tempest-cli — Hyper-Local Weather from Your Tempest Station

Query live weather data from a WeatherFlow Tempest station. Supports REST API access to current conditions, forecasts, and history via the cloud, plus local UDP broadcast reception from your hub on the same LAN.

Setup

1. Get a personal access token at weatherflow.com (Account → API Tokens)
2. Set it in your environment:

export TEMPEST_TOKEN="your-token-here"

The CLI reads TEMPEST_TOKEN from the environment. It also falls back to reading ~/.tempest.env if the env var is not set (for agent subprocesses that don't inherit env vars). --help and --dry-run work without a token.

Essential Commands

current — Current conditions
