It needs significant improvements and in its current version is useless
My app says it’s connected to the solar controller, but there is no input or output, Even though the system is connected to power. I've tried it with solar, shore, and vehicle power with the same results. It shows zeros in all categories except for the battery, which shows 100% regardless of the battery level. It also doesn't show the device model or version. So, in other words, the app is useless.
