I still have issues with valves that don’t work.
I can’t tell when it happens, just random. Not after a power cycle or something. I leave the system powered up at all time. I leave it one day all valves working, another day after I come back and a few valves don’t work.
After one of the last updates the LEDs on the valve control board behave different. Result is that if the valve is in open or closed position, both LED’s are on (opened/opening or closed/closing). The LEDs of the malfunctioning valve control board behave different, even though the valve is completely opened or closed. Only the opened or closed LED is on. The opening or closing LED is not on, my guess is those are controlled from the sprak.
If I look in the valve control board widget of the malfunctioning valve contorl baord the connection is still good, at least that is what the spark thinks. It looks like the connection with the chip on the vavle control board freezes or something…
From breblox a command is sent to the valve control board. I checked in the developers mode (ctrl+shift+I in chrome).
A powercycle at the 5V to the control boards is the remedy.
Is there already a solution for this problem?
In the mean time it would be great to have the actual feedback of the valves in brewblox. At least then I can see if all the valves are in the correct position… I already pumped half a batch into the drain because of a malfunctioning valve
