  I was wondering about this but currently don't have any nodes that need to report errors. I thought though I would wrap the error in a string including a prefix as well as importance of the error and send it back to the controller via S_VAR I use MQTT gateway and I would have NodeRed listen out for any string with the prefix and send me an alert or log the event depending on the importance. Just an idea at the moment but might help you.

  @sghazagh yes. It can be a wifi gateway with a sensor (for example a temperature sensor) wired directly to it, without any nrf or rfm radio.

  @pbcstudios Well, that's my opinion also about Android version - sometimes it can make things worse with new bugs that overcome the few new features that's been added. @tandobkhcm Well, i didn't try any sketch for now with the v2 version so i can't tell. Also my humidity sketch is one of the sketches i didn't modify. My mods include combining several sensors into one node (e.g. 2 door sensor , one dht, one dallas temp), Or reading industrial sensors of pressure and EC through 4-20ma protocol and sending them as "temperature" readings because they have the longest log in domoticz.

  Hi! Thanks for help, now it works perfect Posting updated code: /** 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. Each repeater and gateway builds a routing tables in EEPROM which keeps track of the network topology allowing messages to be routed to nodes.

  @darkhorse Don't worry.. the number of nrf24 pipes has nothing to do with the number of modules. These all use the same channel. You are limted only by the max number of nodes 256 -2 = 254 (0 and 255 are reserved)

  @parachutesj I'm running a 2.0 gateway a couple of weeks now. It's stable and all 1.5 nodes still work flawless. Of course no guaranty that the all 1.5 nodes will keep working for others as well, once they've updated the gateway to 2.0. So I bumped one of my 1.5 nodes to 2.0 tonight. Will continue to do so with the others. First the easy ones (like temp and humidity sensors) then the others. Also great possibility to refactor the older ones to my current insights Already started some interesting projects with the new 2.0 features. Did I already mentioned that I love 2.0?

  @Mark-Swift In the sensebender sketch I replaced gw.send(msgTemp.set(temperature,1)); with if(gw.send(msgTemp.set(temperature,1))) { digitalWrite(LED_PIN,LOW); } else { digitalWrite(LED_PIN,HIGH); } LED is OFF if meassages are successfully delivered. LED turns ON if meassage delivery fails and stays ON until a new meassage is successfully delivered. Note that I use mysensors 1.5 as I did not yet update to mysensors 2.0. In 2.0 gw. is not needed

  @MikeF Good to hear that it worked for you. Possible just coincidence that it worked in V1.5. Reception of information on battery powered nodes is always an issue. The radio consumes a lot of energy while listening. There are a few new options in V2 to get around that. Take a look at the "Sleeping" section of the API Description

  Thanks for the reply.. It seems that if you can do what you did with the sensor code, presumably it should work with the gateway code, so I guess I just need to make some time to try some more.. Otherwise I think i'm just going to have to move back to a bigger arduino and just use an NRF and forget about the wifi on the new version.. Thanks!

  @pjr V_HVAC_SETPOINT_HEAT comes closest to what I need but is still related to the sensor/actuator variable that is being controlled. I also need to send parameters that are totally unrelated to any of the sensor/actuator variables. This could f.i. be the cycle time of the measurements, whether or not sleep mode is used, ... I launched a feature request in meantime.

  @chrille the fact that it works for nrf24, but not for rfm69 seems very strange as there are no indication-related calls in either radio code. The gw_rx and gw_rx indications are generated for valid message exchange on the gateway interface (Ethernet, serial, mqtt), while regular TX and rx indications are for valid message exchange by the connected radio (nrf24, rfm69).

  Ive started out with openHAB2. I was using a Ethernet gateway and tested the mysensors binding but found the combo was too limited. I much prefer having the MQTT gateway and the data be accessible to anything that subscribes, although I also now use openHAB to republish its item changes to MQTT as well which is probably a better approach. I don't think the main new features in version 2 are very mature at the moment as well, discovered things for example get put in to a non human readable database and the web ui's are not fully functional. With that being said I'm using node red to provide node ID's and configuring items manually and since beta3 it's been solid as a rock.

  @Sergio-Rius delay is actually the easiest way to do it Either that, or build a hardware debouncer. See also https://www.mysensors.org/build/binary for how to use the bounce2 library to handle debouncing. That solution doesn't support interrupts though, so delay is probably a better solution for your node.

