The recent platform instability could certainly have been a factor.
Separately, you didn’t say which model it is, but if it has a built-in surge protector, the power strip will shut itself off if there is a surge on the line. Different things can cause that, one of the classics was somebody plugging in a hairdryer to the same circuit, so it is something to be aware of.
Also make sure you haven’t overloaded the strip, as I recall, that brand has a pretty low level for surge protection. For example, a pump might be too much for it.
If you really want to investigate it, the first thing I would do is delete or disable the automation all together and then let it run for a week and see if it shuts itself off again. If it does, it’s probably either the circuit or the device or the device itself.
