However, it is imperative to read the instructions before embarking on the configuration, because it is necessary to be very strict: I had inadvertently taken 2 associated to the same button, so I wanted to have 3 independent outlets. A reset of the unit and a total reconfiguration resolved the concern.
In addition, it is imperative to maintain a distance of at least 1 meter between each shot under penalty of misfire (plug that does not light, etc.).
Otherwise it's all good and perceived quality is really at the rendezvous.
It seems that in addition these jacks fits a range of home automation from the same manufacturer (or not!) What can be more in the future.
