I have a similar problem, except it is not brought on by sleep, it just develops over time. When I first restart the computer devices can see the sensor data from other devices, when I look again later this data has gone. In Playground all inputs are 'NaN'. When I reset the data source, the correct values are shown in the source browser on the right, and even display in the Leakshield 'old and new' setup pages, but they never seem to get passed to the main module for the device.
Running Aquasuite X.47, Windows 10 64-bit.
