Bridge extender/repeater

Ok, mailbox in front of house, smart floodlight on shed in rear of house, solar patio light and outdoor outlet all in between. 300ft from mailbox sensor to shed floodlight. Wood siding and framed home in middle of 300ft. Always get a poor bridge connection to mailbox sensor and poor connection to shed. Moved bridge to 6 different locations, would go offline moving either direction on mailbox or shed light. I would think the RF of bridge is better than this. You offer a wifi extender, but NO bridge/smart light extender/repeater. Zwave is supposed to mesh, but you do not clarify which devices act as mesh node.
