  Thank you! I use phonechargers from renowned manufacturers. I'm nog so concerned for my 5v nodes. Planning tot rebuild them with 3.3v micro's on batteries. Now orientating on 230v switches. The relay actuator build on this site doesn't feel safe. I read relays produce heat. I'm searching for a consumer product to safely tinkering with. No 3rd party clouds, etc. Hoping someone over here has experience with the sonoff or comparable products. Tips welcome!

  @Alexander-Ivanov The nrf doesn't provide a good way to get signal level. Some more info in https://forum.mysensors.org/topic/1022/nrf24l01-signal-strength-request The best approximation is to use the PingPong example.

  @sundberg84 said in Synchronizing actions between nodes: @LastSamurai - are you using the webgui to switch? I think its rather quick using a motion detector -> light/relay. Using the gui though takes 2-3 sec. I am using both, the web ui, and a motion detector node + a rule setup in domoticz using dzVents. For the motion sensor its hard to tell how fast the reaction is though, because I don't know the exact range of it. Perhaps I'll try with a button node next, just for testing purposes. PS and the ui isn't that slow. Sometimes it takes a little longer but mostly just ~half a second.

  @meanmrgreen You should use non-blocking code with millis() and if{}. Look e.g. at https://forum.mysensors.org/topic/461/motion-sensor https://forum.mysensors.org/topic/2717/repeater-node-with-sensor/12

  I would probably consider some extra esd protection on the input of your arduino board. Like a series resistor and a couple of esd protection diodes Just to be on the safe side

  @tekka Found it! I added a #ifndef so I do not have to change it every time I program a node (and forget at what setting it is the next time....).

  Of course you could use rpi as gateway, but as personal advice I'd suggest to get some mini pro as sensor nodes and keep the Uno as the gateway or the prototype platform. The most flexible solution would be to make an mqtt ethernet gateway and use rpi as mqtt broker and controller with openhab or whatever else you like, since the mqtt in the middle allows also to have multiple controllers. I also wanted to try openhab and tried openhabian but it turned out to be too complicated, so I moved to domoticz and it was much easier to put things together.

  I found problem in my code: my node sends update if only it has value changed, which can take really long. @flopp, "it will start to search for a Parent after 6 failures" - does 6 tries happen automatically or the node need to send something 6 times?

  What I mean is if you have products using 433MHz or 868MHz already, using MySensors gateways with radios using those frequencies will not work, because those devices are not using MySensors protocol. If that's clear for you, then you're fine

  Thanks for the reply, @hek. Maybe here we can take things one at a time. For a first step, would building the GWs as MQTT allow connections through a broker such that multiple GWs will work? "Arduino compiler" is bad shortcut name. I meant that there is some transformation arduino does to the code before it reaches the gcc compiler. This is what i want to avoid and have my code work with gcc directly, even if using arduino core/libraries.

  Hi @TheoL how is life and hacking? I got reminded on this topic when I saw that Domoticz now officially supports the MySensors MQTT Gateway So I was thinking maybe you have some time and material to contribute to the subject, I see there is a lot of people (me first) not really understanding how they could benefit from MQTT protocol. Since you mentioned the presentation/tutorial last time Cheers!

  Hi, it is some time since I made this (and used it to be honest) but you can check this post where I integrated what you are asking about. https://forum.mysensors.org/topic/4552/sleeping-while-waiting-for-double-click-delayed-sleep/3 Node and the code is unfortunately not in use currently so I do not recall all the details, but maybe you can get something out of it

  There is no pairing. You could use deterrent channels or (if security matters) indeed have a look at signing.

  Hmmm.... I guess this topic is kind of dead. I tried to desolder the transiver but failed miserably (to much heat in frustration over that the thing would not come loose). So the PCB lost 2 solderpads. This means I cant go on with this hardware. I might toss the Arduino aswell, its solderd on all pins. Well well... I now have a different problem. I now have a Arduino Uno, NRF24L01 and a 1-wire sensor. The new Node seems to be running as it should but it doesnt get any respons from the gateway. The Gateway is talking to my old Node with 3 sensors. A thing that is a bit wierd is that i Updated the GW to version 2.1.0. I thought that I would loose connection with my old Node that I belive is version 1.6 but those are running fine together. The new node is the same version as the gateway. This should probably be a seperate Topic but I feel bad for starting multiple topics so close together.

