Im trying to install a DaFuRui IIC I2C TWI Shield Blue Backlight 2004 20×4 LCD Module Serial Interface on my opensprinkler pi.
i found a old repository https://github.com/stanoba/ospiLCD but it didnt work and seems to be stalled no activity.
any body done this lately with new firmware, need help.
Another option you may be interested in… I created another version of the project with a number of changes to work for what I was looking for and adapt to the new API. At it’s core, it does the same thing, it displays the status on an LCD display (remotely or on the OSPi). However, this one leverages OpenSprinkler’s MQTT notification to update the status immediately on change, rather than polling every minute. And, since the new UI doesn’t seem to support a LCD backlight setting, the script has a configurable auto-backlight setting to turn on and turn off the backlight when a status change happens. That’s a few of the differences, but if you’re interested you can check out the script and the tutorial for setup here: https://github.com/sirkus7/ospiLCD-mqtt
