How to use aggregator with observatory and server

[itdiscovery-bot]

Hi there Ruvnet - great project!!!

Having some difficulty unserstadning how to get to visualisation from the aggregator

Yep got 6 nodes, flashed with ids and td and tier 2 pointing to the aggregator host IP

Aggregator sees the data

Now how do I get the sensing server to use this aggregated data I am at a bit of a loss

any help appreciated.

Cheers

The data flow from aggregator to visualization is:

ESP32 nodes → UDP:5005 → aggregator → UDP:5006 → sensing server → HTTP:3000 / WS:3001 → browser UI

Step 1: Start the aggregator (it receives from ESP32 nodes on 5005, re-emits on 5006):

cargo run -p wifi-densepose-hardware --bin aggregator -- \
  --bind 0.0.0.0:5005 --forward 127.0.0.1:5006 --verbose

Step 2: Start the sensing server pointed at the aggregator's output port:

sensing-server --source esp32 --udp-port 5006 --http-port 3000 --ws-port 3001

Note: --udp-port 5006 (not 5005) — the sensing server listens on the aggregator's forwarding port.

Step 3: Verify the chain

# Check aggregator is receiving from nodes
# (look for "Received frame from node X" in aggregator logs with --verbose)

# Check sensing server has nodes
curl http://localhost:3000/api/v1/sensing/latest

# Open UI
# http://localhost:3000/ui/index.html
