License documentation required by CERN is missing. Please upload the necessary documentation. See instructions on the forum on open source hardware licensing.

@Anticimex , I may have chosen the wrong option, please specify which license I need for open use and do not need to upload files?

@YuryPol as far as I know, all licenses require some form of documentation. In all cases I know of, this is documented with the license or on the licenses official site.

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(); }

I'm thinking of 4 PIR sensors (at each end of the two aisles). And I was thinking of a reed switch at the top of the garage door opening, and one at the door into the house. And the most convenient location for the relays controlling the lights is still a 7th location. I could put 7 wireless nodes into the garage, but then I have to run power to all of them - if 5v we still have the same long wire issues, if 120VAC then I need 7 power supplies. And the local control now involves passing messages between nodes rather than just sensing input pins and controlling output pins on the same uC. The cables supply power to the RF enabled nodes will have the same length (whether DC or AC power) as the cables going to a simple sensor, and follow the same routes. So it would be possible to do that, but at considerable cost in money and time and complexity - compared to just running a three or 4 wire cable from the main node to a $2 PIR located 1o-20 feet away, if that can easily be made to work (perhaps with the addition of a couple of small, cheap passive components. I don't know if I do need to worry about inductance, capacitance, reflections etc - that's why I'm asking. These things aren't usually specified one way or the other - you kind of need some practical experience. If those are indeed killers that cannot be fixed with a couple of passives, then I may go to the "make every sensor a full node with AC power supply and distribute AC to them instead" route. But wouldn't it be nice if I can do a $2 easy fix instead? One data point - in the Do It Yourself Christamas lighting control community, they routinely get away with sending TTL or CMOS signals quite a ways from a control unit to an optoisolator input (which controls a Triac to form a SSR which does PWM dimming of an AC circuit). The signals are just a 120 Hz PWM signal but the edge timing is at 120Hz * 256 PWM divisions. You won't find much about driving a 50' cable from a TTL or CMOS output in the datasheets, but it works in this application! It would not work if you were sending a 1 Mbps signal tho. So I have some hope that a PIR 20 feet down a cable may be able to pass back a quite usable logic signal, since it changes rather rarely. But I was hoping for some advice about the gotchas. Remember the sensors I've mentioned are magnetic reed switches, LDRs, and PIR sensors - only the latter needs power per se separate from the signal.

@yoonie said: For the pro mini version, should i create another Openhardware project, or should i put it here, in the already existing project? Might be better to create a new project as they uses a different set of design files.

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.
