Hi Drew ,
Thanks for your response.
The events logs show the times and dates accurate events but only for a matter of mins. for example if I restart openhab on the pi while logged into my.openhab after a 2 mins refresh the page and about 6 events are there all within a minute eg temps of rooms, switch on off etc but if you wait another 2 minutes and refresh there is no more new events. but within the events.log(on the pi) they continue to update.
so all points to persistence I though but myopenhab.persist is there and loads at start up and my cloud has always worked with or without it ie habdroid remote url access.
My work around at the moment is using notifymyandroid to push notifications I want to IFTTT which in turn can do other stuff.
I appreciate the suggestion of the resources I will need to check the pi as im running a couple of brokers and some opencv face detection but maybe the brokers are causing an issue or some random memory leak…
thanks for fresh look
