I updated my raspberry pi 3b over winter and it didn’t work this spring the first time I tried to run the sprinklers. I reimagined to Buster, and it still doesn’t work. Tried raspberry pi 4 and same result. I first replaced the ospi board and transformer and it still doesn’t work. Seems like the pi isn’t communicating to ospi…. Need help.
I am pretty sure it works. There was an issue with sensors not working due to wiringPi discontinued, but that has been fixed. I am not aware of any other issue of the firmware with Rpi.
Well, if I had a RPi 3b or 4 I can test. But I don’t know anywhere to buy them. So I rely on users to report. So far I haven’t seen any report of issues.
