I've used Arduinos in conjunction with JMRI, but some more information would be useful to help diagnose the problem. ?E.g. what software are you running on the Arduino and how is it connected to JMRI? ?You've just upgraded to 4.14 - what from and was it working satisfactorily on that version? ?If sensors are not showing as Active are they showing as Inactive or Unknown? ?Is there a pattern to which sensors appear to work e.g. is it a range of system names that are effected? ?I think that there are differing versions of IRDOTs with direct (open collector) outputs or relays. ?Are yours electrically isolated from the Arduino by relays or are they directly connected?
