DIG end node

[computourist]

This end node is the most simple end node possible. It has a single remote controllable digital output (relay) and a button.
The button toggles the output. State changes are notified with a MQTT message.

This node is basically the DTH-node with unnecessary code removed.

I also fixed a bug in the retransmission part of the radio link. To have an idea on the quality of the transmission path I implemented system device 9, that exposes the number of retransmissions on the radio link. Minor changes in the gateway code were needed to facilitate this addition, so device 9 is only available when using gateway release 2.3.

I will release new versions of other end nodes to incorporate this fix.


New code is at: github.com/computourist/RFM69-MQTT-client

Thanks, CompuTourist for ALL your contributions.

Computourist,
I'm only seeing state changes to OPEN. There is no notification for closed. Can you take a look?
Thanks

Hi camblonie,

Code seems OK. It is working in my setup.


// DETECT INPUT CHANGE

//

curState = digitalRead(BTN); // Read button

msgBlock = ((millis() - lastBtnPress) < HOLDOFF); // hold-off time for additional button messages

if (!msgBlock &&  (curState != lastState)) { // input changed ?

delay(5);

lastBtnPress = millis(); // take timestamp

// send40 = true; // set button message flag

if (curState == LOW) {

if (toggleOnButton) { // button in toggle state ?

ACT1State = !ACT1State; // toggle output

digitalWrite(ACT1, ACT1State);

send16 = true; // send message on status change

} else

if (TIMinterval > 0 && !timerOnButton) { // button in timer state ?

timerOnButton = true; // start timer interval

ACT1State = HIGH; // switch on ACT1

digitalWrite(ACT1, ACT1State);

}}

lastState = curState;

}

As you can see in line 178, a message for device 16 is sent on every output toggle, irrespective of output state.

Maybe something wrong in your Openhab item configuration ?

You troubleshoot my system better than I can. Thanks.
