Warning the system is not compatible with Chacon DI-O systems. I already have a Chacon DI-O system consisting of 9 sockets and two sockets brand chacon (in different rooms of my apartment) that operates on the same frequency (433.92 MHz but with 3V CR2032 battery) and remote control of this system (even though same frequency brand) is not recognized by my older devices The equipment supplied works perfectly (3 taken together and remote control) but not with the old system. Being handicapped in wheelchairs it is very important for me not having to move around with only one remote for the whole house and not with a remote control per room. it'll be useful to clarify the description that this material is not compatible chacon older generation DI-O
