Hi 
I built a custom integration that brings comprehensive weather, hydrological, and warning data from IMGW-PIB (Polish Institute of Meteorology and Water Management) into Home Assistant.
There are a few existing integrations that tap into IMGW-PIB data, but none of them aggregate this much information in one place. My integration pulls from 5 different IMGW-PIB API endpoints and exposes 24 sensors covering synoptic weather, meteorological observations, hydrology, and both meteo and hydro warnings - all in a single, configurable package.
What does it do?
The integration connects to the publicly available IMGW-PIB API and provides:
Synoptic data (6 sensors): temperature, wind speed & direction, humidity, precipitation, atmospheric pressure
Meteorological data (8 sensors): air & ground temperature, average/max/gust wind speed, wind direction, humidity, 10-min precipitation
Hydrological data (4 sensors): water level, water flow, water temperature, ice phenomenon
Meteo warnings (3 sensors): active warnings count, max warning level (1-3), latest warning with full details in attributes
Hydro warnings (3 sensors): active warnings count, max warning level, latest warning with full details in attributes
Key features
- Config Flow UI - set up entirely through Settings → Integrations, no YAML
- Autodiscovery & manual setup — the integration can automatically detect nearby stations, or you can manually select a specific station from the list
- Meteo warnings by district - you can filter warnings down to your county (district) level using TERYT codes, so you only get alerts relevant to your area
- Options Flow - change station, region, or update interval at any time without removing the integration
- Multi-instance - add the integration multiple times for different stations or data types (e.g., one for your local synoptic station, another for a nearby river)
- Polish & English translations

Use case examples
Flood monitoring - set up hydrological sensors for a nearby river and create automations that alert you when water levels exceed thresholds.
Severe weather alerts - use meteo warning sensors filtered to your powiat to get notifications about storms, heavy rain, frost, or heat waves before they hit.
Weather dashboard - combine synoptic and meteorological sensors for a detailed local weather overview on your Lovelace dashboard.
Automation example - trigger notifications when a new meteo warning appears:
automation:
- alias: "Meteo warning notification"
triggers:
- trigger: state
entity_id: sensor.meteo_warnings_max_level
from: "0"
actions:
- action: notify.mobile_app
data:
title: "⚠️ Meteo warning!"
message: >
Warning level: {{ states('sensor.meteo_warnings_max_level') }}
{{ state_attr('sensor.meteo_warnings_latest', 'description') }}

This is primarily aimed at Polish users since the data covers stations in Poland, but the integration itself supports both Polish and English UI.
