Request for an example cfg showing how to connect mqttwarn to hosted owntracks

[dazzag24]

Would it be possible to add a sample config, or to document how to point mqttwarn to the owntracks hosted MQTT server at https://hosted.owntracks.org?

Thanks

Please explain what you are trying to do: we provided "Hosted" for our OwnTracks location apps basically. Why do you need to connect mqttwarn?

Hi,

Maybe I'm misunderstanding something, but here is what I thought:

I'm using owntrack Android on two phones pointing to the hosted owntracks broker.

I have pointed owntracks/recorder at this hosted broker so that I can have map based UI to show tracks and last location.

I am no interested in investigating some of the mqttwarn features (in particular the pushover.net integration), but I cannot figure out how to point the ini file at the hosted mqtt server. In particular I think the tls/pem cert will be tricky.

Am I barking up the wrong tree? or just not explained myself clearly in the original question?

Thanks in advance.

So I want to received events from hosted mqtt NOT post them to it. Make sense?

This page has the details you need in terms of username, password, and the TLS root certificate you will require.

Thanks. I have used the sample python program already so I know that it does work with hosted.owntracks.org.

However, while I can figure out what I need to enter for the host, username and port, it isn't clear how I can replicate the tls settings that the python example program uses:

client.tls_set('/path/to/ca-bundle.pem', cert_reqs=ssl.CERT_REQUIRED)

Using some inspiration from this cached google result: http://webcache.googleusercontent.com/search?q=cache:fk70a9D-k30J:jameswhale.net/mqttwarn/mqttwarn.conf+&cd=4&hl=en&ct=clnk&gl=uk

I think I need to see these settings in the [default] section of the ini file

ca_certs = '/path/to/ca-certs.pem' tls_insecure = False

However I cannot see anyway of passing in the "cert_reqs=ssl.CERT_REQUIRED" parameter. Not without editing the mqttwarn code in any case. These param presumably get passed down into connect() and hence to line 842:

if cf.tls == True: mqttc.tls_set(cf.ca_certs, cf.certfile, cf.keyfile, tls_version=cf.tls_version, ciphers=None)

Will it work if I emit the "cert_reqs" parameter and only set the "ca_certs" parameter?

In addition what protocol is required?

In the exmaple python the mqtt client is instantiated like this:

client = mqtt.Client(clientid)

whereas in mqttwarn it is done like so

mqttc = paho.Client(cf.clientid, clean_session=cf.cleansession, protocol=cf.protocol)

It isn't clear from the http://owntracks.org/booklet/tech/proghosted/ page which protocol hosted owntracks is using.

Have you tried it? Just set ca_certs and tls_insecure = False; that should do it.

I'll give it a go. Only able to test at home. http proxy prevents me testing at work

Looks like it also need this line: tls_version = 'tlsv1'