  @antlomb My personal opinion: when inititial euforia about ESP8266 has ended, people started to realize that the chip is actually not that reliable for solid tasks like home automation. Besides, it has huge problems with deep sleep and even if they are fixed, the module reboots on every wake-up consuming a lot on start up

  Thanks guys ! Since i am using Domoticz, i'll stick to unique ID's overall.. That would mean that you cannot use the "auto" setting for ID's if you are using multiple mysensors gateways with Domoticz at all..

  wdt.h is included on Arduino IDE. This example show how it's work: #include <avr/wdt.h> int counter=0; void setup(){ wdt_disable(); Serial.begin(9600); Serial.println("Starting..."); delay(1000); wdt_enable(WDTO_8S); } void loop(){ wdt_reset(); Serial.println(counter); counter++; if(counter==5){ while(true){} } delay(500); }```

  No one? First. I don't have any radio interface... Second, micro pro isn't supported So, When I don't have any radio sensors I just want to send local attached sensor data to the controller. Can I configure the library to just send my data? Or can someone describe how much communication are made with the controller. Are there any more messages rather the presentation and actual data that need to be sent? Any "handshake"?

  @zsakul Try downloading the latest version from github. The master branch will be updated to version 2.1 very soon and I recommend waiting for that. https://github.com/mysensors/MySensors/tree/master Once you have updated you should be able to use MY_TRANSPORT_WAIT_READY_MS in your code. I have it working in my device. You could change MY_TRANSPORT_WAIT_READY_MS in the myconfig.h file but if you do it there every node you build will have this setting (which my not be desired).

  Yes, WAN I mean over the internet, because in my "final vision" I want to have conectend more GWs from different buildings to the same controller. So is GW<->controller comunication somehow secured? Or is better to use MQTT? Or there should be always a VPN connection for sure in safety? It is possible to connect multiple Domoticz instances, see https://www.domoticz.com/wiki/Setting_up_Device_sharing I have not tried it and I don't know how secure it it but it might be a good solution, but requires a Raspberry Pi or similar in each location. Mqtt gateway with TLS and username+password could be a good solution. VPN or ssh tunnel should work but will require extra hardware (support in router or a raspberry pi in each location). I have one more question - in manual how to make a ethernet GW is an option to choose W5100 or ENC28J60 module. Is there any significant reason why to choose W5100 when its price is almost 2x higher than ENC? Yes. If you value your time at more than 50 cents per hour The enc28j seems to be much less stable.

  That's a tough one. There are LED replacement fixtures, but to cover the same area you'd need a very expensive one. MH lamps should not bust easily, so you have to make sure the lamp and the ballast are a match. If the ballast is for a bigger lamp, yours gets an ass whooping every time it starts, dramatically diminishing it's life. For large areas, MH will provide the most efficient way to light the lot up. But make sure the fixture and lamp are a perfect match. There are LED replacements, but those units cost an arm and a leg. Cheaper China alternatives will be more expensive in the long run, because they don't run efficient, and fry a lot because of poor thermal design. My 2¢: get a replacement MH lamp. Maybe adjust your lighting schedule a little to keep the lamps to live longer; less starts per day, and keep lighting hours to a minimum. Good luck!

  @CRF interesting. Domoticz seems to have removed support for the image. This old page had information https://www.domoticz.com/wiki/index.php?title=Domoticz_RaspberryPi_SD_Image&oldid=216&diff=prev I guess installing by running sudo curl -L install.domoticz.com | bash is the way to go nowadays.

  @Redguy from http://m.electronicdesign.com/what-s-difference-between/what-s-difference-between-rs-232-and-rs-485-serial-interfaces: "A logic 1 is a level greater than –200 mV, and a logic 0 is a level greater than +200 mV. Typical line voltage levels from the line drivers are a minimum of ±1.5 V to a maximum of about ±6 V. " So you should be able to mix them as much as you like.

