I build a Opensprinkler 3.2 version with dc board, and before start i think that i read that is not necessary to connect opensprinkler to a remote acess point and could run in acess point mode, it is true?
In my project, i don’t have acess point nearby, so this is a requirement.
OpenSprinkler does not require an access point to run — in fact, initially itself is an access point, allowing your phone or laptop to connect to it to set configurations. If you plan to use it in access point mode, just make sure to use the opensprinkler mobile app, and the device’s ip address is 192.168.4.1. Almost all functions will work in ap mode, except (for obvious reasons) any internet-dependent features like weather-based adjustment and NTP time sync (you can set device time manually).
We used to support browser apps (like Chrome apps) in the past, but over time such support has been dropped (for example, in recent news Google is discontinuing Chrome apps)
