I ran into serious issues after updating firmware to the latest version on my ospi. I use one extension board, S1 to S16.
I have a pump on s1. Once i turn on any Station manually, S1 and the Sx cycle between 24v and 0v every second.
I tried to set the masterstation to S11 which I am not using, same result. Using two stations as masterstation and setting Sx to use both again shows same result. Powersupply of ospi is at a stable 24vac.
I also noticed that the off voltage readings of stations 1 to 11 are 0.5v which seem ok, but station 12 upwards read 6.5v in off mode. These stations are set to disabled.
