@Stephan
Got the firmware updates now as stable and i have a question regarding the new ringactionState.
Currently my setup is as follows:
Ringing & door wires <> opener <> bell and relais in paralell (hue dimmer switch connected to the relais).
The hue dimmer switch gets “pressed” by the relais, my smarthome let alexa say “Someone ring the bell”.
So if RingToOpen is active, the opener is recognizing the ring and prevents the bell from ringing and (relais) alexa from speaking -> good.
I want to ditch the relais and dimmer switch and switch to the new ringactionState.
As i said i got the updates and did a log on an “someone unknown ring”:
2020.10.05 12:13:19 1: act_VR_Klingel_Nuki: ringactionState/event: ringactionState: 1 - state: online
2020.10.05 12:19:44 1: act_VR_Klingel_Nuki: ringactionState/event: ringactionState: 1 - state: online
2020.10.05 12:48:38 1: act_VR_Klingel_Nuki: ringactionState/event: ringactionState: 1 - state: online
2020.10.05 12:50:30 1: act_VR_Klingel_Nuki: ringactionState/event: ringactionState: 1 - state: online
Looks good this i can detect and use it as trigger and do my smarthome actions.
And the log when state is “rto active”:
2020.10.05 20:32:44 1: act_VR_Klingel_Nuki: ringactionState/event: ringactionState: 0 - state: rto active
2020.10.05 20:32:49 1: act_VR_Klingel_Nuki: ringactionState/event: ringactionState: 0 - state: opening
2020.10.05 20:32:55 1: act_VR_Klingel_Nuki: ringactionState/event: ringactionState: 1 - state: online
2020.10.05 20:33:21 1: act_VR_Klingel_Nuki: ringactionState/event: ringactionState: 1 - state: online
2020.10.05 20:33:25 1: act_VR_Klingel_Nuki: ringactionState/event: ringactionState: 0 - state: online
Sadly i get “ringactionState: 1” and the state is NOT “rto actve” so i cant prevent my smarthome actions because it seems like a “someone unknown has ring” 
As stated in the rest api docuimentation 20200902NukiBridgeAPI1_12.pdf ringactionState:
Flag indicating if a ring-action is currently occuring or not (reset after 30 seconds)
With the current behaviout i cannot distinguish between an “Someone unkown ring” and “rto active and opening ring occured”.
So my question is:
Am i doing something wrong or is this the expected behaviour of “rto active” and ringactionState if an RingToOpen was active before.
Thank you
