Sounds like you need some EE courses with control theory ;) Since you are
controlling a greenhouse with a considerable amount of wiring, it sounds
like your relays and A/D will be far from your main controller (BBB).

It's not 100% reliable across every cape/peripheral. Patches are
welcome to fix it, but it would best to work on something else.

Hey,
Animal brains, including those of humans, have a massively parallel
architecture.
Even though we only think at hundreds of kilometers an hour, rather than
hundreds of thousands of km/h,
due to our massively parallel architecture we can do many more simultaneous
computations than a CPU.
Thanks it worked perfectly!

Thanks for your fast reply.
I've seen it on two of our boards - out of about 15. Only one of them had
a cape (the RTC cape). Any idea if that one causes the issue?
I admit that the boards are installed over in Africa where clean AC power
sources are not common. We are putting a UPS on the

the surge when the board powers up. The idea is the PMIC

away. I have yet to

Don't forget the USB!
You can always use USB X10 controller and X10 modules and your greenhouse
electrical wiring to turn on / off devices.
That can control your high current / high voltage needs without using a
cape.
That leaves sensors feedback.