  I have tried different things, the thing I have changed, is the type of value who would be send from the sensor. The default : send(msg.setSensor(i).set(temperature,1)); gives me the following error in Control 4 : number 1 string UPDATE parent 26 room 1 subcategory 0 [string "Lua Code"]:120: bad argument #1 to 'SetVariable' (strValue should be a string) (ReceivedFromProxy) altid 5;0 id 40 temperature 23.5 I tried to add the lines : char charVal[6]; //temporarily holds data from vals dtostrf(temperature,6,1,charVal); and changed the send to : send(msg.setSensor(i).set(charVal)); But the same happens If I cast the temperature to int I got the it, but without decimals If I try with : String string = "24,8"; send(msg.setSensor(i).set(string)); No error in Control4, but the sent temperature is 1

  That I am not 100% sure of. I would guess yes, but would think minimal. I would think the more troublesome area would be on the monitoring node, simulating a message to mysensors.

  I was doing that once but in my case it was not the best solution. I have some nodes on battery and so they don't ask for ack. I would need confirmation but I think that if my repeater is not reliable (far from gateway or somewhere with bad reception) It could add some loss on the communications from final node to gateway. I try so to test different place using this: https://forum.mysensors.org/topic/3984/nrf24l01-connection-quality-meter to place strategically my repeater.

  Yes, but only if there is one hop between your node and the gateway. If you have a repeater in between, you'll have to ask for ack and do resent if the ack-message hasn't arrived after some timeout.

  @tekka, yes, sorry, should have clarified. 7 bytes for MYS sensor, but the 6 bytes I was referring to as a "header" was the typedef on the firmware download. So 7+6=13/32 leaving up to 19 bytes for the firmware block itself. Thanks for the clarification on the padding and the CRC. That will become important.

  @Jasper-van-Winden the wait has helped in many cases. Nobody is 100% sure why. Maybe it gives the capacitors and the power supply time to recover from the power used when sending. Maybe it is somethong else. But it often helps

  @xydix Arduino using Atmega can supply max 40mA per pin, and in total max 100mA. DS18B20 seems to use max 1,5mA so yes this will work After searching on the net. https://github.com/nathanchantrell/TinyTX/blob/master/TinyTX_DS18B20/TinyTX_DS18B20.ino The part for the power on, read, power off is below (taken from the above link): void loop() { digitalWrite(ONE_WIRE_POWER, HIGH); // turn DS18B20 sensor on //Sleepy::loseSomeTime(5); // Allow 5ms for the sensor to be ready delay(5); // The above doesn't seem to work for everyone (why?) sensors.begin(); //start up temp sensor sensors.requestTemperatures(); // Get the temperature tinytx.temp=(sensors.getTempCByIndex(0)*100); // Read first sensor and convert to integer, reversed at receiving end digitalWrite(ONE_WIRE_POWER, LOW); // turn DS18B20 off

  @jkandasa said: It is necessary in some cases, Smart-sleep recently added, before when node wake-up get some date(adjust sleep duration) from controller with request Yep .. but this would be even more useful if one node could query other nodes data and receive the resonse from the controller (if the other node is sleeping). Again .. my proposal is to differentiate between: Request data from controller (for any other node, including gateway) ( = history query of most recent update the controller knows about) Request data from destination node ( = live query ) Edit: I just discovered resource groups on mycontroller .. think this will help out a lot with my planned workaround Edit2: I could not help myself and request an improvement: https://github.com/mysensors/MySensors/issues/574

Both results with MY_DEBUG defined. Next step is to create classes to manage switches, relays and LEDs. Once again thank you all for the help and fell free to share your opinions about the way I'm trying to do things. Best regards

  @mfalkvidd Thank you for your valuable suggestions - they all look very relevant. Perhaps I am overlooking something in the documentation, but I wonder if any existing controllers out there will get the node's relay outputs in the right state again after a node restart, if it always starts up in off state. Besides that, how can I reliably detect communication in the node, such as I_HEARTBEAT/I_HEARTBEAT_RESPONSE? As far as I know, such internal messages do not arrive through the recieve(...) API function. I will need to see some incoming messages (also from existing controller implementations) - otherwise I would get timeouts. Best regards Lasse

  Me neither. I care about security, not obscurity. I see no reason to encrypt a '1' or a '0' and digital streams like audio and video is not supported anyway. But exchange of constant (but random) data is already used and supported since signing is based on nonce exchange. But I believe IV:s "evolve" with the messages encrypted which implies the messages need to be exchanged trustworthy and sender and receiver need to be om sync. But I know to little about that to be sure. In any case, I welcome any development that adds to security, and will happily review such code, but I don't have the bandwidth nor motivation to "drive" the development of encryption in the core library as I don't feel it adds enough value to be worth the effort.

