@openhardware-io That looks great! - Perhaps they could make a version for the UK market called "regnsyn" ??? ;0

Hello Tilman, this is really a very nice design. I have ordered a pack of PCBs from elecrow, based on your gerber files, and have a few questions: in your BOM you have listed 5 smd-capacitors and 7 smd resistors, but on the PCB i have solderpads for 6 capacitors and 8 resistors. Can you just explain? is there a uniflächentaster-model for 2 ways? i think i have to flash the bootloader first, do you have a tutorial for this, and a sample-sketch for the board? Thank you very much

I am non technical but I have 8 wirsbo stats in my house. One of them is faulty and the unit is now obsolete. Is it possible to purchase one of these pcbs and use it to replace the one in the faulty stat ? Thanks Richard

Hi @blackchart, Unfortunately, all devices are sold out. Further production is possible only when ordering more than 10 devices (in this case, I also can modify the device to suit your needs).

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(); }

The choice of MOSFET can be tricky. Seems that irlz44n was discontinued so you may need to find one adapted to the voltage and current you want to handle. In all the cases you need to get a logic MOSFET too, meaning that they are fully open usually around 1 to 3V. Also I'm sort of confused as it seems to me that L7812CV is a Voltage regulator, not a MOSFET. So if you are actually using that in the MOSFET spot it will definitively not work. Especially if you are handling high current or voltage I would recommend using one from a reputable source for your MOSFET, I recently switched from mouser / digikey / aliexpress to mostly use http://www.arrow.com as you get free regular shipping, event if you order a couple of components (no affiliation to them whatsoever).

@yoshi824 Most of us have been where you are now! I suggest that you try to see the patterns in the code that you have working and try to make the SHT30 work from what you learn. If it does not work as you want then post here the full code you have and what it is/isn't doing and you should get some help.
