I have a relatively new BrewPi Spark 3 and Raspberry Pi 3 Model B+. Up until yesterday they worked as expected as I’m learning the new system. Last night I ran
brewblox-ctl update and since that time the display on my Spark3 is very dark. Not black, just very faint as if the brightness is turned way down. And all the vibrant colors I set up are washed out now.
Separately but perhaps related, my cooling actuator doesn’t seem to be getting called any longer. The pin state is 1 but the relay is not getting the signal to come on. Could be the same for the heating actuator but I haven’t tested.
