@electrik Thanks, I think I can do the same with the MQTT integration (not MySensors MQTT) OSD

I'm not familiar with the project that inspired this one, but you should pay attention to hot spots, heat should be equally spread across the whole plate. plus you should have good sensors and provide controllable configuration of heat points for soldering different components according to the manufacturer's datasheet.

@nrf24_is_hard When I sent data between an Aduino and the RPi I discovered that I have to make the the receiving and the sending structs the same size AND the variables be on 4 byte boundaries. Change your char name[15] to char name[16] Another challenge is that the number of bytes of type int are different. If I remember correctly, Arduino Uno is 2 bytes and RPi is 4 bytes. To make matters worse, some compilers make the least significant byte the first byte of a word and others make it the last byte of a word. eg, sending the value 1 would be received as 16777216 (0x00000001 vs 0x01000000) There are a lot more gotcha's OSD

They are programmed with the platform that you are using, assuming it support them.

@Olaf-Jacobs It's a straight analogue read on a single ADC pin relative to Vcc and ground of the Arduino Node. In my case it's a pro-mini, the ADC pin in this example earlier defined as "Pressure", the result radioed in only if the ADC reading has changed. Three other binary inputs for contactors are polled every second on separate digital pins (one of which is pin 3), which uses all 4 pins available on this pro-mini due to the radio etc. if ((!hidro&&!Hidro&&(counter2>=132))||initialise){ int incoming=analogRead(Pressure); if (prevolume!=incoming){ prevolume=incoming; sleep(50); float tankvolume=(((incoming-102.3)*6.704199635)+0.5);//5psi sensor send(msg8.set(tankvolume,0));//This is actual volume sleep(100); }} I'm not clear on the rest of what you're trying to incorporate or what pin 3 (digital interrupt) has to do with it, the pressure sensor signal goes to an analogue pin to enable the voltage to be read.

@jvdk I agree with the point made by @evb , why would you want to wire connect the ultrasonic node rather than the usual radio connection ? You are adding levels of complexity and power demands for what reason ? My ultrasonic water tank node (pro-mini+rfm69) is now 2 years on the same 2xAA batteries sending in levels every hour (RTC), the only problem encountered - condensation forming a drip on the face of the ultrasonic head during very low temperatures.

I think these look very interesting to do with small children may be able to stimulate their curiosity, the current video games are too much influence on children, occasionally the family together to do their own small games is a new experience.

I would think that the "heavy lifting" of regulating the actual output power of the charger would be a function of the charge controller itself? Maybe you could tie into / control that somehow with your own microcontroller as brain / interface? Maybe they expose some API, serial, or other method of interfacing with their hardware? What are/were you using for charge controller? Also, what is "CT" in this context? I have read a bit here and there about solar (and related moving around and controlling of power, eg. batteries, charge controllers, etc...), as it is something I plan on doing "eventually" although I have no direct experience as of yet. So I will be following this thread with interest.

@jocke4u I run 2 RF gateways and it's not a problem. When you 'migrate' a node to a new gateway make sure to run the mysensors clear eeprom sketch first to get rid of the old routing table or you might have issues.

@GLAB No worries, was in a similar situation.. My perspective was on what the Node could be made to provide, not what could be done within Domoticz to address the requirement - eg Had heard of Dummy counters but had no experience nor understood their purpose, nor had ever used scripts. I had been sending a logical ON/OFF as well as a cumulative total from the Node and hit the same hair-pulling scenario as yourself. Now only the ON/OFF is sent and the short script makes the transposition within Domoticz to a dummy meter (I think kWhr) using the internal clock in Domoticz. Have fun

@fdlou147 According to my personal experience, I'd recommend to split up Gateway and Node funktionality and use two seperate mcu's. Wrt. to the code itself: you only set up a debouncer on one of the pins (finally: Pin 5), as you always redefine the same "flags" over and over again. Perhaps have a look at this imo excellent multi relay/button sketch by korttoma here. This one should be not to hard to adopt to your needs (still, I'd recommend two mcu's).

@Beeblebrox666 you can use them just like any other strip, with the limitation that not all leds can be controlled individually.

thanks for you reply Fumée Bleue.

