Another Automatic Kettle Project

Newzwaver last edited by

Hi All,

I am using the Pete B. Push button concept to turn my kettle on and start boiling and need a little help. When I press the button it will not send the code to turn the kettle on. I used the same wire diagram as Petes ground sample. It is a ground and a simple touch button as I can touch the wires tomorrow to simulate a button and confirmed it’s ground. Has anyone complete code for this and if so can I use it?
Thanks
Tim

@NotYetRated Hope you'll find good uses and a fun time while building your sensors.

@Paul-Scarbro There are multitude of solution, but since we are in MySensors Land, let's do a MySensors solution. You'll quickly see that doing that adds a lot of overhead. We'll use an Arduino Nano or RF Nano if you're going to go whole hog. It can be run from 3.3V or 5V DC, not AC. The reed switch would be connected to an input of the Nano and one of the outputs would drive a relay. The relay would drive the chime. Your C++ program would be something like: #define inputButton 2; // connect reed switch here #define outputRelay 4; // connect relay to this pin see MySensors Relay example #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 void setup() { pinmode(inputButton,INPUT); pinmode(outputRelay,OUTPUT); // put your setup code here, to run once: } void loop() { // put your main code here, to run repeatedly: if (digitalRead(inputButton) == 0) { digitalWrite(outputRelay,RELAY_ON); wait(2000); // wait 2 seconds digitalWrite(outputRelay,RELAY_OFF); // now wait for door to close while(digitalRead(inputButton) == 0) ; //does nothing until reed switch opens } } There are some subtleties that I may have glossed over, but this is the gist. By looking at the MySensors Relay example, you'll see how to integrate this into a MySensors environment. That's where you'd want to get the RF Nano. I've made the assumption you're familiar with the Arduino IDE and you've looked into the MySensors environment.

@fsgraz Did some testing Today and my RFM range is over 80 meters node to node, with no long range antenna. That will be my next test, just waiting for a shipment from China to arrive. I did how ever notice an extreme improvement when I connected the gateway through a USB hub and then started to dig through the forum. @AWI once wrote about using an external PSU to power the long range NRF PA/LAN. I'll try that this weekend as connecting it to they USB port of my PI extended the range to 20 meters Node to Node.

@OldSurferDude I use this. https://www.homedepot.com/p/Orbit-Solenoid-for-Battery-Operated-Timer-57861/203151515 Instead of having to hold the valve open, i can just pulse it. I use a simple motor controller to pulse it and when i need to close it, pulse it in "reverse". That way I could use a battery and if it only opens once or twice a day it's only a half a second or so of draw off the battery.

@Knightan I believe that your problem may be related to this block of code. See my thoughts as comments.... if (message.type == V_STATUS) { //This is true for all messages received // Change relay state state_1 = message.getBool(); //This sets state for state_1 to the received value. digitalWrite(LED_PIN_Channel_1, state_1?RELAY_1_ON:RELAY_1_OFF); // Store state in eeprom saveState(CHILD_ID_5, state_1); // Write some debug info Serial.print("Incoming change for sensor: STATE 1"); Serial.print(message.sensor); Serial.print(", New status: "); Serial.println(message.getBool()); } if (message.type == V_STATUS) { // Change relay state state_2 = message.getBool(); //This sets state for state_2 to the received value. digitalWrite(LED_PIN_Channel_2, state_2?RELAY_2_ON:RELAY_2_OFF); // Store state in eeprom saveState(CHILD_ID_6, state_2); // Write some debug info Serial.print("Incoming change for sensor: STATE 2"); Serial.print(message.sensor); Serial.print(", New status: "); Serial.println(message.getBool()); } It seems to me that state_1 = message.getBool(); AND state_2 = message.getBool(). So they both get set to the incoming value. I think you need to not set both to the same value and instead differentiate them to unique values. I could be wrong as I have not had chance to do anything related to mysensors for a long time now - I also don't use Domoticz. Have a look at the code on this page, it might help you a lot.... https://www.mysensors.org/build/relay
