The problem has been solved for a couple of users by adding the following key-value pairs to OSPi/data/sd.json.
The file should include:
"name": "OpenSprinkler Pi", "snlen": 32probably not in that order since it is a dictionary (hash) file
The program contains code to automatically add these when the program starts. So far, it seems to fail in cases where the program has been modified by the user. I’m not sure why that is but will be looking for a cause.
