Hi, just filling in for Rhoda - the fix we deployed should correct the first case you mentioned in your last comment, as the fix specifically addressed situations where Sense was being knocked off WiFi and sometimes never coming back online. Are you still seeing gaps in your historical data?
In the second case, this can still happen if Wi-Fi signal is too low or is going in and out enough so that the average transfer rate falls below 2k/s sustained over the whole day, or more realistically ~20kb/s for when Wi-Fi is connected if it is going in and out. If the transfer rate is not high enough the buffer will not be drained fast enough and that can cause gaps. Given the low rates we are not seeing this problem very often, but please let me know if you are still seeing issues and we can have someone to look into it. Thanks!
