Controlling Mobius enabled VorTech pump using 0-10V (and BLE)

Hey guys!

First of all, let me tank you all for the effort put up on this thread.

I really wanted to monitor/control my mobius devices from homeassistant so I started implementing something to be able the same level of control of the app.
Right now I have it tested on Radion Lights and Vortech pumps since it's the devices I have and it works. I'm gonna release version 0.2.0 of the integration that will allow to contact all devices via a single device (the current version that has to connect to every device). I'm trying to document everything so that if anyone wants to pick something up and implement it on a different way, at least they have documentation support.

For the integration to work, all you need to have is a bluetooth adapter integrated with homeassistant. I strongly advise setting up a ESP32 with bluetooth_proxy on the tank (or near it).

I finished writing a standalone python library (with the help of Grok Build) for the Versa and a companion Home Assistant integration. I have an MXM on my Apex, so I decided to write a fully functional Home Assistant integration that can control the Apex and all MXM connected pumps (Nero, Vectra, Axis, and Vectra). Since the MXM doesn't support the Versa (and I hate the scheduling options in the Mobius app), my Home Assistant integration allows you to define schedules allowing you to dose weekly on any day of the week you want (Monday, Wed, Friday). I don't have any of this published on Github yet, but as soon as I do and have these available in HACS, I'll create a new thread about them and link here. If anyone is interested before then, you can DM me and we can discuss early access.

Hi! I was just wondering how close you are to publishing this to GitHub/HACS. I’ve been trying to find a way to control my Versa pump for quite some time, and I was actually about to embark on doing exactly what you've done when I found this thread. If you’re still a ways out from releasing it, I can PM you as requested. I would love to try out the code!

Replied to your PM. I may decide to contribute my Versa code into the larger python-mobius library that @r3pek has published. There's no real reason for the community to have to support multiple projects as long as Carlos allows collaboration supporting PRs for active development.

Yeah, as @rsummer said, it's already available. https://github.com/r3pek/ha-mobius
