I have a flow that switches on all my lights (both WEMO via IFTTT, and Insteon). It is linked to a control shortcut. Last night at 2:24 am it ran all by itself 3 times, making for a very upset wife. Two other flows also ran (an instant weather flow ran 3 times about a minute apart and a flow that turned off three of the 11 lights turned on by the original flow also ran once; both flows also had shortcuts).
Is this some April fools joke by some hacker?
