Schema

{Laptop,Handy,Tablet} <-> WRT <-> ethernet GPIO device <-> {Keymatic, Sprechanlage}

The DING listens on *:2701/tcp for incoming connections. The protocol is ECMD with doorctl extensions.

doorctl mode set <mode>

sets the mode #Mode.

doorctl mode get

returns the currently selected #Mode.

doorctl inner door open

retracts the safety catch of the inner door.

doorctl inner door open?

checks if the inner door is currently opened. This does not mean, that the safety catch is retracted but that the door is really standing open.

doorctl outer door open

opens the outer door.

The DING has a mode register for the inner door that is always set to one of the following values:

Mode	Default	LED value	Keymatic action when entering mode	ERT effect
`locked`	X	`--RRR--`	lock door	nothing
`unlocked`		`OO-----`	unlock door	nothing
`unlocked+ert`		`-----GG`	unlock door	retract safety catch

Led colors: Red, O'range, Green

To modify modes use the #mode set or #mode get commands. Also, you can cycle through modes using the pushbutton on the DING.

These are the pinouts of the two flat cables coming from entryphone and keymatic.
