My occupation switch is sOccupied - it is a Switch Item. It is OFF when no-one is around.
Configuring this template and saving as a rule forces the comparison of sOccupied to true, for some reason, not ON. Is that intended? Screenshot below taken just after saving the rule for the first time, after having added the relevant Items during configuration.
(I think the description may also be wrong, but that doesn’t affect the automation at least!)
