~12 months ago I managed to knock my open sprinkler off the bench which damaged the screen. The unit has been working perfectly fine since, but I was hoping to replace the screen and don’t know where to get one from.
I tried unplugging the screen and putting it back in again. It didn’t help.
Echo @tigercjn: you can find SSD1306 IIC (also called I2C) OLED screens on Aliexpress for a few dollars shipping included. Make sure it’s 4 pins (the non-IIC type has 6 or more pins which wouldn’t fit OpenSprinkler 3.0).
