OSPi RTC not found/detected

[paddyofurniture]

I’ve recently installed an OSPi for my sprinkler system.
I would like the Raspberry Pi use the RTC but it doesn’t detect anything on the I2C probe and as a result can’t tell that there is a RTC.

I’ve followed several guides on how to setup without anything in the way of progress.

Can anyone provide assistance?

Be sure you use the settings for the rev of the RASPi board you have.

After reinstalling everything I found the RTC worked just fine until the point where I changed the hardware setting in sprinklers_pi to use the OpenSprinkler hardware.
As soon as that change is made the hwclock becomes unreachable and is no longer detected with i2cdetect.

I was only able to restore the hwclock by completely removing sprinklers_pi and rebooting.

I’ve raised it as a potential issue to the author…
