I want to do everything with Nerves but I run HomeAssistant with Zigbee2MQTT. There are too many integrations in place already and I have too many types of devices (beyond Zigbee).

If you only want to do very specific things with a select few devices it is probably feasible to talk to a Zigbee radio device like the sonoff and implement the bits you need but I think reliability takes a lot of iterations there.

I wanted the app, the notifications and so on. I may still end up doing automation using Elixir as described here:

I don’t relish learning to do that stuff in Home Assistant yaml.

And I have added a bunch of Nerves devices using Homex.

Home Assistant is such a mature project with so much functionality that unless you have a smaller scope in mind and want the practice it makes a ton of sense to use it.

Home Assistant OS actually looks similar to Nerves in terms of technical choices for the underpinnings. It does A/B partitions, Buildroot and all that

But keep us posted on what you end up doing.

I remember trying it many years ago it even then it felt as you described, so I have no doubts in that regard. My scope is small, but I’m sure it will grow with time too. I just want control, and no python haha

I got the device and I will at some point soon try to get it up and running. The first goal is to just add programmable control to my IKEA lamps (Zigbee on the box, though they claim only their hub will be able to control them), and see if I could make one of those “clap twice toggle lights” triggers somehow, as a fun project, though the long-term goal is to be able to control all lights and audio in the apartment through one interface.

My goal

The journey is the goal, and to do it with Nerves. I want to deepen my knowledge of Nerves and its ecosystem, and hopefully provide something useful for others while doing so

Another reason is that it will not “just” be a Smart Home Hub, but also do a lot of other custom things that Elixir does best, and where I want to minimise the image/container(s) as much as possible.

If I get something useful going with this, I’ll update here!

Cool! Go for it. Sounds great for learning

IKEA is bog standard Zigbee. If there are quirks they should be implemented in the zigbee2mqtt project already. For reference.

I have all my IKEA lights on off-brand Zigbee controllers.
