The entire web interface your referring to has been “discontinued” and is about 600 commits behind now. Furthermore, OSPi had a major, deviating, change which caused the old PHP based app to stop working with it. I honestly don’t plan on updating the PHP app because in the long term the install process is lengthy, requires additional hardware if using Arduino, and honestly no need for bulky PHP.
In order to help users I am working on supporting as much desktop platforms as possible. Furthermore, I export OSPi logs and worked with Ray to introduce logging on Arduino removing that feature from the mobile app. I also wrote a weather adjust plugin for OSPi that allows weather based rain delay as was in my PHP app.
Overall, this should be a better solution. This will also allow easy and mostly automatic updates. It’s as easy as one tap on most platforms to install and supports multiple devices with easy switching.
For the security concious I added support for HTTPS proxy with Basic AUTH. For OSPi users, a guide is available on the Wiki and hopefully this process can be streamlined in the future.
Hopefully by using the native apps you will be up and running again.
