Local heating override.
-
Hi,
I need some help.
I have a Node controlling my floorheating, but now I want to make a "local" override button, incl diode indicating lights.
My idea is to build it all in a clear plastic housing (so I can see the relay lights). I then thounght about using a tactile button as "override" and some 3mm leds as indicators. Green = Auto, Red = "Manuel" and Blue = Overridden.
This Is my working scetch on a Nano.
/** * 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. * * Created by Henrik Ekblad <henrik.ekblad@mysensors.org> * Copyright (C) 2013-2015 Sensnology AB * Full contributor list: https://github.com/mysensors/Arduino/graphs/contributors * * Documentation: http://www.mysensors.org * Support Forum: http://forum.mysensors.org * * This program is free software; you can redistribute it and/or * modify it under the terms of the GNU General Public License * version 2 as published by the Free Software Foundation. * ******************************* * * REVISION HISTORY * Version 1.0 - Henrik Ekblad * * DESCRIPTION * Example sketch showing how to control physical relays. * This example will remember relay state after power failure. * http://www.mysensors.org/build/relay */ #include <MySigningNone.h> #include <MyTransportNRF24.h> #include <MyTransportRFM69.h> #include <MyHwATMega328.h> #include <MySensor.h> #include <SPI.h> // NRFRF24L01 radio driver (set low transmit power by default) MyTransportNRF24 radio(RF24_CE_PIN, RF24_CS_PIN, RF24_PA_LEVEL_GW); //MyTransportRFM69 radio; // Message signing driver (none default) //MySigningNone signer; // Select AtMega328 hardware profile MyHwATMega328 hw; // Construct MySensors library #define NUMBER_OF_RELAYS 8 const int RELAY[] = {A0, A1, A2, A3, A4, 6, 7, 8}; #define RELAY_ON 1 // GPIO value to write to turn on attached relay #define RELAY_OFF 0 // GPIO value to write to turn off attached relay MySensor gw(radio, hw); void setup() { // Initialize library and add callback for incoming messages gw.begin(incomingMessage, 12, true, 0); // Send the sketch version information to the gateway and Controller gw.sendSketchInfo("Relay", "1.0"); // Fetch relay status for (int sensor=1, pin=0; sensor<=NUMBER_OF_RELAYS;sensor++, pin++) { // Register all sensors to gw (they will be created as child devices) gw.present(sensor, S_LIGHT); // Then set relay pins in output mode pinMode(RELAY[pin], OUTPUT); // Set relay to last known state (using eeprom storage) digitalWrite(RELAY[pin], gw.loadState(sensor)?RELAY_ON:RELAY_OFF); } } void loop() { // Alway process incoming messages whenever possible gw.process(); } void incomingMessage(const MyMessage &message) { // We only expect one type of message from controller.

I need to put in 3 LEDS and a button somewhere. Any help would be appriciated.