  @hek Sorry for my Late reply. I had an issue with the max485 (ground problem) and the declaration of the node id (was at the wrong position in the sketch). I think, it would be better, if this is also in the examples in the ms library. It cost me some time to find this solution for the node id. But i wasn't sure, if it was the parent or node id

  Thanks, I will most likely do it like you are suggesting. About reset, you mean setting it to "off" state after click or? The code above sends only one action per press, so it is either as "click", or a "double click" or a "hold released" (you can even send a "hold started" and "I'm holding...I'm holding...I'm holding...I'm holding..." events, but I do not need them for now). All the logic about counting etc is nicely handled by the OneButtonLibrary, it works much much better then the other solutions I found on the net (I even started writing my own logic, but being somewhat "experienced" developer I figured that someone has allready tested it better then me, and I was right ) I use domoticz as controller and it has option for the "contact" type of switch, which gets triggererd each time I press the button/send the ON state. It works nice so far, so I wasn't going much into details about hows and whys

  @bjacobse Yes, wdt business can be quite confusing Optiboot has a sophisticated wdt approach: wdt is only enabled if the MCU is reset externally (this is the case when you upload a new sketch from the IDE), in all other reset cases (i.e. watchdog-, brownout- and power-on reset), the wdt is disabled and optiboot directly hands over to the sketch. See here for the conditions: https://github.com/Optiboot/optiboot/blob/master/optiboot/bootloaders/optiboot/optiboot.c#L484-L485 And here it gets disabled: https://github.com/Optiboot/optiboot/blob/master/optiboot/bootloaders/optiboot/optiboot.c#L847 This also means that with optiboot, wdt is always disabled when the sketch starts (if WDON fuse is unset). And to give a heads up for the MYSBootloader 1.3 release: wdt will be on by default (at the moment 4s), and the user has to either disable or reset it in the sketch. This is a safety mechanism and the only way to remotely recover from a bad/faulty FW.

  Dear @Konstantin-Kolesnichenko, This behaviour has got nothing to do with the 2.0 version. It's the same in the previous version of MySensors. Node's need communication with the gateway before they can start. I'm closing this topic. See https://forum.mysensors.org/topic/4449/how-to-disable-default-node-registration-to-the-gw/2. It's a thread about the same topic.

  @korttoma said: Try running the "ClearEepromConfig" example sketch from MySensors examples and then try your sketch again. Might be that there is an old "NODE_ID" being used that is conflicting with another node. If you want to use static NODE_ID you should put the following before the MySensors.h include in your sketch: #define MY_NODE_ID 14 You are also stil missing the #define MY_RADIO_NRF24 Before the MySensors include that @hek pointed out. ^^ this - I've had this happen before (just last night actually) but i recalled from when it happened in the past, found out it was using a dupe ID, ran eeprom sketch.. good to go now.

  I've now tried various algorithms. In all of these I set the oversampling of both temperature and pressure to 1 (no oversampling). Forced mode, with fixed 5mS delay between reads, Forced mode, with fixed 4mS delay between reads, Forced mode, with fixed 3mS delay between reads, Forced mode, with fixed 1mS delay between reads, Normal mode, set t_sb = 0.5 mS, waiting until status bit 3 = 0, read data, repeat Normal mode, set t_sb = 0.5 mS, waiting until status bit 3 = 0, read data, wait until status bit 3 = 1, repeat With each algorithm, I'd do 2000 reads. As I went through the above scenarios, the minimum and maximum readings (for both values) got farther and farter apart - ie: the range of values got larger. That was until #5, where it was slightly better then #1. The range with #6 was the least of all - in other words, algorithm 6 gave the most consistent readings (I should say the sensor is laying still throughout these tests). In #5, it took 6 seconds to make 2000 readings - or an ODR of about 333 hz. In #6, it took 12 seconds to make 2000 readings - or an ODR of 166 hz. Just what the datasheet said would be the maximum ODR. I have to assume with #5, about half the readings were done before the registers were updated. In other words, it was a waste of cpu time to make the reading.

