I'm not sure if this is the right place to ask. But it seems right to me
Hi I have e few of the Easy/Newbie-pcb working for some time with good effort. One of them even in a shed at 20 - 25 meters in the garden which is fairly good isolated. Sending Temp/Hum/battery level. And the Gateway is in the house on the first floor behind a door in a wardrobe.

Now I have a second shed which is behind the fist shed. Also very good isolated. The pcb I have in there is not reaching the gateway (it did before until the battery was empty).
Can I have the pcb in the first shed also working as an extender, so the second pcb will be able to send out topics to the gateway as well? What to add to my code to achieve that?

@mfalkvidd said in What is loaded / running on the arduino?:

@mr_sensor you are correct that it is not possible to get the sketch from the Arduino.

But all MySensors sketches have something like this:

sendSketchInfo("TemperatureAndHumidity", "1.1");

which identifies which type of sketch and the version of that sketch, every time the sensor is restarted. If you store your sketches in some version control system (git is most popular), keeping track of them becomes quite easy.

See also https://forum.mysensors.org/topic/2203/method-to-reveal-sketch-inside-node-or-g-w for an earlier discussion on a similar topic.

@mfalkvidd thanks for the reply. The sendSketchInfo is indeed helpfull will also read the link.

Just a question that is on my mind for some time now. When a sketch is loaded on a arduino (in my case a pro mini) how to see / find out what is on that board? Or is that even not possible?
After some time running a node and building others in the mean time it is not always clear what is on the particular node. Dis I miss something basic here? Or is it just not possible getting the (sketch) info from the arduino?
How are you dealing with it. Having a sketch named/ numbered for every node? Just wondering what is the best practise.

Well the NACKS are gone by setting the RF_24_PA_HIGH but still I do not get any temperature after the first one while starting up:

I have a newbie-pcb board with a Dallas temperature sensor attached. I mixed some sketches together to make it work.
When starting the sensor the first time I can see all the actions performed. Reading temperature and battery percentage. But than after sleeping it is only reading and sending battery percentage (no voltage)? No temperature action is visible any-more. So, there must be a fault in my sketch which makes it read the temperature part only once? Any advice on this? Thanks.

@gohan said in Easy/Newbie PCB (RFM69 HW/W edition) for MySensors:

but this is RFM69 radio pcb not NRF24
I know but I am using the nrf24 pcb.

Do I need to add something like this when using the AP version?

#define MY_RADIO_NRF24

#define MY_RF24_PA_LEVEL RF24_PA_HIGH

Or just #define MY_RADIO_NRF24

@gohan Ok, what do you mean by "define HW" in code" ? This in my code:
#define MY_RADIO_NRF24

@mr_sensor said in Easy/Newbie PCB (RFM69 HW/W edition) for MySensors:

@sundberg84 @gohan Ok thanks for the input I will order some of the extended ones and see if thing s will improve.

The parts mentioned above arrived. I thought just swapping the radio's and see if there is any improvement. But it seems my devices are not happy with there new radio ? So are these new devices coming with the same pin-out and are they using the same library as the non amplified radio"s ? Or do I need to alter my sketches or wiring for it to work?

@sundberg84 @gohan Ok thanks for the input I will order some of the extended ones and see if thing s will improve.

@gohan said in Easy/Newbie PCB (RFM69 HW/W edition) for MySensors:

I would get better quality nrf24 modules and using a PA LNA one on the gateway may also help. Sure the rfm69 at 433MHz can have a better wall penetration, but I think you can do with better radios. Look for CDEByte store on aliexpress, they have good radio modules. Also a poor quality power supply can reduce the effective range.
If you want to try the RFM69 radios, you can "convert" the ones you have with this https://www.mysensors.org/hardware/nrf2rfm69

So these would be better?

If I use one with PA_LNA on my Gateway are the pin-out the same as for the nrf24l+ as in the mysensors gatweay example?
Also there are models with nrf24l+PA what is the difference with the nrf24l+ ones?

Everything is going fine so im taking this to the next level... from test to produktion.
This sensor might be my most important summer sensor from now on
A couple of days ago I had some friends over which gave me a beer cooler, garden edition.
Its pretty much a barrel in the ground which cools the beer down... (a bit atleast).

I must say Im very impressed with the RFM69 so far... except the price, there has been no trouble at all. No repeaters, no capacitors, no fine tuning... nothing. Pretty much solder 'n' play!

