I have setup my home-automation-system so that it cuts the power to the brewbit at midnight, resulting in a reboot ever 24 hours. This keeps my connection pretty stable.
In addition to the not working alarms and connection losses I startet getting pretty funny graphs:
My brewbit is now able to make temperature-loops by going back in time and measuring the temperature again
I am seriously hoping that this piece of **** keeps working until the multichamper-support from BrewPi is released, otherwise I will be running into serious problems.
