Holding Time - Githubissues

torrdan commented 8 years ago

Great Job...congratulation and thanks for sharing it. I did manage to install and make it running on my raspberry pi 2. I do manage to start a brewing session, but I have a problem if I want to use it during a mashing day. The time for each scheduled step does not start when the target temperature is reached, but instead start as soon as the previous phase is finished. Is it because I do something wrong with the settings or actually this feature is not implemented in the code? It would also nice to have the possibility to decide if a phase is really finished before stepping into the subsequent one. In some cases, even if the time scheduled for a phase is finished, it might be necessary to stay longer at that temperature (if for instance the iodine test is not positive before going to the mash out temperature).

Hey @torrdan,

Thanks for the kind words. I have been really neglecting this project even though I do use it myself every brew day. :) There are numerous bugs that I still have to fix in it that I never seem to get to.

That being said, the schedule code is a mess and I always wanted to find time to fix it. I wouldn't really rely on it. If you know any python it would be great to get someone looking at it. It also needs UI work and all that jazz.

Dear John,

Thanks for the very fast reply. I really think your code is a very good starting point. It just requires some improvements to make it easier to use during a brewing session. So far what I have done is a much simpler code that basically allows me to:

start and stop at any time the brewing session (need to be sure the relays stay off when I turn them off)
a display of the remaining time for each phase: once I reach the set temperature - 0.5 K, the count down starts. When the time planned for the phase is elapsed I need to push a button to go to the next phase. If I don't do that, the program will continue to keep as a set point the one of the current phase. I found this very useful because sometimes you need to stay longer than what you plan at a certain temperature
import/ modify/save mashing schedules with the duration and temperature for each phase
visualise the temperure profile on a graph
save the temperature readings on a file for post control or as a reference. All this is in python language. So the programming itself is very basic but functional. I was trying to find a way to have a better grafical interface since I am not really skilled in HTML programming. This said I will try to see if I can help in the modification of your code but I am not sure about how helpfull I can be. If it could help I can share my code with you.

My target is to have a reliable and stable system that allows me to brew in an easier way using microcontrollers like raspberry pi or beaglebone.