@sparky60 yes, 4 inputs and 4 outputs. It should be easy to modify if you need a different amount.

@tiana I have not used it, but it is possible to create different revisions. See https://www.openhardware.io/view/4/EasyNewbie-PCB-for-MySensors#tabs-revisions as an example.

@kimot I am not handling that situation. I'm taking for granted ssr will do his job. Maybe there's some ssr safety topic I'm unaware? Suggestions for a v3.0 are welcome. About the temperature measuring... I use two sensors. The one in the board protects electronics from temperatures beyond design (60°C). It's near the ssr because the ssr's derating curve is the most limiting condition. The control sensor is placed in the bottom of the heater. It connects to the board through a 3 pin header connector.

But it's not a cube!

@sebdetours said in MDMSPanel "Nextion": Did you take a standart case that you cut out? Hi @sebdetours, yes. This is G1910 (Gainta) box. See drawing attached to projet files.

Advantage of this sensor is fast and easy installing by the non qualified personal. The sensor is designed for large agriculture facility with many greenhouses where is needed to be controlled temperature and humidity, the atmospheric pressure is for control the motor of air inlet and outlet. With help of the sensor installed outside the greenhouse provide information about positive/negative pressure inside the greenhouse. Finlay the software read accurate temp/humid value of the Si7021, and only atmospheric pressure of BMP180, the temperature sensor inside the BMP180 is used only by the sensor itself to provide accurate atmospheric pressure measurements. The sensor can be used also for home automation, and drone applications where is needed correction of the UAV barometric sensor compared to the ground barometric sensor, also humidity measurement can help the pilot to calculate more accurate flying time.

Hi! Going through examples and forum topics I've noticed that I'm using the wrong S-type and V-type. I'm writing a new version of the code with S_LIGHT and V_LIGHT so there is now dimmer functionality (which I don't need). Let's see if this helps.

@suhaila96 Hello I have not seen your question since I reviewed this topics, today. What do you mean about "setup your circuit"? How did you connected you watermark sensor and to what?

First soldered device: And a small test:

Please append support RS485

For those of you who want an extremely simple build, I've reduced it to just 5 parts: one 1-megaohm resistor (0805 SMD) one Arduino Pro Mini one Ra-01 LoRa module Male header pins Battery clips See photos.

@terxw okey, thanks for reporting back !! Let me know if there is something else. This is a 0.5v so I'm open for improvements.

@gohan said in Assistance on sensor project: While you are at it, get some extra parts too, just in case you fry something since in the beginning it is not that hard. And they're cheap.

Thanks for your fast reply. That sounds easy. And you think that the communication between sensor nodes and Gateway are still possible via wired RS485? I tried to find an example on this site for sending Information from Gateway to sensor nodes. (via SendMessage ?) For example I like to Switch on/off an light that is connected to an relay board at my sensor node. Communcation Flow: OpenHab2 --> MQTT --> Gateway --> RS485 --> Sensor Node --> Relay Board Currently I have an working RS485 Connection between my Arduino Uno's with the use from SoftwareSerial library. During my testings I realized, that the message that I triy to send "Hello" will be sent to the other arduino char by char. Is that true? Because I tried to raise up an pin on HIGH with "if(msg == "Hello")..." But it doesn't worked. Will the sendMsg method from the MySensor library handle this out of the box? Regards, Simon

@kalina, Thanks. So it will not work for my configuration. Wall switch (push button) is already installed. No possibilities to draw more electrical wires. Moreover, if i put the board near the light, i have just the Neutral and the return wire from the wall switch. No Live wire to power on the mysensors board. I think in my ase the best way is to manage everything in my garage in the electrical main board where all the wires are mapped. I can get L + N for mysensors power supply. And i can continue to reuse the original wall switch independently of the Mysensors board.

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).

I could help with that if you want to! (Eu posso ajudar com isso se vocês quiserem!)

there is no schema in this archive

@user2684 Thanks a lot

Ah.... Ok

@Søren-Heide-Larsen different networks can be achieved by setting different channels / network ID. See here for NRF24 and here for RFM69. There is no pairing function in MySensors.