  @TheoL Hi. I think that a higher level of abstraction from the controller, and giving the node more personality suits better for me. Also I like reducing the unnecessary radio traffic. Let me explain something more my node. The node I'm working on it's basically a multiple actuator that abstracts from the code things like the number of relays or their behaviour. At the moment, you are forced to populate a collection for it to discover and work with a variable number of elements, but as soon as I can I'll find a way to inject that info and avoid altering the code. Perhaps something like espeasy does, rflink activates it's rf modules, or even through a variable from the controller (worst of cases) Now it does all those things but the timer shutdown. I'm a good C# programmer, but I admit that it'll be difficult for me to adapt to C++. I still do all the things as I was doing in C# I don't know anything about the scope or the behaviour of instantiated objects. I would like to tie a timer object to one element's property in the collection and let it run, but I don't know how, or if it will stay "alive" after the procedure ends

E.g. gw.present( TEMP1_CHILD_ID, S_TEMP, "DHT1 sensor", true ); // present to controller gw.present( TEMP2_CHILD_ID, S_TEMP, "DHT2 sensor", true ); // present to controller By doing this I can see the description in Domoticz, so that I know what to add.

  So I'm new to all this, however anytime I get funky things going on when I have multiple sensors on a node I found that introducing a delay in between the readings helped smooth things out. Hopefully someone will correct me if I'm wrong, but I have had some luck with delays. Also I built one to control my hot tub and I found noise from the pump messed things up, de-coupling capacitors became my friend after that.

  @mfalkvidd said: It depends on how much work you are prepared to do and how much flexibility you want in the code. If you only use one temperature sensor and don't have any plans to add more, change gw.send(msg.setSensor(i).set(temperature,1)); gw.send(msg.set(temperature,1)); Only using the ph sensor and 1 temperatuur sensor no need for more temp sensors.

  Yes I got that from the examples. But my question is: on the gateway itself, which has to do something to talk to the other nodes (?). If I add a sensor to the gateway itself, then what do I do? Can I use sleep()? will the gateway function properly? Ok I tried wait(), for some reason wait() did not worked before, (got only one message) now it works...

  @hek Thanks -- one other quick question: am I right in assuming a child sensors will only ever send "set" message types and will only be routed "req" types? For example, I'll never see a message like this: 3; 3; 3; 0; 9; etc right? Nodes would send that sort of message, but never a child: 3; 255; 3; 0; 9; etc yes? I'm assuming this because most nodes just report a setting or get set to something, they don't have any intelligence beyond that, that all exists on the child's node.

  @linus72982 The GW doesn't keep track of which nodes that is connected. It only acts as a GW between your sensor network and your controller.. The presentation messages that you see in your controller, is coming directly from the node itself. Your controller should cache the node presentations. As it's the controllers job to assign node-id's they won't change if the GW is rebooted.

OK, thanks, I didn't realize that. In my RF24 setup I am defining the Channel to use in all nodes the Channel so it should be OK then. I will seek out how to define the Channel for MySensors and stay well away from RF24.

  @Skye-Turner Ok thanks, was hoping there was still a system board there; was hoping it would be as easy as this for you. As for ideas, you could use an Arduino Uno, Nano, or Mega and have all your sensors connect via external pull-up resistors to deliver a good clean signal. You can just use the example ReedSwitch sketch and just modify it for how ever many binary/reed switches you want to have. Also now that MySensors is on V2.0, you can use whatever method you choose to communicate to HA (NRF/RFM, Ethernet (Gateway and NODE on same Arduino), etc. I think even Wifi with the ESP8266 is an option. How do you intend on communicating your sensors with HA? Do you have an existing MySensors network?

  @GertSanders I think there is a better chance that the controller is going to be online. I have a mini UPS on my RPi for example if there are no mains supply. I also have a device pinging the controller and if it is not responding sending the halt/reboot signal to the RPi. If your node is working an a universal GSM gateway, that's a different story though. But does it have a power (battery) backup in case there is a blackout ?

