I have an assumption that your Reach RS+ may not have passed the time sync. In this case, their green LED should be blinking slowly. Most likely, it’s the reason why they’re not available in ReachView 3.
To let the devices pass the time sync, please put them near the window so they can have a clear sky view. This process usually takes not more than 2 minutes. As a result, the green LED should become solid, and the devices should become available in the app.
I see that the issue persists on 2 units simultaneously. That’s why it seems to be more like a configuration issue than a hardware-related one. But to understand it better, we need to pass through some troubleshooting steps first. Anyway, we’ll find a solution.
