Store long-term weather records (such as high/low temperatures, maximum wind speed, and rainfall totals) in Home Assistant using standard helpers and automations.

Prerequisites

Before installing the automations, you need to create the required helper entities. Go to Settings > Devices & Services > Helpers in Home Assistant and create the following items:

Input Numbers

input_number.day_temp_max
input_number.day_temp_min
input_number.day_wind_max
input_number.highest_daily_recorded_rainfall
input_number.highest_weekly_recorded_rainfall
input_number.highest_monthly_recorded_rainfall
input_number.highest_recorded_temp
input_number.lowest_recorded_temp
input_number.highest_recorded_wind_speed
input_number.last_month_rain
input_number.rain_yesterday

Input Datetimes

input_datetime.day_temp_max_time
input_datetime.day_temp_min_time
input_datetime.highest_daily_rainfall_date
input_datetime.highest_weekly_rainfall_date
input_datetime.highest_monthly_rainfall_date
input_datetime.highest_temp_date
input_datetime.lowest_temp_date
input_datetime.highest_wind_speed_date

Installation

Create all the helper entities listed above.
Copy the automation files into your Home Assistant automations.yaml or include them via separate automation files.
Important: Open the imported automations and replace the placeholder sensor entities (e.g., gw1100a_v2_2_3_###) with your actual weather station entity IDs.
Reload your automations in Home Assistant.
