Is it possible to control the OSPi v1.2 with just an Arduino?
I found the Raspberry Pi + Wifi connectivity unreliable and have good experience with Arduino + RF modules. So instead of buying a new Arduino based OpenSprinkler I would like to “convert” my OPSi to control it with an Arduino.
It’s possible but will be a lot of work. The OSPi schematic is all available in Github. But before you start, have you tried to use wired Ethernet with RPi, which is generally more reliable than WiFi?
Running an ethernet cable through my garden is the thing I was trying to avoid with the OSPi.
It’s not just the WiFi, my experience is that the RPi platform ins’t very reliable and thus not suitable for these use cases.
Instead of a lot of work I think I will replace the OSPi with a multi-channel RF control switch and pair it with my current openHAB setup.
