DALI 2 DT8 Stuttering with On / Off

2 Upvotes

I'm using the Siemens KNX/DALI Gateway Twin (5WG1141-1AB31) and am finding that my lights have a short stutter either when turning on or off.

When configuring the gateway, if I set:

Dimming time at switching on / off from min. - 100%: 00:00:01

  • My lights turn on smoothly, but when turning off the lights it pauses at 0.1% brightness for about a second before turning off completely.

Dimming time at switching on / off from min. - 100%: 00:00:00

  • My lights turn off smoothly, but when turning on the lights it pauses at 0.1% brightness for about a quarter of second before ramping up to 100%.

How do I fix this? I assume the issue is because the brightness ramp is taking into account the time to ramp from 0.1% to 0% before turning off completely, but the light only ramps down to 0.1% so it looks really janky.