  What payload do you send in the message? Each scene controller can have multiple buttons. Example: MyMessage msg1(CHILD_ID_3,V_SCENE_ON); MyMessage msg2(CHILD_ID_3,V_SCENE_OFF); send(msg1.set(1)); // Turn on scene button 1 send(msg2.set(1)); // Turn off scene button 1 send(msg1.set(2)); // Turn on scene button 2 send(msg2.set(2)); // Turn off scene button 2

It's really hard to help you with a sketch if this size. You could try to give the debouncer a higher interval, e.g.: debouncer2.interval(25); Thanks for the troubleshooting tip! @mfalkvidd After commenting out almost all of the LCD/temp functions i was left with the last wait that caused the problems, it seems to be working now but havent got the time to run it more than a few minutes.

  @NickBuilder said: Thank you @mfalkvidd for the very educational description. I thought that the check could have been as you described but I felt that it was too crude and simple. This doesn't seem to be the most typical use of "exclusive or" but I guess it does the job. There are more advanced ways. This scheme will not detect two bit errors in the same group (even or odd) and it can only detect errors, not correct them. But without knowing the reasoning behind the design it is impossible to say if it was a bad choice or not. Is it common to only include part of the transmission packet in the parity check? I would have assumed that the nib (Nib4) should be part of the bit check and that the parity bits would then be set or not set so that the complete packet is confirmed. Yes, it is common to exclude things. What things depends on the use case. From what I understand, the exact same message is always sent three times. If the z-bits were included in the checksum, a new checksum would have to be calculated for each time the message is sent. That would probably have a negative effect on the communication speed and would add complexity to the solution without adding any real benefit. If the checksum bits themselves (C) were included in the checksum calculation they would affect the checksum so the checksum would change so the checksum would have to be calculated again which would cause the checksum to change so the checksum would have to be calculated again and so on.

  @NeverDie Yes, you are correct - it is based on ATMega1284P. So not relevant My point is that I'd rather stick to the datasheet rather than overclock, but that's just me. And yes I realise that Moteino is overclocking, but the size, voltage and flash are really appealing to me.

  This is still in an alpha state and ESP8266 development may take some time. This is a TFT screen with the daughter board:

  Ok I got it to work. I misunderstood how the interrupts worked. Got it now. The culprit was the if statement detecting if the state changed. Since the state was being maintained while sleep, it wasn't firing when I pushed the button. Thanks for everyones help!!

  Thank you. That will get it right. But now I get the delay when the door open. I guess I need a pull down resistor for this to work. 4.7k? 10k? I guess it's the internal pull up that consumes power? Another thing. I changed digitalWrite = HIGH (original example) to Pinmode INPUT_PULLUP in my first sketch Wich option is best if I want low power consumption?

  @tomkxy it is a few mA while sleeping. This means that it has to be modified (no VDO and no LED) - consumption drops to a reasonable 160uA or even below.

  @abmantis It seems related, but I haven't looked deeper into why. I guess this ought to be addressed in the PR so that the counter is increased +1 always. But we should find the cause first.

  @tomkxy The concept of whitelisting I have developed is to protect from the case when someone actually obtained your key. Typically by stealing a node with a personalized ATSHA onboard or even one with soft signing. According to Atmel, it is not possible to extract the HMAC key from an ATSHA but it is from a software based node. For this reason, my recommendation is to never use soft signing for nodes "outside". Now, although it is not considered possible to extract the HMAC key from an ATSHA, the attacker can still use it as it is already personalized for you. So he can just flash whatever and be able to send valid signatures. However, if you enforce whitelisting on your network, then the receiver of signed messages has to keep a list where each node is listed, and with each node a unique serial. That serial is salted into the signature by the sender and therefore not sniffable. But the attacker will be able to determine the serial from the node stolen. But using that info, he will not be able to deduce the serial of other nodes in the system that you also have decided to accept. So if you detect that a node has been stolen, you remove it from your whitelist, and the attacker will then have to guess both the nodeId and the serial of a node in your whitelist table. The nodeId can be sniffed, but the serial cannot. And therefore I do not under any circumstance allow the serial to be easily accessible by any means.

  @hek This is pity. This means that I am going to loose a lot of historical information unless I want to manually copy and paste values in the DB. At least it makes an order - one id per node.

