I’m looking to hack/tinker my way into a dumb Intercom system i have on my rented apartment using a couple of typical wired relay tricks . . . but the smart way.
The intercom outside/downstairs isn’t so relevant, its more the handset im looking to crack into which is a
VIDEX - 3011A
My basic aim is to make it so:
1.) when the buzzer is pressed downstairs and the 3011A handset usually makes a noise (buzzes) that i can instead make that turn on a virtual switch or activate an audio message via sonos or send me a notification or turn a light on etc etc etc
2.) from the st app i want to be able to press a tile and activate a 10 second momentary closure of the door release relay on the handset… below image illustrates the only bit ive worked out, that Cables 3 & 5 Closed = DOOR RELEASE
my electrical knowledge is BASIC so i need to know a few things . . .
A.) what can i use to detect the buzz (downstairs button press) been received by the 3011A unit and turn that into a switch in smartthings, is there any sort of relay/button module available that could do this with minimal wiring that already has a device type.
B.) what device available is best for handling the low power relay required to close cables 3&5 to activate the door release downstairs (and can it be used in a momentary style with a set time period)
image below of my unit and a chart of what each cable is for . . . there is tons of plans and wiring guides and stuff on google for this unit i just dont understand many . . . if i can identify this project is possible and know what to buy i will have an electrician friend help me materialize it.
