Dimmer 2 - Not responding to switch or scene activation after long period of inactivity





I have a couple of Dimmer2 modules attached to single (toggle) switch and they work fine.

I have one Dimmer2 attached to a double toggle switch 2 wire setup.

It is the latter one that is causing the issues.


When it hasn't been activated for a while, it acts strangely.

Upon activation, either via switch, scene or within the app, it blinks for a split second, shortly followed by an attempt to turn on and then turns off again. Then I have to flip the switch a couple of times before it turns on completely. 


Then once it has been turned on it responds to commands perfectly.


I have turned parameter 20 to toggle.


Has anyone else experienced this before?


I forced it to to a auto-calibration again without success.


I have no spare modules lying around to give that a go unfortunately. I would rather try to solve this first before going out and buy more.


Thank you for your help.
