Relay Node

[fwessels]

@jkandasa do this version support relays and dimmer sensors? As I also don't get my dimmer sensor to work.

[jkandasa]

@fwessels yes this version should support dimmer and relay.

[fwessels]

@jkandasa Are you using the standard sensors sketch or did you changes anything in the sketch as my relays and dimmers sensors are not working

[jkandasa]

@fwessels with standard sketch only. mycontroller will send set type message

[fwessels]

@jkandasa If I look at the Variables mapper I don't see anything for lights (relay) what Sensor type do you use for the relay?

Regards

Francois

[jkandasa]

sensor type S_BINARY and variable type V_STATUS

[fwessels]

@jkandasa I try everything and just cannot get the relay node working what can the issue be?

[jkandasa]

@fwessels can you share your node code?

[fwessels]

Hi @jkandasa here is my code

/**
 * The MySensors Arduino library handles the wireless radio link and protocol
 * between your home built sensors/actuators and HA controller of choice.
 * The sensors forms a self healing radio network with optional repeaters. Each
 * repeater and gateway builds a routing tables in EEPROM which keeps track of the
 * network topology allowing messages to be routed to nodes.

 * Example sketch for a "light switch" where you can control light or something

@fwessels I tested with MY_RADIO_NRF24 as I do not have MY_RADIO_RFM69. Everything works perfectly for me. Kindly check your radio and hardware circuits.

if you want to update sensors name by default write like this present(CHILD_ID, S_BINARY, "Relay Sensor");

[greengo]

anyone else noticed that it does not work here?

void receive(const MyMessage &message) {
// We only expect one type of message from controller. But we better check anyway.
if (message.isAck()) {
Serial.println("This is an ack from gateway");
}

server does not respond to a command (message.isAck())

it turns out that there is no certainty that my relays included.
MYCONTROLLER.ORG button in the interface does not show the correct status of the node.

[jkandasa]

@greengo

message.isAck() is all about mysensors framework. If it is ack message returns true otherwise false

[greengo]

@jkandasa
in fact of the matter is that the server does not return the values, although the sensor sends.
before, I used EasyIoT server http://iot-playground.com/download
and there it works.
