Brewpi stuck waiting to cool


#1

Started a new brew. Set the Brewpi to “Beer constant” at C. The GUI is not collecting data and the LCD display sits at, “waiting to cool.” How can I fix this?


#2

Sounds like you are using the Arduino version. It has a hard coded minimum OFF time and a minimum time for switching between heating and cooling. Once this minimum time has passed, it should start cooling.


#3

What is that minimum time? The LCD display has read, “wait to cool 00m03” for more than a day. It’s not plotting data either.


#4

That sounds like there is no connection with the Arduino. I thought you meant an actual hardware display.

Try rebooting the Pi and power cycling the Arduino.
Also check for any error messages in the log files.


#5

Sorry for the confusion. Not a physical display, but the “LCD screen” on the web interface. I reset the power (unplugged the entire unit, then plugged it back in) and that didn’t help. I booted up just the Pi, then the Arduino, and it is not working properly. Obviously there’s an order of operations that I didn’t fully appreciate.

Problem solved. Thank you so much for the great product and help!
