Heated garden beds.

All monitored and controlled by MS.
Goes something like this. Glycol solution pumped through a solar collector then under my raised beds. Solar panel is charging the battery that powers the pump. Turns out pumping fluid through pipes is kind of complicated, but I got there. Have all the hardware and the beds plumbed up, just need a bit more time to put it all together.

@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.
