Tempo

Tempo combines a highly configurable clock with an optional weather summary in the status bar—you can run it as a clock-only module or pair it with live conditions. Clicking the module opens a rich menu with a calendar, hourly forecast, and a seven-day outlook.

What Tempo shows

• Status bar – current time (using your preferred clock_format) and, when weather data is available, an icon + temperature badge that match the current conditions.
• Menu – a resizable panel containing:
  • A calendar with month navigation and highlighted selections.
  • Current city, timestamp, weather description, feels-like temperature, humidity, and wind information.
  • A horizontally scrollable hourly forecast.
  • A vertically stacked seven-day forecast with dominant wind direction and speeds.

Configuration

Option	Type	Default	Description
clock_format	string	%a %d %b %R	Strftime-compatible format used for the clock in the bar and in the menu header. See the chrono formatting guide for placeholders.
formats	array	[]	Multiple datetime formats that can be cycled through by right-clicking the clock. When provided, clicking cycles through each format in sequence.
timezones	array	[]	Timezone identifiers that can be cycled through by scrolling. Supports both IANA names (e.g., "UTC", "America/New_York") and fixed offsets (e.g., "+00:00", "-05:00").
weather_location	enum	None	Determines which coordinates are queried when requesting weather data. Current geo-locates via IP using ip-api.com. Use the City variant to pin the module to a specific place. Use Coordinates to specify exact latitude and longitude.
weather_indicator	enum	IconAndTemperature	Determines what information about the weather is shown in the bar, valid options are None, Icon, and IconAndTemperature.
wind_speed_unit	string	null	Override wind speed unit for both display and API requests. Options: "Kmh", "Mph", "Ms". When omitted, derives from locale (Metric → Kmh, Imperial → Mph). Temperature unit is not affected.

City-based weather

[tempo]
clock_format = "%a %d %b %R"
weather_location = { City = "Rome" }
weather_indicator = "Icon"

Wind speed in m/s

[tempo]
clock_format = "%a %d %b %R"
weather_location = { City = "Stockholm" }
wind_speed_unit = "Ms"

[tempo]
clock_format = "%a %d %b %R"
weather_location = { City = "Rome" }
weather_indicator = "Icon"

Coordinates-based weather

[tempo]
clock_format = "%a %d %b %R"
weather_location = { Coordinates = [40.7128, -74.0060] }  # New York City

Clock-only mode

If you omit weather_location, Tempo renders just the clock and calendar UI—no network calls or weather widgets.

[tempo]
clock_format = "%a %d %b %R"
# weather_location left unspecified on purpose

Format Cycling

The Tempo module supports multiple datetime formats that can be cycled through by right-clicking on the clock. When the formats array is provided, right-clicking the clock will cycle through each format in sequence.

• If formats is empty or not provided, the clock uses the single clock_format string
• If formats contains entries, right-clicking cycles through them and the single clock_format is ignored
• The update interval automatically adjusts (1 second for formats with seconds, 5 seconds otherwise)

Example: Multiple Formats with Right-Click Cycling

[tempo]
# Fallback format (used if formats array is empty)
clock_format = "%a %d %b %R"

# Multiple formats that cycle on right-click
formats = [
    "%a %d %b %R",         # Mon 23 Dec 14:30
    "%Y-%m-%d %H:%M:%S",   # 2024-12-23 14:30:45
    "%d/%m/%Y %I:%M %p",   # 23/12/2024 02:30 PM
    "%A, %B %d, %Y",       # Monday, December 23, 2024
    "%H:%M:%S",            # 14:30:45 (updates every second)
    "%x",                  # Locale date (e.g., 12/23/24)
    "%X",                  # Locale time (e.g., 14:30:45)
]

Timezone Support

Tempo supports cycling through multiple timezones by scrolling on the clock widget. The timezones array accepts both IANA timezone names and fixed offset strings.

• IANA names (e.g., "UTC", "America/New_York") are used when the format contains %Z to show timezone abbreviations
• Fixed offsets (e.g., "+00:00", "-05:00") are used for numeric offset display with %z, %:z, etc.
• Scroll up/down to cycle forward/backward through the configured timezones

Example: Multiple Timezones

[tempo]
clock_format = "%a %d %b %R %Z"  # Include timezone abbreviation
timezones = [
    "UTC",
    "America/New_York",
    "Europe/London",
    "+09:00",  # Fixed offset for JST
    "-05:00",  # Fixed offset for EST
]

Example: Numeric Offsets Only

[tempo]
clock_format = "%a %d %b %R %:z"  # Show numeric offset with colon
timezones = [
    "+00:00",  # UTC
    "-05:00",  # EST
    "+09:00",  # JST
    "+01:00",  # CET
]

Modules placement

Add "Tempo" to any section in [modules] so it renders in the status bar:

[modules]
right = [ [ "Tempo", "Privacy", "Settings" ] ]

Defaults

[tempo]
clock_format = "%a %d %b %R"
weather_location = "Current"

Networking & privacy

• Tempo fetches location data either from ip-api.com (for Current), from Open-Meteo's geocoding endpoint (for City), or uses reverse geocoding from Nominatim (OpenStreetMap) to get location names for Coordinates.
• Weather observations and forecasts are requested from the Open-Meteo API every 30 minutes. Ensure ashell has network access.
• If an API call fails the module keeps showing the last successful reading and logs a warning.

Screenshot protection

The tempo module provides privacy protection for your location in the weather menu. By default, the location is visible.

To protect your privacy when taking screenshots:

• Click on the location text to blur it (shows as "•••••")
• Click again to reveal the location

This user-controlled toggle ensures you can quickly hide your location before taking a screenshot.

Tips

1. Include seconds in clock_format (e.g., %T) only if you need them—the module automatically increases the refresh rate when second specifiers are present.
2. Use City when running behind VPNs or privacy relays, so the weather is tied to a predictable location.
3. Use Coordinates when you need precise weather data for a specific location that doesn't correspond to a well-known city.
