Regarding your question
Are you using relays? If so, be aware that many relays boards use ‘active low’ logic, which means they will activate when the signal is low. OSPi uses ‘active high’ logic, so it will be the exact opposite.
my colleague says:
I think they we’re assuming that we weren’t using their hardware just the operating system. So that question isn’t relevant to our situation. If we were using our own hardware (relays) with their os that might have indicated the problem.