This node is burried in the far end on the garden (25m) and has to penetrate 3 concrete + 1brick wall to reach the GW in the celler... no problems, first try and bang!

So far... the temperature in the cooler isnt very impressive, and I have only tried the first layer. I was afraid I would loose radio coverage if I put the sensors far down... but I will try.

Cheers mates!

Hi, nice set-up. I have been reading this and havong a "newbie" question. I have a Newbie PCB build with the Nrf24l01+ which seems to give (me) a poor range.
So would that improve having a rfm69 instead? Or will just adding an antenna improve the reach (I have more or less the same outside distance and concrete wall/ flooring I'd liek to cross). Now I just have a reach for approx 8 meters and one concrete floor (inside the house)? Which is not very good (even my z-wave devices are preforming much better - outside at 20 mtr from the house.
Can the nrf240 be improved or do I need teh rfm69 (or even using a LORA ?).

@sundberg84 Ok did try with just the bare pro mini + the temp sensor + resistor on a breadboard powered with 3.3v from ftdi adapter.
And guess what? Than I get the temperature reading So why is it not working on the board than? I Will check the soldering again and see if I can solder a new board.

So both sensor and arduino are working?

@sundberg84 I tried with other libraries, without success. Also changed the sensor for a new one, without any success. Only thing that made me wondering, now the sensor is on 3,3 volt? When looking at the net for samples, etc. some of them refer to 5volt? So could that be the problem here? Not providing 5 volt to the sensor?

@sundberg84 I did measure some things. Also replaced the arduino to be sure that it was working (did nt make a difference)

I found 3,3 volt between vcc and gnd on the sensor. Also between the data-pin of the sensor and the arduino there is continuity.
The middle leg on the sensor and GND + VCC on the PCB is not resulting in any continuity(I am not really sure if I did measure it in the right way. It is a bit hard to get gnd + vcc on the multimeter pin together).

@gohan Not a solder problem I think. This is no short on the board it is just the angel of the picture hiding the gap underneath.
tried the same set-up with an other dallas sensor. still the same result.

@mr_sensor And show a pic of the bottom of the board with the sensor.

@sundberg84 I run the "single" sketch from temp library and this is what I get:

@sundberg84 Yes thanks I did so. But do not get any temp read out? Have al in space also the 4,7 k resistor.

@gohan said in Easy/Newbie PCB for MySensors:

you can add a wire to the I2C pins, in your case you just need a short wire to a digital pin that are just next to the Extra area

Ok. And if attaching a DS18B20 I have a pull up resistor soldered on the board. Than it is also just the digital pin I need from the board? D3 I think?

@sundberg84 I have a "newby" question about how to use the Extra's part of the board. If I want to connect a DS18B20 sensor per example can I just solder it on the extra area and connect is with some wires to the pinout I need?
Asking this because I did this with the i2c sensor on the board discussed here. having a wire form the extras towards the arduino i2c pins directly. Later I discovered that the i2c pins are also on the board.
So how to deal with this?

@sundberg84 Well I tried that but did not get the measurement straight from the pcb si I decided t solder a new board using the right capacitor this time (0,1uf instead of 1uf) made sure using the right resistors as well and adding a capacitor after the booster. Than with the same mini pro from the other board tested again and wow it is working as intended.

But not the voltage?

@gohan said in Easy/Newbie PCB for MySensors:

you are also missing the capacitor on the booster output for better stability

Ok, I assumed it was not needed when using a battery. Which one to use there?

@gohan said in Easy/Newbie PCB for MySensors:

What are the resistor values you used? 0.1v is quite low

Maybe I used the wrong capacitor it says 1uf (50v) but now I see it has to be 0,1uf could that be the problem here?

@gohan said in Easy/Newbie PCB for MySensors:

Resistors can be soldered either way, but if you read 0v on that capacitor pin it mean you have a problem between the battery and the capacitor, so you have to backtrack the connection that is missing

I measured the capacitor again and get a 0,10 output.

@sundberg84 said in Easy/Newbie PCB for MySensors:

@mr_sensor - I can not see any errors on the pictures you posted.
Can you measure the voltage on Booster-Vout and also on this pad.

