I have what may be the same issue but app shows soil moisture at zero for all five timers all the time. If I log into https://techsupport.orbitbhyve.com/#/ I can see my timers and the soil moisture appears to be updating for them. So smart watering appears to be working but app does not report accurate soil moisture. Tapping on the soil moisture in the app does allow me to make a change to soil moisture level as reported in the tech support website but app will still always show zero. They need to fix this bug.
