I ask because we’ve taken up Elixir and we use MQTT (also with a custom RPC on top) to coordinate ag irrigation. But I’ve been very frustrated with the state of MQTT implementations on Elixir (or lack of good documentation). I’m wondering if I’ve just missed an obvious one. We currently use a fork of Tortoise, but it has some issues.

Feel free to contact me, details in profile.

We also use a fork of Tortoise, wrapped in some easier to integrate code (for our use case).

At first, we used an erlang lib emqtt, but it was left unmaintained and then removed from github. We had to switch to something else. Not completely happy, but it works for us

Which version of emqtt are you referring to? We are successfully using 1.11.0 (with AWS IoT Core), which I believe is the "blessed" version for elixir.

I do not remember all the details, but I think it was during the transition from MQTT 3.1 to 5.0. We only use 3.1 and the 5.0 code was not yet finished, emqtt had a hard coded a dependency with an old lib, which we wanted to upgrade. There were no hex package, it was pulled from github. And then the repo on github disappeared (or maybe moved?)

I will have a look at this new package, it looks promising

[joehosteny]

Ah, yes - we are pulling from the tag on GH. However, I believe the hard dependency on the older version of gun was fixed recently. IIRC, that was what prevented a proper package at the latest version from being on hex.

I was able to update to the latest tag of emqtt on GH (1.14.4), which was not previously possible. I don't believe there are any blockers now to a package on hex.pm, so hopefully this is made available soon.
