Step1. Build a firware with TLS/SSL support
When buildig the firmware nodemcu-build tick the tls/ssl support checkbox. Firebase http call require transport layer security.
Step 2. Find the database secret

The secret key is located in project overview > settings > service accounts > database secrets
Step 3. Post some data
There’s a http request that sends data from nodemcu using the http module
http.post('https://bees-134b7.firebaseio.com/hive1/data.json?auth=<your_secret>',
'Content-Type: application/json\r\n',
'{"humidity":'..dhtHumi..',"temperature":'..dhtTemp..',"weight":'..hxWeight..'}',

print("firebase post status", code)
