Yes, every second and you are right. You may need one wdt_reset outside the loop too.

Not yet, I wanted to test it first. But I will soon.lnevo wrote:I meant the update...wasnt sure you updated the first post or not
I haven't had any issues with overrides with the new code. Even with the Mega-Storm, everything runs smooth with no resets.89delta wrote:Oh wow....just got home from work....added ur update last night but haven't checked the relay state yet for the skimmer.....but the mega storm option sounds wicked.....