  @hek said: It takes a few failed transmission before it tries to "find new parent". Not sure what happended here without seeing the node log. @mfalkvidd said: @รอเรือ which version are you using? 2.0 has a problem with nodes that go back to sleep too soon after a failed send. This is fixed in the development version. See https://github.com/mysensors/MySensors/pull/558 for details. Thanks guys! Well, I'm on 2.0.0. I'm not the "adventurous type" so I'm not on the development version if You get my point (ha ha). It's good to know that there exists some healing mechanisms in the communication. I might wait for the next stable release or I might build me a dedicated "MySensor : RepeaterNode" with an external antenna to facilitate the communication with my upcoming battery powered nodes in my garden and for the lawn mower that really must be automated soon.

  @Cliff-Karlsson Assuming your PSU is only driving your buck converter, then, if the device data can be believed (a big IF by the way), then yes, I would expect it could deliver 12a at 5v. That said, you're buying a cat in a bag, and from a no-name Chinese manufacturer no less. So, for instance, who knows whether the parts are actually rated for what they proclaim themselves to be. Those are electrolytic caps. Usually, they don't do well when exposed to heat, and in that design they look to be quite close to the heat sinks. Are the caps really rated for whatever heat you might encounter? That's a big unknown with these types of cheap boards. On the other hand, it's only $4, so maybe that's a trade-off you're willing to live with.

  @andrew Hello Andrew, as Anticimex already answered also other IDE's are possible (Atmel Studio with a arduino plugin seems to work) Atom, and others I use the Eclipse + plugin solution and are happy with it. It is really a powerfull solution with many configuration options. I had a few discussions with the maintainer of sloeber (Jantje) and in general i made a few observations that summerize yours: lsee discussions on github The problem for cpp is that you have to declare the prototypes because you lose the confort from the ino suffix.

  @pellusfromtellus - well yes and no. I live in Sweden, we had aprox 1600 stove fires (dry cocking and electrical failures) last year and 15 fires from usb chargers... (no ref, heard on tv). So you need to be carefull but also know that its not impossible and you will not start a fire if you have a basic knowledge. Its finding a good balance...

  @Michael_K , If we go from the front to the back this is what is needed: 1 Node: For example a door bell. This node sends information to a gateway. 2 The gateway takes the message from the node and sends this to a controller. For instance Openhab or Domotics. This can be done in several ways. MqTT being one. 3 Controller: takes the information and displays it to you. So in my case, I hardcode Node ID and CHILD ID (the complete door bell is a NODE whereas CHILD IDs may be the button pressed and maybe temperature reading at the same time). This sends to Gate way that takes the information and creates a MqTT message. What this message is, please read the instructions on this site.

  @greavette great idea. You can do one sensor to monitor the water in the boat, one to operate the bilge pump and one to monitor the battery. I also think it's great that you are getting the kids involved. If you need help, there is a great community here that can help with almost anything.

  I thought I'd report back with my code. The sensor is up and running. I don't like that I just had to present switches but I'm not skilled enough to use the "custom" field and make a control in Vera. (On/Off, Blue, Red, Green, Motion) So this will have to do for now. It's probably OK as I'm just going to use automation to actuate the switches. /** * The MySensors Arduino library handles the wireless radio link and protocol * between your home built sensors/actuators and HA controller of choice. * The sensors forms a self healing radio network with optional repeaters.

  +1 for RFM(433Mhz) I´m already running NRF and keeping it (have build many nodes on it). But, for example I have a garage (steel structure with sheet-metal paneling) and its ca.6 meters from NRF gateway - no signal! Same distance RFlink (433Mhz) works just fine.

  @Cliff-Karlsson - from my point of view (Domoticz) it wouldnt be hard at all. You need one lux sensor and a dimmer. The code could be written in Lua for example and executed every time the lux sensor gets a new reading.