I did measure the parts you mentioned. Booster is 3,36 v and the other pad is 0,00 the input strait from the batteries is 2,80 v

Also, Just for my info, does it matter how the resistors or capacitors are soldered on the board? My biggest problem is always determine the right resistors value and the right way to solder them (+ -). On the pcb some of them are coded (very handy for me as a beginner) with a G but not all of them?
So my worry was that I maybe have soldered the "battery measurer" ones in the wring direction? Could that be the problem here?

@gohan said in Easy/Newbie PCB for MySensors:

I don't think it is PCB related, try to make sure it is not a faulty arduino

I already changed the arduino for a fresh soldered one but that did not alter things.

@sundberg84 Hi, I soldered a board holding a humidity and temperature sensor. That is working fine and reporting to may gateway (mqtt). Only thing which I do not get working ok is the battery level measurement. As I already posted in an other topic here.

Here are some pictures of my board. The bat jumper is connected with a wire on the bottom. And the code I use on it right now.
I already changed the pro mini for a fresh soldered one but still getting the the same result. Just ones giving the volt and % and after that only giving 0 volt as output.
tried to include delay(500) in the sketch but that did not help. So how to solve this?

@gohan Ok will try that see if I made a fault somewhere

Still not getting it working! Any thoughts on this?

@gohan

Arduino Pro or Pro Mini
Programmer AVR ISP
ATmega328P (3,3v 8mhz)

@gohan I'm using the EasyPCB board with an arduino pro mini 3,3v

@gohan said in How to get battery volt / percentage message send to mqtt?:

delay(500)

Hi, tried that (already tried it with wait). Now I added it here:

delay(500);
    int sensorValue = analogRead(BATTERY_SENSE_PIN);

Also tried it here:

 if (oldBatteryPcnt != batteryPcnt) {
        // Power up radio after sleep
        delay(500);       
        sendBatteryLevel(batteryPcnt);
        oldBatteryPcnt = batteryPcnt;
    } 
                                                                                                                                                                      
  sleep(SLEEP_TIME); //sleep a bit  ```

Both did not help still ending up with 0 . 
So what should be the best place the right place to put the delay?

@gohan Tried to find out what causing that but can not figure it out. I'm bot a real coderer so its trial and error and trying to understand form other sketches / posts. Any idea where to look for?

@yveaux changed the position of int oldBatteryPcnt = 0; outside of the loop and added the static prefix static int oldBatteryPcnt = 0;
Still not giving me the right result the first message seem ok but than it only has 0 ?

I Build a temp / hum sensor with the easyPcb board and Am able to get the temp and hum send to the Mqtt broker.
Next thing is to get the battery voltage and % send to the Mqtt broker as well.
Now that is giving me some problems. I merged the two scripts together, and tried to learn form other topics. But I'M not getting is right dough. This is my script right now:
Also the output of the serial monitor.
I have the feeling I am nearly there Any help would be great!

Ok found out what topic is send to mqtt turned out to be:
mygateway1-out/2/1/1/0/1 or mygateway1-out/2/0/1/0/1

How to get an % and "C" to this topic value?

Great! That helped a lot. I Kicked that out when reading the Converting a sketch from 1.5 to 2.x article.

Now I only have to find out what to use for mqtt to read this sensor values. Thats still not very clear to me:
Guess it would be something like:
mygateway1-out/2/2/0/0/ or 2/2/0/0/1 ?

Would it be possible to have something like this:

mygateway-out/2/2/Temperature ?

since I did not get these Dht11 or Dht22 working, I decided to try an other sensor type to see if that would work better.
So I connected a HTU21D sensor and included the library from sparkfun. Using there demo sketch I can see the sensor is working fine:

HTU21D Example!
Time:192 Temperature:20.8C Humidity:998.0%
Time:1318 Temperature:20.8C Humidity:47.3%
Time:2445 Temperature:20.7C Humidity:47.4%
Time:3571 Temperature:20.7C Humidity:47.4%
Time:4698 Temperature:20.7C Humidity:47.5%
Time:5824 Temperature:20.7C Humidity:47.5%
Time:6948 Temperature:20.7C Humidity:47.6%
Time:8075 Temperature:20.7C Humidity:47.6%
Time:9201 Temperature:20.7C Humidity:47.6%

But when I include the "adapted" Mysensors sketch I found here in the forum it seems the temperatures are not read or something else is wrong?