No problem, I am running the nrf24 mqtt gateway on the rpi and it is working with no problem with domoticz. I choose the mqtt client gateway because I wanted to tinker around MQTT, but you could go for the ethernet gateway that is easier to manage.

Hi! I have the same problem. Did you resolve it? Thanks!

I think I found the problem. I think it misbehaved because of an illegal character in the "HOSTNAME". Changed the hostname yesterday and It was still alive this morning even if I have not pinged it.

@gohan said in Arduino Pro Mini Shield for RFM69(H)W: If I remeber right that pin is used as input so the RFM69 is not receiving any 5v signal. In addition there are people claming they have the RFM69 module working on 5v on data pins and 3.3v on vcc, but I hardly suggest to do it. thank you just what i thought . about direct 5v on data...well... i seen a big red sign saying n :DONT do it! lol Level converters are so cheap...that i ordered 5 or 10 thoguether with rfm69 board. sorry about hijack this topic, i though i was on general discussion

@nono8223 I think it will be a good idea as long as there are people actively developing & supporting the platform now and in the future. Recently the Raspberry Pi port (or Linux, in general) has been updated and included in the core library, so MySensors is no longer Arduino-only.

Hi @aramko-aramko. Unfortunately, this model is already sold. You can look at the upgraded version of this device - MDMSNode "Lighting" Rev 1.1.

@kristof-delaere The terms that you refer to are footprint/package specifications (size, shape). Here are links to the above components on digikey: CMOS SMD (oscillator) http://www.digikey.com/product-detail/en/epson/SG7050CAN-27.000000M-TJGA3/SER3999CT-ND/5175091 0207W (120 ohm resistor) http://www.digikey.com/product-detail/en/tt-electronics-welwyn/WRM0207C-120RFI/985-1466-1-ND/3648019 0207W (2.7k ohm resistor) http://www.digikey.com/product-detail/en/yageo/MCP100JR-2K7/MCP100JR-2K7-ND/2169183

@Nca78 said in Dimmable LED kitchen light (Arduino, APDS-9960, RGBWW led): Do you use a relay to control the leds or still a MOSFET ? i'm using mosfets.

Nice work! Reminds me of this great short story by Isaac Asimov from 1958.

Do you have interest to try OH2 together with MySensors Ethernet Gateway to get working? I do not have enough force to push developers to make this happen. At the moment there is some problem on this, because full control is not possible. I think that MySensors Serial Gateway is working with OH2, but I don't like to use it. I like to connect my devices into LAN not cabling via old fashioned way using serial wires.

@TheoL you are probably completely correct. I don't actually plan on building it.... it was just an interesting thought exercise.

Thanks again, learned a lot... I decide to give a try there, I also had a look on some components' datasheet and seems to be what I need... Let's see, if end up getting the boards I'll publish a review here later.

Thats perfect.. definitely have to try this.. Thanks!!

@SiLeX So it may be due to an incorrect connection? Pins of module are untagged and I connected them according to the positions of schemes that I found online. All modules have same pinout?

@hek Thanks for the comments. Sounds good. I'll report back when I have some progress.

The RFduino uses the NRF51822 which is discussed here: http://forum.mysensors.org/topic/1788/nrf51822-as-an-all-in-one

isn't it just SEXY ?

@Homer I've made a 2 double LED dimmer as well works very good and can easily be extended with more dimable leds. See my project here

Really interesting, maybe I could build something cool around the Arduino HeatpumpIR (https://github.com/ToniA/arduino-heatpumpir) library I've been building. Right now I'm integrating it with Domoticz (http://www.domoticz.com/forum/viewtopic.php?f=34&t=7179#p69647). I'm an ex-Microsoft employee from Finland (resigned about a month ago).

@joaoabs said in My Slim 2AA Battery Node: Thx! Done!

I like the project. I guess the circuit is not a clone. It costs a lot actually. Is there any other alternatives than cost < 5$ ?

@fets So far, I have only built the 5x5 board (but the others should be schematically identical). The only issue I have found so far is that I cannot get the ISP port to work. But I have checked and I have an identical setup on the 1.0 board and that worked, so I suspect the programmer is too weak to drive the net on this one. So it is not a board-issue per se, and might only be an issue on the 5x5 board as routing is the most complex on that one due to the size.