  @qwertz1 Heartbeat support: the sensor can send a "heartbeat" message to the controller to let it know it's alive. The heartbeat message does not update values. Not all controllers can interpret the message. Ack: when you enable ack in a message the receiving node "acknowledges" the message by returning it. It is a way to make sure that the message arrived at it's destination. Some controllers can resend and/or report. This is used mostly for actuators (lights/ motors) to be it is switched on/off. OTA (over the air) means you can update the firmware (sketch) on the MySensors node without wiring it to the computer. Request: the controller supports "requesting" values. i.e. a node/sensor can request a last known value from the controller (or other node). Typical usage is to request a last know switch state from the controller after a node/ sensor powers up. Another usage ( at least for me) is requesting all kinds of information from the controller for remote display (V_TEXT). I hope it clears the sky for you..

  The sensors on the I2C buss has an address. As long as there is no address conflict on the buss you can add multiple sensors. You need to check what address your sensors are using and/or the possibility to change the address of your sensor if you find that there might be a conflict.

  @Michel---It Thanks for posting the image. Anything you find on the forum that mentions esp8266 or nodemcu will most likely work with that node, including https://www.mysensors.org/build/esp8266_gateway which is probably the best place to start. There are also several threads on how to connect local sensors to the esp8266. I would give you some pointers but I am on a train with crappy Internet.

  @sundberg84 said: Im using DomoFence for geofencing and webgui for other. Couldnt get the other app to work with geofence I do have the geofencing in the Domoticz app somewhat working. My test scenario was to have a script that would close my garage door once I left the fence area. The problem I ran into was that when I would come home, it wouldn't register right away that I was inside the fence area, so when I would open my garage door, it would think I was outside the fence area and shut it right away. I think that might be an issue with the phone and not Domoticz.

  @Sean-Brockest said: not sure what a node or controller is. I don't care how it works, really. A node would be a MySensors device (arduino with a radio module) with one or more of the following attached; sensor, relay, switch, or something like that. The radio module would talk to a gateway node that is attached to a computer running some kind of controller (Home Automation) software. If this one thing is all you are trying to do and you are not trying to set up other home automation stuff, you shouldn't need the whole MySensors setup. You could probably do this with just an arduino board, 2 DS18B20 temp sensors and a relay module. The only problem in that would be that you would have to program it for a certain temp differential and any hysteresis that you would want in play, and it would be static until you re-programmed the arduino with new values. There would be ways to set it up to be programmed as far as the set temps and the switching, but that would take a lot more hardware such as an LCD screen and some switches for programming. It would also make the arduino code quite a bit more complex.

  @sundberg84 As far as I understand by looking at the code you have sensor on the same node which is requesting the pulse count from the GW?? OR you have reed switch on this node and sensor is on some other node? In the debug prints do you see a READ message in the serial monitor for your node which has reed switch? With me, I am sending the request() from node 1 to node 2. I can see SEND message in serial monitor of node 1 and READ message in the serial monitor of GW and also a SEND message in GW serial monitor and READ message in node 2. So the message is reaching node 2 successfully but my node 2 is not sending any reply to that message. So, node 1 is sending to GW, GW is receiving it and sending it to node 2, node 2 is receiving the message but node 2 is not replying. Is this what is supposed to happen? OR node 2 is actually supposed to send a reply back to node 1?

  @Spanners what hek means, the channel ID is set compile time. So before uploading to your node. So putting it in before() is currently not an option. What you can do is putting the RF_BASE_RADIO_ID define in a separated include file (.h) and include this file before the other defines in all the sketches. So you only have to update the ID once for all your sketches.

  @AWI Thanks for the piece of code. Now i can see where i was wrong! Let me run it... this seems to be missing the interrupt part though. I will try using DV on Int2...

  @marex after sleeping I think I understand your question. Start by writing nothing in the setup, presentation and loop. Just use the examples as they are, following the instructions on the links I have already posted. That will get you a working gateway and working temperature nodes. You can then add your own code for handling communication with your phone, or just use one of the available controllers which will handle that communication as well. With MySensors it really is that simple. Note: I am moving this discussion to a separate thread, since it really has nothing to do with the MySensors 2.0 release.

  Hi @aishwarya7 Welcome to the MySensors community! I am not familar with the attiny13, but from the datasheet it looks like it has too little flash and sram to run MySensors. Instructions on how to upload sketches to an Arduino is available at https://www.mysensors.org/about/arduino#uploading-example-sketches See the buying guide for information on which components are recommended when getting started.

