I got this board a lot time ago and finally have a little time to complete it. MCU and usb-ttl work correctly, all power suppliers are fine, board fits the enclosure. Let's move forward

Finally solved a lot of problems and checked a lot of mistakes. But now the first version of this device works almost properly :trollface:

I will make a small report in the description asap

Hi @chey, no, with the pro minis and MySensors lib I couldn't get less. Didn't measure with yet another multimeter though... My battery sensors are working now for about a year and the battery levels are between 65% and 70%. The sensor furthest from the gateway is at 65% and the 3 others at 70%. Not bad I think. https://forum.mysensors.org/topic/11499/checking-mechanical-locked-doors-by-a-battery-based-windows-door-sensor-node

@Nca78 Do you tested this board, if yes, did it work? And which CS capacitors did you use?

@bisschopsr said in BlackCircle Sensor - High "WAF" Temp/Hum. sensor: Hi All, Like the design thinking of this, although an older topic I did manage to get me one of these dishes. After taking it apart, I have one question that came to mind. Is the ventilation in the dish enough for the humity sensor? Is there any experience with that after running this sensor for a while? Thx Ralph Hello, yes I think it's enough, in fact there's much more ventilation than in many commercial sensors which only have a small hole. But it's a good test to make, I'll try to compare to a sensor out of it's enclosure to see if there's significant difference or delay.

@krisztian Hi krisztian, the singleLED board - as its name suggests - features only one LED output. If you want to have a setup with multiple LED strips you need to design a board with multiple outputs. I have already designed a board with 4 outputs, but I haven't built it. In terms of software you need to register multiple sensors in your program like this: #define numCh 4 //the number of outputs const byte ledPins[] = {9,6,5,3}; byte ledLevel[numCh]; boolean ledDimWay[numCh]; //in the setup function request the dim levels from the gateway for(byte i=0; i<numCh; i++) request(i, V_DIMMER); //in the presentation function register multiple lights for(byte i=0; i<numCh; i++) present(i, S_DIMMER); //if you receive a signal, you need to check for the sensor id setLED(message.sensor, requestedLevel); //to set the LED level (function: setLED) you need to use the sensor id to determine brightness and pin //Fade LED to set level int delta = (level - ledLevel[child]) < 0 ? -1 : 1; //Write to LED analogWrite(ledPins[child], map(ledLevel[child],0,100,0,255)); I will probably publish the whole code once I have built and tested the 4LED controller (i call it "MySensors rainbowLED") Hope I could help you ThetaDev

Just to let you know that I solved the issue. I found a library where you can control the speed and make sure it get to it's position. You can find it here: https://github.com/netlabtoolkit/VarSpeedServo I incorporated it in the Mysensor sketch and it works eventhoug it looks like it only goes like 90 degrees but it's enough for me : #include <MySensor.h> #include <SPI.h> #include <VarSpeedServo.h> // #include <Servo.h> #define SERVO_DIGITAL_OUT_PIN 3 #define SERVO_MIN 0 // Fine tune your servos min. 0-180 #define SERVO_MAX 180 // Fine tune your servos max. 0-180 #define DETACH_DELAY 900 // Tune this to let your movement finish before detaching the servo #define CHILD_ID 10 // Id of the sensor child MySensor gw; MyMessage msg(CHILD_ID, V_DIMMER); VarSpeedServo myservo; // create servo object to control a servo // a maximum of eight servo objects can be created // Servo myservo; // create servo object to control a servo // a maximum of eight servo objects can be created Sensor gw(9,10); unsigned long timeOfLastChange = 0; bool attachedServo = false; void setup() { // Attach method for incoming messages gw.begin(incomingMessage); // Send the sketch version information to the gateway and Controller gw.sendSketchInfo("Servo", "1.0"); // Register all sensors to gw (they will be created as child devices) gw.present(CHILD_ID, S_COVER); // Request last servo state at startup gw.request(CHILD_ID, V_DIMMER); } void loop() { gw.process(); if (attachedServo && millis() - timeOfLastChange > DETACH_DELAY) { myservo.detach(); attachedServo = false; } } void incomingMessage(const MyMessage &message) { myservo.attach(SERVO_DIGITAL_OUT_PIN); attachedServo = true; if (message.type==V_DIMMER) { // This could be M_ACK_VARIABLE or M_SET_VARIABLE int val = message.getInt(); myservo.write(SERVO_MAX + (SERVO_MIN-SERVO_MAX)/100 * val,255,true); // sets the servo position 0-180 // Write some debug info Serial.print("Servo changed. new state: "); Serial.println(val); } else if (message.type==V_UP) { Serial.println("Servo UP command"); myservo.write(SERVO_MIN,255,true); gw.send(msg.set(100)); } else if (message.type==V_DOWN) { Serial.println("Servo DOWN command"); myservo.write(SERVO_MAX,255,true); gw.send(msg.set(0)); } else if (message.type==V_STOP) { Serial.println("Servo STOP command"); myservo.detach(); attachedServo = false; } timeOfLastChange = millis(); }
