Hi All,

Looking for some feedback on operating my ball valves.
They will only move a few times a day.

I know I can just call a Sub & have the main loop suspended for 10 or 15 seconds while I wait for the valve to move & the limit change, then return to the main loop.

But can I move & check them in the background?

It's not super important for the valves, but once I start adding Coms, I'd rather not have the main loop pausing every time data is exchanged between different MicroMites.

Similar code could be applied to both needs.

Thanks

Phil.

Thinking along the lines of a Subroutine that activates the appropriate relay when called, then returns to the main loop while the valves are in motion.

Probably checking the limits every 5 seconds to see they do reach their destination and also shutting the relay off after a timeout of 30 seconds.

I get the impression it might need a SETTICK Sub, but don't want to fall in the trap of calling that same sub from my main routine & getting tied up in recursive calls.

Cheers

Phil.
