@moskovskiy82 I certainly agree, I assume your comment actually was meant to Ispandy ;-)

@ustredna , try changing this line: send(msg.set(value==HIGH)); by send(msg.set(value)); The same for msg2 line: send(msg2.set(value==HIGH)); to send(msg2.set(value)); And if you only need to update the GW on every 7 seconds (and not immediately), change the sleep: sleep( 7000 ) ; Hope it helps!

@Marco-MicrOchip-Acquadro Great. Maybe the relay example with button can help you get started. It works with MySensors 2.x.

Hello, if you're new to MySensors: you can use the light sensor example, change the calculation for your sensor, and also change the msg type to UV. https://www.mysensors.org/build/light-lm393 or use and change directly the UV example https://www.mysensors.org/build/uv According to adafruit, your calc should look something like that: UVindex = (ADC reading * Sensor_VCC / 102.4) where Sensor_VCC in your case would be 3.3V. You might need to adapt for a variable voltage as it will follow the battery voltage. In case you have trouble, post your sketch.

Thanks guys, that makes it clear for me...

@gohan Totally not updated. I did upload just now the @boots33 sketch in synch and it works. So it is my fault... But I cannot find! I re-start from fresh (err.. from boots sketch).

Cheers @gohan - I solved it in the end: First tried to set as a text sensor but changing the text on a sensor doesn't trigger an event in Domoticz (or at least I couldn't make it happen). Instead I present it as a light level sensor which can be used and is hidden away on a different tab in Domoticz....

i tried the fastled and the ChainableLED.h librarybut i'm a neewbe and it's hard for me to trabspose the examples!!

@Bogus-Exception STM32 boards are supported in the latest 2.2.0-beta, make sure to use the most recent stm32duino board defs.

I found the problem ... due to a defective sensor (light meter) the arduino could not initialize correctly. I think that is why it was calling back setup()

Sorry you are right. If you need to check "complete path" fetching time from controller is probably good way to do it.

Fortunately, 1mbps seems to work, even if 2mbps doesn't.

@Euromir The tone function will do that. I have used it in this project to register when the touch buttons are pressed. I have used a small piezo buzzer but i believe a speaker can also be used. It is very easy to use, just three parameters pinnumber,frequency,duration So to play a tone on pin 7 at 1200Hz for 60ms you would use tone(7, 1200, 60);

@dbemowsk said in MultiSensor - relays, temp, hum, PIR, gesture with various controller overrides: ... I think it is best to use compiler variables. They get rid of the needless use of variable storage space, even if the sketch is small. IMHO, program variables should be used for values that may/will change in your sketch The problem with using the #define directive for a constant is that they are not strongly typed. That is, suppose you are making a comparison, you may not realize that you are comparing a signed to unsigned number. You can see this if you compile this example with verbose on: #define LIMIT 6 const unsigned int limit = 6; void setup() { int myVar = 5; if(myVar > LIMIT){}; if(myVar > limit){}; } void loop() {} in C++, it is generally preferred to use the const keyword over a #define directive; both methods will store the "variable" in FLASH, saving SRAM as you pointed out. There is (of course) a lot of discourse on this topic (see Stack Overflow). So there are benefits to using #define. A #define at the top of a program does usually get seen by the programmer (or you, later on, after a hiatus) where they/you may not notice a regular definition on a quick glance #define sort of sticks out in the crowd. Perhaps that is why you see so much of the #define directive in Arduino programming.

@LuFi you are welcome. Hope it works out.

@sineverba if you can, check with a multimeter that the usb hub grounds the different usb ports together. If it doesn't, that could be the cause.
