Run Python code from Phloem. The agent and Trellis can evaluate expressions and run snippets to process signals, compute values or drive custom logic.

#What you get

• Operations — eval (run an expression), plus a connection test.
• Each call runs in a fresh python -c process. Imports and variables do not carry over between calls.

#Setup

1. Install the connector from the Connectors tab and open its page.
2. Point it at your Python environment, then press Test to confirm.

#Computed channels

A computed channel runs your function over a window of a signal and publishes the result as a new channel. Your function gets one window:

Copydef my_metric(win):
    # win["t_us"] — sample times, microseconds since 1970-01-01 UTC
    # win["value"] — the sample values, same order
    return max(win["value"]) - min(win["value"])

Return one number, or a dict of names to numbers for several outputs. Times are microseconds; divide by 1,000,000 for seconds.

#Notes

• Put everything one computation needs, imports included, in one snippet.

#Connection fields

Every field the Add input form shows for this connector.
