The metadata expire is on the item. It is not a rule. Look at the picture I sent earlier. Click on the item and you will see metadata.
If you want to use the hall light for more than 2 minutes then you would have to create a virtual switch and put the metadata on that and then have 2 more rules. One to turn on the hall light when the virtual switch was on and one to turn the hall light off when the virtual switch goes off.
