Cables can come loose!

I lost a bunch of plants for lack of water.
My gardener said they were dry, but my logs showed they’d been watered on schedule.
Turned out the controller sent the signals and they got duly logged, but someone had bumped the cable and it had come partly off the controller board, breaking 3 circuits so no water flowed. Ugh.
I printed some plastic clips to hold the cable connector to the controller connector, to avoid this in future.
I see the newer versions have changed the case etc., so perhaps the problem has been designed away.
