#economy_paver_check(container, options) ⇒ Array<Item::Materials::Alert> (protected)

Test if we are looking at a room and if so if we have economy sm control group with paver, which is not recommended because economy uses slab sensor

Parameters:

Options Hash (options):

  • :for_www (Boolean) —

    whether the check runs for the public site

  • :for_cart (Boolean) —

    whether the check runs for the cart

Returns:

#locality_check(container, options) ⇒ Array<Item::Materials::Alert> (protected)

Test if we are looking at a room and if so if we are installing in RI or NY because they require an OT sensor on the pavement ie we require SCP sm control group

  • :for_www (Boolean) —

    whether the check runs for the public site
