Mesh, why not bluetooth and how to use it

This product is not using bluetooth, this is an RF Mesh protocol.

• This is intended for a Home equipped with a mesh of sensors that are permanently logging data to a raspberry pi server (all doc and SW install explained)
• The user can then use his phone, tablet or PC to watch the data log from the raspberry pi webserver.
• Note as of today there is no Bluetooth mesh product on the market, once they arrive they'll be complex, power hungry and expensive.

Open source, Open Design

100% Open source Software and Hardware PCB design on the nRF52 github repo

Complete Framework

Full integration in an Open IoT Framework based on InfluxDB and Grafana, Extensive documentation on github and on the Home Smart Mesh website

Some more InfluxDB and Grafana config readme and other IoT Nodes on the IoT Frameworks

More Family products to come soon

• Dongle : Currently the buyer would have to re-flash his own dongle available on the market, the source code is provided, soon there will be ready to use flashed dongles for those who do not have a debugger.
• Buttons : a simple 3d printed ready to use dash button that can be customized as per the user wish
• Motion sensors : log the orientation of a vertical window or the angle of any rotary object, also publish motion notifications to the mesh.
• Firmware enhancement : With multiple dongles the users will be able to program different actions depending where the user is located using the RSSI feature captured from multiple mesh nodes, more on this to come soon
