Yes, the devices in the kits are the same as those sold individually. Just packaged and sold differently. Tip: Plug them all together and reset them so they all have the same key. Possible problem: Since the devices transmit data over the power line, they would have to be plugged into the same power line. Often in houses and flats, different phases of the 3-wire power supply are routed to different parts of the building or rooms. If all sockets that are to be used for data transmission can be shaded via the same fuse everything is fine. If there are different fuses, there could be problems with the data transmission. This must then be tried out on a case-by-case basis.
