If you want to control the element (pump) couldn't you make a button on the other workspace and have a script in the background that looks for that button to be pushed and changes the state of the pump control on the other worksheet?

I had been planning to do just that.

 

I just tried it with my boil kettle purge gas valve (BK_Gas), and put a control button "Change_BKgas" on my control box status workspace, then have the script below watching it to reflect the change.

[bloop1]
wait "Change_BKgas" State == true

if "BK_Gas" State == false
"BK_Gas" State = true
else
"BK_Gas" State = false
endif
//sleep 1000
"Change_BKgas" State = false
goto bloop1

Good idea. You should have some sleep time in there to keep the cpu from running flat out.

Do you need the sleep time in it if you are using a wait statement?  Does it work like a poll or an interrupt (clearly from my perspective it is an interrupt, but inside the guts I'm guessing it is more of a poll thing based on your comment)?  

 

I just checked my system and with that script running the CPU usage is 0.7%.

No, you don't need a sleep if there is some buffer time sitting on a wait.

Peter,

Sorry to revive an old thread, just watched the full brew day with Brian and bought the Pro version the next day.  I'd love to see an updated version of your scripts now that the one listed here is about 4 years old!

We actually did not use much of any scripts during the brew day - that was mostly a manual brew. 

That said, the script has not really changed. I’m happy to post the most recent version of my personal rig’s script, but I sincerely encourage anyone looking to automate to build their own from the beginning. Scripts are strongly linked to the Elements of a particular configuration so it can get out of context quickly unless you take the time to fully understand the elements and their hardware.

Yeah, sorry, I should have been more clear.  I'm actually writing it from a blank slate...  I've read through the docs twice even, but sometimes I like to look at how other people wrote code to go "Ahh, that's a more clever way to accomplish that!"  I appreciate you posting this!
