Functioning mesh of DK, Thingy:52, Feathers and Lamps - how to tap into it from Pi and interact with subscriptions/publications?

[HeneryH]

So i have my nRF5340 DK and have been pretty successful in getting my Mesh working with some Thingy:52 devices, some Adafruit Feather devices and some Sengled Lamps.

Groovy!

But now I want to tap into that Mesh and interact with things on the outside of the mesh.  Maybe the same type of things that come up when talking about a Mesh/Ethernet gateway. 

Or a MQTT bridge.  Or HomeAssistant integration.

All of those would be predicated on the core problem I have to tackle first is how to even subscribe or publish from a full blown os device like a Pi?

I already have a Pi4 with a recompiled kernel, BlueZ and meshcrl but I don't know how to tackle subscribing to some events.  I think meshctl was a good test case to make sure my Pi had the basics but maybe not what I need to subscribe to a network that is already created via a smartphone.

Any leads on where to find helpful docs?

Hi,

Do you want to use your Pi to be apart of the mesh or get mesh messages through a gateway via bluetooth for example?

Can you elaborate more? Im a bit confused to what you wanna achieve here.

I want to use an automation mechanism such as Node-Red scenarios/flow to act upon various stimuli from the mesh.

For instance, if a Device A publishes X and conditions A, B and C are true then I want to respond by publishing W to the Group.

So basically my Node-Red scenario needs to subscribe and publish via my pi.

In a non-mesh ecosystem there are some open source gateway servers that translate BLE Advertisements to MQTT.  Not that this is the answer here, but something similar.
