|
||
|

This device can send "door open" command to intercom main unit after receiving of incoming call. It only works with coordinate line intercoms. Tested with Cyfral russian intercom.

## Parts used
|
||
* NodeMCU v3 x 1
|
||
* Double relay module x1 (or two single relay modules)
|
||
* LED x3 (or one RGB LED)
|
||
* Button x2
|
||
* Optocoupler x1
|
||
* Some resistors
|
||
|
||
Instead of NodeMCU, you can buy almost any ESP with enough count of GPIO (for example, Wemos D1 Mini). Button and LED are optional.