Oh, @msebbe @AWI , I have a FastLED version with a decent web API and web interface available here: http://forum.mysensors.org/topic/2705/fastled-neopixel-ws2811-node-from-arduino-code-to-web-page-with-api It's working pretty damn well Still working on my front end interface, since I'm not a designer (well, I am a 3d cad designer, not web dev). Oh, and if you knew my controller's name, you could communicate with it via TOR. Just like corporate solutions, I can communicate and control my gateway from anywhere in the world!

@lrtsenar The MySensors Libraries were designed around the nrf24l01 transceivers which have much more built in capability than a simple 433Mhz Tx/Rx pair. You can make a node which contains a nrf and 433 Rx/Tx and it can transfer messages between the MySensors architecture and common 433Mhz devices. If you are only interested in 433Mhz devices with Domoticz, see the RFLink project for more info. I believe it requires a mega to fit their libraries.

@LastSamurai good idea! Will give it a go!

thx for reply yes dragino HE works like yun I think. for linkit as the product seems new, there is a little bit less docs. but I will see, price was so interesting that it was too much tempting lol. I will tell you what I can get... for fun, I have not presented yet, but I have a board in progress for raildin : 8x relays + 8inputs for yun and I added ethernet connector+hub usb chip

Hi, sorry for the delay, I had just read your post and I could said "me too" But I solved the problem and it works for two years now. I explain my solution here, if the French don't afraid you. https://easydomoticz.com/forum/viewtopic.php?f=20&t=6497 I resume, a 7.5volts power supply, a passive injector, and a spécial home-made cable to bypass the RJ45 socket. The 7.5 v go to Vin-Gnd of the Nano to produce 5v wich is returned to the W5100. QED. Rpx.

OK, it's beginning to become clear. My initial gadgets & gizmos should arrive today, so I'll start tinkering, and I'm sure more clarity will come. Thanks for the quick responses, and for your patience. This is so far the best HA forum I've found anywhere!

@fot said: Hi! I ask my gateway about it's version (0;0;3;0;2;). It will responde with the library version number (1.4.1 in my case). It tells me that the gateway software is up and running. But it will not give me any clue about if the (NRF)network is working. That's a problem, right. I only ask the gateway if no other packages are received in $timeout seconds. /Magnus Of course ! Thank you for pushing my nose on it. Sometimes you don't see the most obvious Since my gateway is relatively close to the controller (Domoticz on a Raspi), I can do a hard reset of the gateway (via Raspi GPIO), which should resolve the issue. Cheers Josh

@Chester good point, but I was restarting the arduino and still couldn't get this to work correctly. Also, the missing "end" was just missed out of the paste here, it was in my code.

@AWI thanks for pointing me to the doc it look great ! I will give it a try

I think the something about order of initialisation was changed that fixed this problem. Try 1.4.1

Hey there @Chaotic ! This is Fay from codebender.cc Thank you for using codebender! I just wanted to let you know that one of the sketches you are using in this comment has been deleted and so it is not available for users to view it. Let me know if you have any question.

@AWI said: Can you share what is in the box? I am getting curious.. arduino_nrf24l01.rar

following this thread loosely. I have the following sensors and they seem to be accurate to some degree: http://www.aliexpress.com/item/DFRobot-Capacitive-Analog-Soil-Moisture-Sensor-3-3-5-5V-Corrosion-Resistant-with-Gravity-3-Pin/32574020064.html?spm=2114.01010208.3.2.P99ddH&ws_ab_test=searchweb201556_0,searchweb201602_1_10037_10017_507_10033_10032_10040,searchweb201603_1&btsid=8d3b5e46-a069-441a-a1f7-491ae7e317e1 and they are much easier to work with Arduino compared to Watermark stuff. Anyone agree?

Or use development branch where this dependency has been removed from the library.

@brettzky84 there is TONS of this on the Vera website, and many many folks are connecting them with a (serial I think) interface that you may buy and the plugin @Dwalt mentioned.

Any updates on how this turned out?

@destos Wow!

