Hello,
I am looking for some guidance for a contact closure relay with feedback. I need to add a relay to something in my home that I can connect into my home automation system. I need it to be able to communicate back to my system saying it is either open or closed. I have not seen a relay that can do this operation, so is there a addon circuitry that I can add that gives me this feature.

Thank you,
JR

Hello,
Thank you for the reply. I do understand DPST or DPDT, but so I understand how would that feedback to my controller showing in what state of the relay.

Thank you

How did you want to communicate?
Bluetooth? Hardwired? serial?

Hello,
I would prefer hardwire, RJ45. But at this point, not to picky.

Thank you

Pretty standard interposing relay arrangement.
Drive the coil from whatever in the system to be monitored, then the dry /voltage free contacts feed back the closure of the relay to the monitoring equipment.
Could also be any number of other alternatives such as opto isolator.