  @Maurizio-Collu I've had it running by using the pin layout as described in the wiki site in my previous post. Of course I had to change the CS(N) pin in MyConfig.h (CS-pin to 53). Don't forget to put it back to original if you're using it on other arduino types !! As far as I can remember (it was more that a year ago when I tried this) that was the only change needed to get it working. See table below; use Mega2560 with RF24 library. Hope this helps. Boozz

  @derksuh Ok, but it still needs your code to find a place within the loop if I'm not mistaken? I'm not a c-programmer, so now and then I'm somewhat confused by the code of others. I learn by doing, which is now and then a process of copy-paste and at other moments analysing how others did it. BR, Boozz

  hello. at the beginning of your sketch, you can add #define MY_NODE_ID x where "x" is your node id. If this line is commented, or not present, then it's auto mode.

  @AWI The code is from the MySensors examples and i use it to control 3 mosfets that controls a ledstrip. I need the heartbeat because i use the RPi gateway with the NRF24 chip directly connected to the RPi, and the gateway software for the raspberry dont store the network map so if i reboot the RPi the nodes loose connection to the gateway.

  @lafleur I have also updated my local RFM69 library to the latest version with some additional changes to solve issues with acknowledgements not being received. If you're interested, you can see my conclusion here: https://forum.mysensors.org/topic/3663/testing-development-branch-with-rf69hw-is-not-working-as-it-should/12 I also link to a separate thread over at the low-power forum where things are discussed in more detail. If we are planning to upgrade the RFM library I propose that we include the fix I found. The only problem is that this fix is mostly a temporary solution, so perhaps it is better to wait until the issue is fixed in the library itself.

  @Mr.Osaka no worries. Thank you. Yes, the signing solution on development branch (which will be part of the next major release) is much easier to work with. Both with personalization, use and any maintenance required. It will also make node to node signing easier to initiate.

  @macieiks I don't think you're question is really related to MySensors, it's more an Arduino related question. The problem you might have is the memory capacity of the Arduino. Here's the sketch for the first mySensor node I made. It uses an I2C lux and i2c barometric pressure sensor and an HDT11 humidity sensor. /** * 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. Each * repeater and gateway builds a routing tables in EEPROM which keeps track of the * network topology allowing messages to be routed to nodes. * * Created by Henrik Ekblad <henrik.ekblad@mysensors.org> * Copyright (C) 2013-2015 Sensnology AB * Full contributor list: https://github.com/mysensors/Arduino/graphs/contributors * * Documentation: http://www.mysensors.org * Support Forum: http://forum.mysensors.org * * This program is free software; you can redistribute it and/or * modify it under the terms of the GNU General Public License * version 2 as published by the Free Software Foundation. * ******************************* * * REVISION HISTORY * Version 1.0 - Henrik EKblad * * DESCRIPTION * This sketch provides an example how to implement a humidity/temperature * sensor using DHT11/DHT-22 * http://www.mysensors.org/build/humidity */ // #define DEBUG #include <SPI.h> #include <MySensor.h> #include <DHT.h> #include <Wire.h> #include <Adafruit_BMP085.h> #include <Adafruit_TSL2561_U.h> #include <Adafruit_Sensor.h> #define CHILD_ID_HUM 0 #define CHILD_ID_TEMP 1 #define CHILD_ID_BARO 2 #define CHILD_ID_LIGHT 3 #define HUMIDITY_SENSOR_DIGITAL_PIN 3 const float ALTITUDE = 28; // <-- adapt this value to your own location's altitude.

  Also contra: no signing

  error No forward link or gateway feature activated. This means nowhere to send messages! Pretty pointless.

  Well you could store the boolean variables for the valves in an array, and use the sensor child id as the index of the variables in the array. You can also use the setSensor setter on the message variable (MSG_V1) to change which sensor child id the message belongs to. That way, you only need to declare one message variable. You can use two setters on the same line like this: // Set child id 1 to 0 to simplify using it as index in an array #define CHILD_ID1 0 // Set child id 2 to 1 which is the next index after index 0. #define CHILD_ID2 1 // Declare an array of type boolean of size 2. boolean VALVES[2]; // Declare the message with CHILD_ID1. MyMessage MSG(CHILD_ID1, V_LIGHT); void setup() { ... } ... void incomingMessage(const MyMessage &message) { if (message.type == V_LIGHT) { // Set array element at index message.sensor to boolean value from message payload. VALVES[message.sensor] = message.getBool(); // Set child id to child id of message.sensor and payload to either 1 or 0 for message, and send message. gw.send(MSG.setSensor(message.sensor).set(message.getBool() ? 1 : 0)); } } Sorry... there was a lot of edits. Now I'm done....
