LWT is missing #4

Closed jpmens closed 8 years ago

jpmens commented 8 years ago

Just a reminder that LWT handling is currently missing.

jpmens commented 8 years ago

Sorry, this is only half true: when I try and stop with CTL-C (#5) the LWT is then transmitted

devices/xxxxxxxx/$online false

However, $online true isn't emitted at start.

jalmeroth commented 8 years ago

Hmn, this is strange. For me this works as expected. Do you have any details here?

I will further look into the LWT thing, which I think is related to #5 as the thread is still running somehow.

jpmens commented 8 years ago

I definitely don't see it.

1466332655: New connection from ::1 on port 1888.
1466332655: New client connected from ::1 as xxxxxxxx (c1, k10).

1466332655: Sending PUBLISH to xxxxxxxx (d0, q0, r1, m0, 'devices/xxxxxxxx/$uptime', ... (2 bytes))
1466332655: Sending PUBLISH to xxxxxxxx (d0, q0, r1, m0, 'devices/xxxxxxxx/$signal', ... (3 bytes))
1466332655: Sending PUBLISH to xxxxxxxx (d0, q0, r1, m0, 'devices/xxxxxxxx/$online', ... (5 bytes))

The 5 bytes of $online are false upon killing the process.

mqttSetup isn't being invoked here ... I've added a couple of prints, but I can't say why not ...

$ pip3 install paho-mqtt
$ python3 jp.py

devices/xxxxxxxx/$online true
devices/xxxxxxxx/$name xxxxxxxx
devices/xxxxxxxx/$fwname (null)
devices/xxxxxxxx/$fwversion (null)
devices/xxxxxxxx/$nodes (null)
devices/xxxxxxxx/$localip 127.0.0.1
devices/xxxxxxxx/$uptime 0
devices/xxxxxxxx/$signal 100

😄

I see things with Python3 that I haven't seen with 2.7.

jalmeroth commented 8 years ago

mqttSetup gets invoked, when the mqtt-client calls the on_connect callback function. I have two systems running on Python 2.7 and paho-mqtt 1.2 that seem to work. May it be you are running on paho-mqtt 1.1?

If you enable the debugging mode on temperature_sensor.py logging.basicConfig(level=logging.DEBUG), you should see a message like DEBUG:homie.mqtt:connected: True. If you don't see that mqttSetup will not be called.

For some completely incomprehensibe reason I was indeed. My apologies.
