This is my project weather station built with a Particle Photon and Sparkfun
weather shield (and meters). That POSTs data a Node / Express / MongoDB
server. That server also will be the API which the React PWA will query for
data.
First thing you need to do is flash your Photon with the firmware that's inside
of firmware/weatherstation.ino. Be sure to update this
line
with your own server's hostname.
After the Photon is flashed, you should deploy this server to where ever you want or expose your local server via ngrok.
Now go to [YOUR_SERVER_URL]/weather with the Photon connected to power to see
if data is being collected properly.
Document how to setup server, run client, etc. Very much WIP right
now. Check the package.json scripts for hints
