…so ST oddly limits new members to only three replies per topic, which means I can’t continue the conversation in-line (but can edit old posts). This makes no sense to me as someone looking for a fix, but here’s hoping this gets read!
Thanks for your continued help. Tried changing a combination/both those parameters, but still no joy. No response to the dimming function, and it defaults right back to 100% brightness once I exit the “dimming bar” interface, regardless of a lower % setting.
Strangely, sometimes the lights will “dim” gently to full capacity after calibration, but that’s the only time it will do that — otherwise it’s full-on 100% on or off…
Here is a sketch of the wiring. The light switch that the module should be controlling is on the left, with the yellow arrow…
_Thank you Robin— super helpful. Did this and the state shown in the app is now always correct, great news! However, although now the app turns the light on and on perfectly, it is still failing to dim the light fitting. Also, despite being put on the roller blind setting, the physical switch doesn’t control the fitting properly either. _
