hubot-pollen

hubot-pollen

Retrieves the latest pollen forecast using Open-Meteo first, with fallback to Pollen.com when Open-Meteo has no usable pollen data.

Installation

In hubot project repo, run:

npm install hubot-pollen --save

Then add hubot-pollen to your external-scripts.json:

[
  "hubot-pollen"
]

Configuration

Set the target location by providing a default search value (ZIP, city, or place text). Defaults to Nashville, TN for demonstration purposes.

Environment Variable	Required?	Description
HUBOT_POLLEN_ZIP	No	Default location query (ZIP, city, or place)
HUBOT_POLLEN_OLLAMA_ENABLED	No	Set to true to register pollen tools with hubot-ollama

Commands

• hubot pollen - Show today's pollen levels for the default location query.
• hubot pollen <zip> - Show today's pollen levels for the given 5-digit ZIP.
• hubot pollen <search> - Show today's pollen levels for a geocoded location query.

Data Source Strategy

• Query Open-Meteo geocoding with the provided location string.
• Query Open-Meteo air-quality pollen endpoint by coordinate.
• If Open-Meteo pollen values are all null (or otherwise unusable), fallback to Pollen.com using a 5-digit ZIP when available.

Open-Meteo pollen values are only available for Europe during pollen season, so fallback is expected for many US locales. Slack responses cite Open-Meteo in the attachment footer when that data source is used.

Sample Interaction

user1>> hubot pollen
hubot>> Nashville, TN Pollen: 8.2 (Medium-High) - Alder, Juniper, Maple

user1>> hubot pollen London
hubot>> London, GB Pollen: Low intensity (1.7 grains/m^3 peak) - Grass 1.7, Birch 0.6

NPM Module

Ollama Integration

This package can expose pollen tools to Ollama for use in LLM-powered conversations through the hubot-ollama package.

Enabling Ollama Tools

To enable this feature, set the following environment variable:

HUBOT_POLLEN_OLLAMA_ENABLED=true

This requires hubot-ollama to be installed in your hubot repository. If hubot-ollama is not available, the tools will not be registered but the package will continue to function normally.