  They do look nice, but it seems that they have a standardized icon / layout, that can't be changed. I would like to have the possibility to display arbitrary information on my dashboard / scene controller, so I'm creating a webpage mimicking a "weatherstation type display", and plan on using a cheap wall mounted tablet for the interface. this will also make any updates to functionality on the scene controller easy, as it's just a website that needs updating. preliminary proof of concept is at https://juletraesfoden.dk/t2/app. Backend is a mix of domoticz / node-red / python webservices..

  I am using my RGBW controller like that. I have some of these nodes controlling multiple strips. Although if you want to controll them individually you need a controller for each one. (or build one that has more mosfets, then you are only limited by the number of pwm pins on the arduino you are using).

Tnx for the answer anyway i will try the higher speed setting (57K6 or so) Btw good write up about the RS485 setup on the home page it will defenetly speed up things (as i spend a few hours wit wrong setup) Regards, Stefan.

  @vizonyc You need to build a Network Gateway. follow the guide and it will be easy. I used a UNO with a network Shield (Thera are nice shells for that on thingiverse, like the one I built ) When that is build you use the GatewayW5100MQTTClient sketch. Just edit your mosquitto server in the sketch and upload it to the gateway. Thats it

  Thank you very much. I did all that and the GW seems happy except for the fact Vera doesn't see the gateway. I get this from my vera. Vera (MySensors plugin : Choose the Serial Port MySensors Plugin[12] : Running Lua Startup I remember having to go in a change the baud rate on the USB port in Vera but I haven't been able to find that again. I've read where nothing has changed in how the gateway talks to Vera. I was running a Nano as my serial gateway. but I saved it just in case and I'm now using a Uno. Vera firmware rev is 1.7.2043. I've also read you can't use a serial gateway with UI7 but my Nano has run fine for 8 months or so. Also is there a writeup of what the Inclusion button does besides return a 1 then 60 sec later a 0. Should this put the Vera in Inclusion Mode? I cleared the eeprom of the Uno.

  @TheoL My Domoticz works again, I have to give it a fix ip because the IP was change and for your info, Your solution worked very well. It is now visible in Domoticz. Thanks for the support now I have to wait for other parts, I wait for my last parts for this project, an IR receiver so I can use a remote controle. After that I can use this project as a universal project, a default design in basic. Again thanks!

  @Tris I think this would work: present(sensor + MAX_ATTACHED_DS18B2 + NUMBER_OF_SWITCHES, S_LIGHT);

  @jpbabou if the node stops sending, it probably has a power issue. Using more power will make the problem worse. And changing the power level on the gateway when the sensor stops sending will not help. What does the serial debug output say on the two nodes? But if you still want to try, stop the gateway, modify MyConfig.h and re-compile and re-install the serial gateway. Then start the gateway again.

  @TheoL Absolutely you can use it in a presentation. It might be useful (or not) to know that node 105 is a refrigerator/freezer combo, node 102 and 103 are in the same refrigerator/freezer, and node 100 is a chest freezer I have an external thermostat on and I use it as a refrigerator.

  @vikasjee it could probably be done with the ESP, or the new GW device for the "masses", that is coming later this year. It is build on a atmel SAMD (same MCU as used on arduino Zero), currently being evaluated by our manufacturing partner in China.

  I have a generic multi meter, but I was not able to measure the current with this. I'm not sure why, I put it between the battery and the final connection terminal of the battery compartment.

  @Dick easiest way to fix is probably to uncomment #define CHILD_ID_RELAYWITHACTUATOR 5 and change msg[i].sensor = i; gw.present(i, S_LIGHT); to msg[i].sensor = CHILD_ID_RELAYWITHACTUATOR; gw.present(CHILD_ID_RELAYWITHACTUATOR, S_LIGHT); // quick workaround, only works for 1 relay That will break if you start using more than one relay though, so keep that in mind if you expand the sketch in the future

  I can only give you my personal advice. Since you're on this forum, I expect that you are interested in sensors and stuff. In that case. Download this library and look at the examples. Try to understand them and try to adjust them slightly. But, maybe it is a better idea to google "c++ tutorial". Arduino is C++ based. And this will definitely teach you the basics of the language. Last, try to look at the Arduino website.

