@Randy: this is not a limitation of the app — it’s a limitation imposed by the firmware. If you have OpenSprinkler 2.3, it actually has extra EEPROM space that isn’t fully utilized yet. To be fair, I think OpenSprinkler already provides a lot more programs than the standard sprinkler controllers you can find on the market. Most standard one give you choice of 3 to 4 programs, each with 4-6 start times. OpenSprinkler provides 14 programs, and the start times can be either 4 fixed times or defined on an interval. I am curious how complex your programs are such that you will reach the limit with only 4 stations.
