This repository contains some NodeJS code to insert Davis Vantage Pro2 observations into a Firestore database.
A WiFiLogger is required, which needs to call the Firestore HTTP function endpoint.
The function inserts the request body in the database and uses the utctime field to determine a unique document ID (ISO string).
There is also a Firebase Function that triggers when an observation is added, to calculate the maxTemperature for the day. This value is inserted into the maxTemperatures collection. This collection is required to stay within limits of the free Firebase plan.
Alternatively I created some experimenting code to run as a simple Express server, for example on a Raspberry Pi. See src directory. This server connects directly to Firestore. I use it to see if WiFiLogger is able to connect through local network.
To install dependencies, run in project root and functions dir:
npm installInstall firebase tooling:
npm install -g firebase-toolingRun npm run in project root and in functions directory to see what scripts are available.
Set GOOGLE_APPLICATION_CREDENTIALS environment variable to authenticate locally with Google Service Account to Firebase Admin SDK.