  @chuckconnors We moved a lot of examples to a separate repository on GH during our release, as we can't have all the 3rd party libraries distributed with the core.. This is located at https://github.com/mysensors/MySensorsArduinoExamples, where you can find lot's of examples (all of them is updated to 2.0.0)

  @tbowmo Thanks for the reply. I'm still a newbie with all this. I think that I have 2.0 installed but most of the code examples I see or have used in the past are not 2.0 . Can you tell me how to install the older library and get rid of the newer one? Basically I'd just like to be able to upload the code I've used before to the new nodes.

  Right now it's arduino based. We are thinking about possibilities to separate us from that build environment, because it's so weird.. The only problem is that arduino is so popular with newcomers to programming and hardware, and for them it's relatively easy to use. It's only the more seasoned developers that knows something better is out there, that complains I still use the arduino environment for the basic sketches, as it kind of works, and atom for core hacking. I've got a set of bash scripts to help me along, and use gdb for debugging in target (samd hw) I think there are some platform.io integrations as well, but haven't had the time to look into that. We want to reach out to as many as possible, and that's with arduino at the moment.

  Yes you can have as many as your controller supports. If you have nrf/rfm radios on your gateways they need to be on different channels (but it sounds like you'll only be using local sensors so this might not apply to your setup). I don't know if Domoticz has a limit on the number of ethernet gateways but I think you can add as many as you want to.

  The serial API (glue between gateway/controller) is documented here: https://www.mysensors.org/download/serial_api_20 You can see the messages sent at boot in the serial console. It's just sends the presentation and controller usually transmits unit configuration back to node. (Unless node requires an id which takes place prior to this.) Suggest you have a look at the (somewhat outdated) sample controller to get started https://github.com/mysensors/MySensorsSampleController

  @nemik said: My advice would be to visit Alibaba and try to find someone who sells the product most similar to what you want. Then reach out to them about modifying it and branding it for you. Some sell iBeacons and such in wristbands already, so it might not be too big of a stretch for them to customize it with some other electronics that you might have in mind. Good luck! Thanks!

  @moskovskiy82 could you describe why you want the average? Are you sure the median wouldn't be a better choice? Or letting the controller handle averaging, since it will have access to past events even if the sensor is restarted.

  Short answer: No. Slightly longer answer: If you are sleeping to conserve battery you would need to power down the radio, so even if MySensors supported interrupts there would never be an interrupt because the radio would be sleeping as well. The power requirements for the radio in receive mode are too high for battery use. Long answer: Read the following earlier threads on the same topic: https://forum.mysensors.org/topic/2852/arduino-sleep-wake-on-interrupt https://forum.mysensors.org/topic/676/interrupt-on-recieve-radio-data/ https://forum.mysensors.org/topic/1461/how-to-sleep-the-arduino-but-still-have-it-respond-to-the-vera https://forum.mysensors.org/topic/1250/wake-up-over-radio/ https://forum.mysensors.org/topic/3100/low-power-servo-actuator/

  @y4CdW42Ol8 Have a look at the examples as supplied with the mySensors library. Both ways are implemented extensively. The gw.sleep(...) function will be the way to go for the 12 hrs. you'd like to put the sensor asleep. This is used in many examples For waking up with interrupt have a look at the example for the power meter. It wakes up the sensor when an interrupt occurs. Be my guest to find your own way of programming this, but as @mfalkvidd already pointed out: MySensors has its own functions! Good luck, Boozz.

  The controller can use the debug serial output from the gateway of type internal message subtype 9, I_LOG_MESSAGE, and report it in a log.

  MySensors is primarily wireless, but not wifi (as in wireless IEEE 802.11). We do have wired options as well with RS485 / RS232 I do not think that ethernet (as in IEEE 802.3) is the best option for sensor networks for home-sensors, It requires too many wires to each sensor point, and too complex transciever hardware on each sensor node. RS485 is more suitable for this purpose.
