Leds on zencontrol smart switches can have mode configurations, target tracking configurations, and in some cases colour configurations. Configurations are only valid on ECD instances. Configurations will be written for the currently active LED profile except where specified. Where an instance does not support an LED, it will not answer to any queries.

Modes

Any values not specified are reserved and will cause undefined behaviour.

How To Query

1. Send ECD DTR1 = Instance number that the Led is attached to
2. Send eDali Command 0xBE<address>02
   • Where <address> is the ECD address byte as per IEC62386-103

How to Set

1. Send ECD DTR1 = Instance number that the Led is attached to
2. Send ECD DTR0 = Mode to set
   • The mode to set is a value from the above table in bits 7-1, and bit 1 being inversion
     • Target Status = 0x02
     • Inverted Target Status = 0x03
3. Send eDali Command 0xBE<address>12
   • Where <address> is the ECD address byte as per IEC62386-103

Tracking Bytes

Primary Target

This is used to track a dali targets status. The target should be the ECG address byte as per IEC62386-102 shifted right by one bit (address >> 1 = target).

How To Set

1. Send ECD DTR1 = Instance number that the Led is attached to
2. Send ECD DTR0 = Primary Target
   • The Dali102 address byte (as per IEC62386-102) right shifted by 1
3. Send eDali Command 0xBE<address>10
   • Where <address> is the ECD address byte as per IEC62386-103

How To Query

1. Send ECD DTR1 = Instance number that the Led is attached to
2. Send eDali Command 0xBE<address>00
   • Where <address> is the ECD address byte as per IEC62386-103

Listen Scene

This is used to track the active or last heard scene.

How To Set

1. Send ECD DTR1 = Instance number that the Led is attached to
2. Send ECD DTR0 = scene to track [0-15]
3. Send eDali Command 0xBE<address>11
   • Where <address> is the ECD address byte as per IEC62386-103

How To Query

1. Send ECD DTR1 = Instance number that the Led is attached to
2. Send eDali Command 0xBE<address>01
   • Where <address> is the ECD address byte as per IEC62386-103

Colour

Products that support colour Leds might support one of 2 colour modes. This can be discovered by querying the Leds colour where bit 7 will indicate a 7 bit colour mode if set, or 3 bit colour mode where cleared.

How To Query

1. Send ECD DTR1 = Instance number that the Led is attached to
2. Send eDali Command 0xBE<address>29
   • Where <address> is the ECD address byte as per IEC62386-103
   • Bit 7 will indicate 7 bit colour support if set, or 3 bit colour support if cleared.

How To Set

1. Send ECD DTR1 = Instance number that the Led is attached to
2. Send ECD DTR0 = Colour to set
   • The Led will only use the bits that it supports in DTR0 (0b111 or 0b1111111 depending on colour support)
3. Send eDali Command 0xBE<address>28
   • Where <address> is the ECD address byte as per IEC62386-103

3 Bit Colour

3 bit colour is a binary switch on a red, green, and blue LED. This allows the use of the following colour palette.

7 Bit Colour

The zencontrol 7 bit colour palette can be seen below where a value of 0 is the top left colour, iterating left to right, top to bottom. The 7 bit colour value corresponds to its index in this palette.
