How should I connect the Fibaro smart implant to my Faac gate controller unit? I am not an electrician and don’t want to do any mistakes. See attached image (sorry about the Swedish). Is it correct that the outputs on the smart implant are not used? They could potentially be used for knowing whether the magnetic lock (gate closed) is actived or not? So from the implant (left side): ground to ground (nr 2 in the right picture) P to nr.8 IN1 to nr.1 (IN1 on the Faac con… > [@Smart Implant of garage door and automatic gates](https://community.homey.app/t/smart-implant-of-garage-door-and-automatic-gates/29879): > > I have installed two smart implant devices to control my automatic gates and my garage door. I have connected simple magnetic reed switches to the Smart Implant inputs to set the device input alarms so I can see if the door and gates are opened or closed. The door and gates did require different parameter settings even though both operate from a short pulse on the outputs.

Right. I guess this is the easiest way and no electrician is needed. But please be aware that the FSI will also be disconnected from the power supply and will no longer work as a Z-Wave repeater. When the power is turned on again, via the Smart Plug, it should happen that it takes some time until the FSI is controllable again. If the Z-Wave mesh is generally bad, the FSI may not be able to reconnect at all. > [@Paxman](#): > > When the person is finished with whatever he/her had to do in our home I can remotely make sure the garage door is closed and the GDO is without power again. The FSI does not give the status of the garage door (open/closed) by default. The FSI only acts as a pushbutton. If you want to know if the garage door is open or closed, then you have to connect 2 additional contact sensors (reed contacts) to the FSI. But this should also be described in the linked threads. For the flows I can recommend the [IcalCalender](https://homey.app/en-us/app/no.runely.calendar/IcalCalendar/) app. Example: If the last person has left the house and there is no craftsman event in the calendar, then switch off the Smart Plug. With this app, you can also switch on the Smart Plug 15 (or 30, or whatever) minutes before the craftsman event, for example.