I built a trip wire for the post box that I'm connecting. It's however based on a mercury tilt sensor so I'm really not sure whether I think it's a great idea putting it to use (at least not with a sturdy case...). However, I can share my code: #define DIGITAL_INPUT_SENSOR 2 // The digital input you attached your motion sensor. (Only 2 and 3 generates interrupt!) #define INTERRUPT DIGITAL_INPUT_SENSOR-2 // Usually the interrupt = pin -2 (on uno/nano anyway) MyMessage msgTripped(CHILD_ID_TRIPPED, V_TRIPPED); void setup() { gw.sendSketchInfo("Postal", "1.0"); gw.present(CHILD_ID_TRIPPED, S_MOTION); pinMode(DIGITAL_INPUT_SENSOR, INPUT); // sets the motion sensor digital pin as input } void loop() { boolean tripped = digitalRead(DIGITAL_INPUT_SENSOR) == LOW; if(tripped) { gw.send(msgTripped.set("1")); // Send tripped value to gw } gw.sleep(INTERRUPT,FALLING, SLEEP_TIME); }

I compile the example sketch fine with IDE 1.5.7. Do you have uncommented the #define SOFTSPI in RF24_config.h for some reason (eg programming your gateway)?. If so comment it back again.

@BulldogLowell Yes, all is working, thanks. If you want to use this code for reference it is fully functional.

Never mind I updated to 1.4 and tweaked the code all is working fine.

Hi @tbowmo, do you mind to explain a bit about the design? I'm interested with your design. I will use these steps for removing voltage regulator, http://goo.gl/CsZaNg So the design will be battery > external step up regulator (http://goo.gl/PFt99R - to stabilize 3.3v) > vcc pin ? with these then I can use my first post design? Thanks

You should not typ "\n"! It means that you should press enter on your keyboard. On Linux I saw that I have to send "\r\n" instead of "\n". "\r\n" (Carriage return, Line feed) is the Windows return, "\n" only the Linux return.

@BulldogLowell I just realized you hyperlinked the command. Disregard my previous message.

a spark core wouldnbe the best in this case

Sorry didn't know this.

Use a latching relay. Here is one I found on Amazon. https://www.amazon.com/dp/B015MRQNXS/?coliid=I3LXTGKX4GEPUR&colid=31WWM91JAUE22&psc=1&ref_=lv_ov_lig_dp_it If you are trying to use with existing 3 ways use https://www.amazon.com/dp/B015MSYQ8Q/?coliid=I3RP8X9OMYWU97&colid=31WWM91JAUE22&psc=1&ref_=lv_ov_lig_dp_it Use an optocoupler to indicate lamp status...see the last diagram in this post. https://forum.arduino.cc/index.php?topic=435506.0

@jesse said: I found the solution on this page: http://mathertel.blogspot.com/2013/04/using-spi-bus-with-ethernet-sd-card-and.html The key is setting the Chip Select (CS) line to be different for each module.

Hi do you still have a Gateway code when using CC3000 and arduino Mega or UNO(if it fits)?

@epierre said: Both need protection (internal or external) from excessive discharge (or excessive charge, and short circuits etc) That is where our new library to check battery level goes in, we could dream to have an internal mysensor security check of a LiPo battery ! they do so in 'copters I may pass on that. I'm not used to software glitches having quite so much potential impact, and I don't need to save every gram. But to each their own!

I'll admit a newbie at this. but I"m about beyond frustrated. I've been trying to get my "Vera Edge" Serial gateway up and running. I had it working, using a nano ATmega328 w/FTDI chipset. So that was great! All your posts were very helpful! So I decided to move forward and start building my sensors. The first sensor I built was a motion sensor also using a nano ATmega328. So I got it up and running, communicating with the gateway, and than the Vera controller dropped it and I kept get the same error message, Device not ready, "LUA Startup Failure. If you all have any another ideas on what could be causing this I could sure use your help! Thanks

@legeantvert said: On the same way, i dont understand how and where are stored the values inside the gateway if not used on each reception, are they stored somewhere to be able to answer them when serial request arrive? You could bypass this on some kind of events obviously ! Actually my perl gateway is acting as the server Vera is for the arduino gateway. So from there I can trigger external URL, store data in a sqlite3 database... and so on !
