Smart Implant setup for NICE MCA2/



Hi all, 

I would like to use the Smart Implant to open a gate connected with a NICE MCA2/MC424 control. 

When opening the lid I do see the following setup:

Also, here's a screenshot of the manual:

There's already one external (Hörmann) switch connected to the terminals 9/10 and 12/15. 


From what I can see I would need to connect the implant's power to terminals 9 and 10 (red and blue cables) together with the Hörmann cables. The Hörmann cables are used with a remote in order to use one remote control for the garage door (by Hörmann) in conjunction with the gates by NICE. Generally, the Hörmann transmitter also provides a switch function. Thus, I would probably try to use them as a binary input for the smart implant. The implant's output would be connected to NICE terminals 12/15. (as an alternative, I would put the Hörmann cables and the implant's cables into the same terminal.)

Would that setup work?


Another question:

Would there be a way for the implant to check if the gate is opened or closed?


Best regards,

Q1 - yes that should work, you will get in that way possibility to open with Hörmann and via zwave only

Q2 - another one implant and reed contacts is the way to go, there is no status output (only input for opto etc sensors)

One should be able to plug into it the NICE/Fibaro module (which does have z-wave), with step-by-step and status

  • @tinman thank you very much for the input! It worked. Also I was able to add the implant as a switch into Home Assistant. I have created a button (switch) to trigger the STEP-BY-STEP button. It works OK I would say. It would be cool to have the status (gate is open/ is opening / is closed / is closing).  

    Could I use the terminals 6/7 as an input for the implant in order to check if the door is opened or closed? Would I really need a second implant to achieve this function?



    However, from the UI point-of-view I do have the following problem now:

    Since Home Assistant doesn't know whether or not the gate is closed or open the button is just a button. Is there way to use the Smart Implant in a way to have 3 buttons? One button to open, one button to stop and one button to close the gate?
