That reminds me - I get this happening as well: As seen in the *.wsp files and in this order:
CPU
Mem
Uptime - note the uptime is not zero - it’s days.
Note this has all worked in the past and seemed to act differently on an openLuup restart. Note thay I have not restarted openLuup in days, so as not to unsettle the scene timing issue. As you can see the two minute timer is working but what is the stuff in between?
