Hello everyone,,

In a bushfire situation (Australia) embers can enter a home through the eves and smoulder for days before developing into a fire.

I am after a smoke detector without a built-in alarm that could detect the smoke under the roof before it breaks out into fire.

So far I have been pleased with the sensors from Xiaomi and wonder if anyone know of a similar sized unit for smoke detection?

I'm trying to find best suitable mesh protocol for a new project. Project area is an outdoor field and every node should be ~10 meters away each in a square-grid structure. Also nodes will be mount over rotatable metal plate which can reflect signals anywhere else.

In the past, I used ~500 ZigBee nodes (actually XBee s2c modules) in 12 clusters, and it didn't satisfy me. Because it had worked healthy by around 40 nodes per a coordinator, and it wasn't enough(or costy) to reach high node counts like 10k nodes. Every coordinator is a huge payload in my software system, so I want to reduce coordinator counts.

Now, for a new project, I decided to use "NCS36510" SOC and I going to create a tree mesh with this chips up to 10,000 nodes! In this project, I just want to achieve that, sending and reading data from this nodes periodically (few bytes per 10 secs for example) and update node's firmware remotely. So I need a robust protocol over 805.15.4 to use over these chips in lower coordinator/edge device as possible and not really need to be that fast.

Is it good idea to use 6LowPAN? Or do you have any other suggestion to success?

Thanks.
