- Build OS image with BSP distribution for Edge Node and save it to SD card. Insert SD card with BSP to RPi4 board and start controlling the board remotely.
[10 ~10 minutes] - Run local Edge Server on developer workstation with all needed services for software development and zero touch deployment.
[3 ~3 minutes]
- Connect/solder S-Soil MTEC-02B with USB to RS485 converter and insert into RPi4 board.
- Build a custom stack for S-Soil MTEC-02B to extract realtime data - Total Dissolved Solids (TDS), Temperature, Salinity, Volumetric Water Content (VWC) with python script, send data to Edge Server with Telegraf.
Deploy new stack remotely without touching the board to Edge Node (RPi4 board) from developer workstation.
Edge Server will collect data in InfluxDB and telemetry data will be available to display Grafana dashboard.
[4 ~4 minutes]

- Proprietary/open-source containerised services.
- Integrations with 3rd party PaaS/SaaS (AWS IoT, GCP IoT Core, Particle, etc.)
- More complex software frameworks (EdgeX, ORRA, Fledge, etc.) with own software updates and management tools.
Some open - source data exporters to consider are - telegraf, node-exporter, statsd, tcollector, collectd, cadvisor, promtail.
Stack can be single or multiple containerised services working together and incorporating designed business logic.
