You want to store temperature readings from multiple rooms on a Raspberry Pi using InfluxDB. Which Python code correctly writes two points with tags and fields in one call?

Aclient.write_points([ {'measurement': 'temperature', 'tags': {'room': 'living'}, 'fields': {'value': 20}}, {'measurement': 'temperature', 'tags': {'room': 'bedroom'}, 'fields': {'value': 22}} ])

Bclient.write_points({ 'measurement': 'temperature', 'tags': {'room': ['living', 'bedroom']}, 'fields': {'value': [20, 22]} })

Cclient.write_points([ {'measurement': 'temperature', 'tags': {'room': 'living', 'bedroom'}, 'fields': {'value': 20, 22}} ])

Dclient.write_points('temperature', tags={'room': ['living', 'bedroom']}, fields={'value': [20, 22]})

Step-by-Step Solution

Solution:

Step 1: Understand data structure for multiple points
Each data point must be a dictionary with 'measurement', 'tags', and 'fields'. Multiple points are passed as a list of such dictionaries.
Step 2: Evaluate options
client.write_points([ {'measurement': 'temperature', 'tags': {'room': 'living'}, 'fields': {'value': 20}}, {'measurement': 'temperature', 'tags': {'room': 'bedroom'}, 'fields': {'value': 22}} ]) correctly uses a list of two dictionaries, each with proper tags and fields. Options A, B, and C misuse data structures or method parameters.
Final Answer:
client.write_points([ {'measurement': 'temperature', 'tags': {'room': 'living'}, 'fields': {'value': 20}}, {'measurement': 'temperature', 'tags': {'room': 'bedroom'}, 'fields': {'value': 22}} ]) -> Option A
Quick Check:
List of dicts for multiple points [OK]

Quick Trick: Send multiple points as list of dicts with tags and fields [OK]

Common Mistakes:

MISTAKES

Passing lists inside tags or fields instead of separate points
Incorrect method parameters
Combining tags incorrectly in one dict
