Hi Zac.
Can you still see if the unit is connected to WiFi when it gets in this state? I have an earlier prototype of the 4 PRO receiver and see a similar issue when I block the WiFi to it for a couple of days.

Due to the differences in hardware, this may be a red herring though, but I thought it might be worth mentioning.

Hope you get it sorted, the Weatherduino systems work very well.
