)
client.loop_start()topic = “emon/12/M1”
payload = “1,1850”
client.publish(topic, payload=payload, qos=0, retain=False)
client.loop()
But there is no data shown in Input as well as no data arrived in the log:

MQTT is running, password set in emonhub.conf. I have no idea how to publish my data. Please, can someone send the necessary, missing line of code?
The log of mqtt has:
('log: ', u"Received PUBLISH (d0, q0, r0, m0), ‘emon/12/M1’, … (6 bytes)“)
('log: ', “Sending PUBLISH (d0, q0, r0, m45), ‘emon/12/M1’, … (6 bytes)”)
('log: ', u"Received PUBLISH (d0, q0, r0, m0), ‘emon/12/M1’, … (6 bytes)”)
('log: ', “Sending SUBSCRIBE (d0, m46) [(‘emon/12/M1’, 0)]”)
('log: ', “Sending PUBLISH (d0, q0, r0, m47), ‘emon/12/M1’, … (6 bytes)”)('log: ', ‘Received SUBACK’)
