I'm trying to get the hydrosys4 open source irrigation control software to work with my 16 channel relay board and raspberry pi zero w.
When the pi boots up the relay is triggered multiple times, rapidly ( this is not good, the relays will have AC loads in the final setup ).
Below shows my current wiring to the 16 channel relay board. Here's a link to a document I could find showing the relay board schematic. Sainsmart relay schematic
Is there any hardware/wiring I can add to prevent the relays from triggering during the pi boot?
