Shared Runtime Location and Light

Use this page to configure the shared runtime parameters that depend on geographical position, light level, or astronomical offsets.

Use these settings only when the installation depends on geographical position, light level, or astronomical switching.
Enter location values carefully, because small coordinate errors can shift calculated switching times.
Use this page for the shared location and light layer only; product-specific behaviour still belongs on the relevant product page.

Overview

These parameters are shared because the same runtime may use them across multiple lighting, monitoring, and automation concepts.

Use LGTLAT and LGTLON together so location-based functions use the correct coordinates.
Verify the installation location carefully. Small coordinate errors can shift astronomical switching times.

Use latitude as the north-south position for astronomical calculations and location-aware runtime functions.

Parameter	Index	Range	Format	Default	Example
`LGTLAT`	-	-90000000..90000000	Latitude multiplied by 1,000,000	55900540	`LGTLAT 55900540`

Use longitude as the east-west position for astronomical calculations and location-aware runtime functions.

Parameter	Index	Range	Format	Default	Example
`LGTLON`	-	-180000000..180000000	Longitude multiplied by 1,000,000	9393530	`LGTLON 9393530`

Use LGTLUX when the runtime function depends on a measured light level instead of only astronomical time.
Choose the threshold based on the physical sensor and the real installation environment.
Practical example: use 80 for an 80 lux threshold.

LGTLUX

0..25000

0 = Disabled

>0 = Lux threshold

LGTLUX 80

Use LGTOFFSET to shift a calculated astronomical event earlier or later.
Negative values shift earlier. Positive values shift later.
Document the reason for any non-zero offset so the behaviour is understandable during service.

Parameter	Index	Range	Format	Default	Example
`LGTOFFSET`	-	-6..6	Offset step	0	`LGTOFFSET 1`

Set LGTLAT and LGTLON before enabling any function that depends on astronomical calculations.
After changing coordinates or offset values, verify the resulting switching behaviour against the real installation.
Only use LGTLUX when a real light sensor is installed and its threshold has been tested on site.
