The docs you linked to explicitly state that equal is excluded, so the automation would never have triggered for @jeff-y if what you said was the case.
Jeff, can you post your full automation & confirm that the automation is enabled?
EDIT: Got curious & created a simple automation using above:0. I can confirm it works as intended & triggers the automation when state of zone.home goes from 0 > 1.
Your automation is either disabled or something else is going on (eg. your automation is set to mode:single & is still running). Post your full automation & check the logs for errors.
