My Project

@FotoFieber , I use some 230V dimmable leds that I bought from IKEA in Germany about 1 year ago and and they work good. Some are Philips and some are IKEA-branded. Most important is the 'dimmable' word on them. Most of current led drivers are not designed for AC dimming, as this increase the unit costs (usually the driver is more expensive than the leds itself)...

AC works thank you for your help #include <SPI.h> #include <MySensor.h> #include <Wire.h> #include <DHT.h> #include <SimpleTimer.h> #define CHILD_ID_HUM 1 #define CHILD_ID_TEMP 2 #define CHILD_ID_MOTION 3 #define CHILD_ID_RELAY 4 #define HUMIDITY_SENSOR_DIGITAL_PIN 4 #define MOTION_SENSOR_DIGITAL_PIN 3 #define INTERRUPT MOTION_SENSOR_DIGITAL_PIN-2 // Usually the interrupt = pin -2 (on uno/nano anyway) #define RELAY 7 // Arduino Digital I/O pin number for first relay (second on pin+1 etc) #define RELAY_ON 0 // GPIO value to write to turn on attached relay #define RELAY_OFF 1 // GPIO value to write to turn off attached relay unsigned long SLEEP_TIME = 600000; // Sleep time between reads (in milliseconds) - 10mins MySensor gw; DHT dht; SimpleTimer timer; float lastTemp; float lastHum; boolean lastTripped; boolean metric = true; MyMessage msgHum(CHILD_ID_HUM, V_HUM); MyMessage msgTemp(CHILD_ID_TEMP, V_TEMP); MyMessage msg(CHILD_ID_MOTION, V_TRIPPED); void setup() { // Initialize library and add callback for incoming messages gw.begin(incomingMessage, AUTO, true); dht.setup(HUMIDITY_SENSOR_DIGITAL_PIN); // Send the Sketch Version Information to the Gateway gw.sendSketchInfo("HumTempRelayMotion", "1.0"); // REGISTER all sensors to gw (they will be created as child devices) gw.present(CHILD_ID_HUM, S_HUM); gw.present(CHILD_ID_TEMP, S_TEMP); gw.present(CHILD_ID_MOTION, S_MOTION); gw.present(CHILD_ID_RELAY, S_LIGHT); pinMode(RELAY, OUTPUT); digitalWrite(RELAY, gw.loadState(RELAY)?RELAY_OFF:RELAY_ON); //Serial.begin(9600); timer.setInterval(30000, getMeasure); metric = gw.getConfig().isMetric; } void loop() { // Alway process incoming messages whenever possible gw.process(); timer.run(); boolean tripped = digitalRead(MOTION_SENSOR_DIGITAL_PIN) == HIGH; if (tripped != lastTripped) { lastTripped = tripped; Serial.print("M: "); Serial.println(tripped); gw.send(msg.set(tripped?"1":"0")); // Send tripped value to gw } } void incomingMessage(const MyMessage &message) { // We only expect one type of message from controller.

OK, i think it work's well now: } else if (persons == 0){ if (message.getString() != 0) {gw.send(dimmerMsg.set(0), true);} else {return;} ```

@Dwalt hi my dear friend , please came on chat with me

Thanks! The boat is about 40 feet but I hope to feed all the data from the boat in one place close to the main board. I have solar panels. But they don't deliver enough power during the winter. That's why I also like to have an update of the voltage of the four 75Ah batteries so that I can charge the batteries from land (220V) when needed.

Maybe this will help you a bit http://forum.mysensors.org/topic/2106/reinventing-the-motion-controlled-outside-lamp

@Cowboy1980 Can you post your script...

I think a vibration sensor may work better in this case, and there are examples.

I have five battery powered MySensors nodes powered with CR123 lithium batteries. I set the limits at 100% at 3.0v and 0% at 1.9v. Now I just need a method for Vera to generate an alert when they drop near 0%.

Thank You for your suggestion. I will try with Energy Monitor Shield from Seeedstudio and connect it to MySensors gateway.

@ahhk said: mqtt-client-gateway Thanks Have installed the mqtt-client-gateway and works well, thanks a lot!

Maybe you van use this http://blog.gummibaer-tech.de/cul-stick-868433-im-selbstbau/ I have buildthis one also and use it in fhem (www.fhem.de)

For anyone whois interested in how I mounted the electronics into the lamp. I posted an article about this on my blog http://www.houtbewerken-voor-dummies.com/grenzen-verleggen-een-moodlight/ it's in Dutch but you can translate this with google translator.

Hi These sensors are really quite neat. I got quite accurate measurements from 4,9 to 44 litres/min, I couldn't go any higher, the output fed into the audio input on the PC with a simple and free frequency meter software. Amazing for a few dollars. The downturn is the pressure loss across the meter, 0.08 bars at 15 L/min rising to 0,69 bars at 41.8 L/min : Here are what I measured dP L/min flowmeter 15 0,08 18,4 0,04 24,7 0,21 26,5 0,24 30,7 0,29 34,2 0,4 37,3 0,51 40,0 0,63 41,8 0,72 42,5 0,69

Hi, this one looks very nice and not shouting "i am a sensor". I am just curious, how long do the batteries last?
