I am happy to share the latest Phable version now supports nhaystack without required external package dependencies.
In just a few lines of code Haystack tagged data can be retrieved from a Niagara device with nhaystack in a Pandas DataFrame as shown in the below example.
import os
from dotenv import load_dotenv
from phable import HaystackClient
# load environment variables to preserve secrets
load_dotenv()
URI = os.getenv("URI")
USERNAME = os.getenv("USERNAME")
PASSWORD = os.getenv("PASSWORD")
client = HaystackClient.open(URI, USERNAME, PASSWORD, content_type="zinc")
df = client.read_all("point").to_pandas()
print(df)
Please note Phable is still experimental and a considerable amount of code was recently added to make this happen. Feel free to submit any issues to the Phable project on GitHub here.
