@Tag Absolutely right.
Initially i was worried about losing sensor data with the clocks moving and then wondered about actions in this period.
I wonder if all controllers have the same issue or if one or more have a work around to mitigate the issue?
I'll have a look but have not much free time for a while now.
Or not at all in springtime when the clock will jump forward from 1AM to 2AM... that change in time will never see 1:30AM....
Time to get rid of DST 
@jkandasa Thanks that.
I guess that if something is set for say 01:20 then presumeably it would trigger twice in this situation.
I will keep this in mind if ever I have a situation where it might be an issue.
This weekend saw the clocks change by 1 hour in the UK and this got me wondering how mycontroller handles this situation.
Essentially at 2AM on Sunday the clocks are set back to 1AM.
So if an event was triggered at 1.30AM and then at 2AM the clocks go back to 1AM, will that event be overwritten and lost?
How does mycontroller handle this situation?
@fsgrazzutti I guess it all depends on the use you have in mind. For me I would like a panel to display and control in many rooms. The only way I can think of is to have a pi and screen with wifi and connecting to the main dontroller web server.
Before I didn't like to use wifi for security reasons, but now I have a radius server (running on a pi) I have 'enterprise' 802.1x that should be as secure as I need.
Maybe it is an option for your requirement too?
@fsgrazzutti This has been irking me too - I'd like a control panel in several places around the house, but there is no easy way to wirelessly connect them all to get the data that I can think of. All need to display data and allow commands to be sent (button push, slider etc.).
The simple solution would be to have multiple controllers, but then how to sync them up and transfer data/commands in such a scenario?
I don't have an answer, but you are not alone in wanting this functionality.
Intresting thing happened this weekend. The nodes all appeared 'down' again and yet in all screens (resources and topology) the GW was showing as up. It was a mystery. Then, I tried to turn on some lights, it worked.
So this time MyController is not getting data from the nodes, but is able to send commands to the nodes correctly. I am beyond puzzled by this as it is no longer a GW faliure nor is it a NRF24l01 lock up.
@jkandasa Logs sent and reply received.
One thing I forgot to mention was that upon a reboot of the pi, one GW would have the sensor of the other GW in it's list but without any details or data.
They GWs are on different RF channels 10MHz apart and different USB ports (USB0 and USB1) so I am not sure why this happens.. It is always the second GW that seems to get the 'ghost' data intended for the first GW, never the other way around.
@jkandasa Thanks for the response - I have had to reboot several time so would the logs still have what you want? IF so I can send to you.
Also it happens on either GW, not just one so I'll enable those logs for both if that's OK?
Maybe I next need to try the optiboot loader. Would it conflict with signing or encryption at all? AFAIK you can 'only' upload new firmware vie FOTA and not via a programmer once you take that step, is it true?
Does FOTA play nice with signing nodes and encrypted nodes?
Thanks 
Happened again and this time it just got a little more weird - now in resources it shows that the GW is up, data is received but the nodes and sensors show no data. But look at the GW in the topography view and it is down. Check again in the resources window and it shows as up. Now I am really confused!