This is what is in the log file in a ongoing loop:

This is the sketch I use now I had to adopt it since it seemed to be for an older version of Mysensors. I'm no programmer so it might be messed up somehow

@Mr_sensor Stil get the message

Failed reading temperature from DHT!
Failed reading humidity from DHT

Also tried it with an dh22 I had (included a pull-up resistor between vcc and data) but get the same result. What can I do to get this working?
If I use the arduino pro mini for an other sensor they are working fine (tested with a magnet-reed switch).

@tonnerre33 No I have one with pcb.

@hek Thanks for the reply. I just did a test with my multimeter and measuring at the dht11 it shows 3.46 so that should be ok right?
I used the DHT11 some time ago with an esp8266 and than it was working fine. Could the pin 3 data be the problem?

Hi,

I'm trying to get my first sensor working. A DHT11 temp/ humidity sensor. I followed the instructions from the build part on Mysensors. Uploaded the sketch and had a look at the serial monitor.
There it appeared that no temperatures are coming up. So I had a look at the connections and all seems fine to me. What could be the problem? Power?
Also, having a look at the serial log, does it communicate with the gateway? I think so, but which lines are referring to that?
The parts with: TSF:MSG:READ,0-0-1,s=255,c=3,t=27,pt=1,l=1,sg=0:1 ?

Any advise on how to get the DHT11 to work? Thanks.

Using the DHTlibrary as mentioned in the instructions.
Arduino 1.8.2
Mysensors 2.1.1
Arduino pro mini ordered from aliexpress I am not sure which version I have both 3.3 volt and 5volt version (how to determine?).

Any help would be appreciated. Thanks. W.

Any ideas on this any one? How to troubleshoot this? Would be nice to get this working. Thanks

Hi, I'm a Homeseer user, and I lately discovered the MQTT plugin. Its maintained well and gives you the possibilities you might be looking for. I have seen other users having it in use with there sensors and even switches (sonoff)

Hi, just started to explore the MySensors possibilities. The first project I'm building is a High temperature MAX6675 Thermocouple which send data to the MQTT broker.

So I ordered some parts and started building the gateway with an arduino uno and Ethernet shield. Than connected the Max6675 and gave it a go!

Although the set-up seems to be quit simple I can not get any temperature read from the sensor?
If I connect it like some of the samples I found I end up with this:

Deg C = nan	 Deg F = nan
Deg C = nan	 Deg F = nan
Deg C = nan	 Deg F = nan
Deg C = nan	 Deg F = nan
Deg C = nan	 Deg F = nan

I used this example for the wiring: link to max6675-temp-module-wiring

Also had a look at the post about the max6675 here on the forum. After trying several combinations I run out of ideas. So maybe one of you can point me in the right direction to get this finally working

This is the sketch I ended up after changing it several times.

 * 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.

 *******************************
 *
 * REVISION HISTORY
 * Version 1.0 - Henrik Ekblad
 *
 * DESCRIPTION
 * The W5100 MQTT gateway sends radio network (or locally attached sensors) data to your MQTT broker.
 * The node also listens to MY_MQTT_TOPIC_PREFIX and sends out those messages to the radio network
 *
 * LED purposes:
 * - To use the feature, uncomment WITH_LEDS_BLINKING in MyConfig.h
 * - RX (green) - blink fast on radio message recieved. In inclusion mode will blink fast only on presentation recieved
 * - TX (yellow) - blink fast on radio message transmitted. In inclusion mode will blink slowly
 * - ERR (red) - fast blink on error during transmission error or recieve crc error
 *
 * See http://www.mysensors.org/build/esp8266_gateway for wiring instructions.
 * nRF24L01+  ESP8266
 * VCC        VCC
 * CE         GPIO4
 * CSN/CS     GPIO15
 * SCK        GPIO14
 * MISO       GPIO12
 * MOSI       GPIO13
 *
 * Not all ESP8266 modules have all pins available on their external interface.
 * This code has been tested on an ESP-12 module.
 * The ESP8266 requires a certain pin configuration to download code, and another one to run code:
 * - Connect REST (reset) via 10K pullup resistor to VCC, and via switch to GND ('reset switch')
 * - Connect GPIO15 via 10K pulldown resistor to GND
 * - Connect CH_PD via 10K resistor to VCC
 * - Connect GPIO2 via 10K resistor to VCC
 * - Connect GPIO0 via 10K resistor to VCC, and via switch to GND ('bootload switch')
 *
  * Inclusion mode button:
 * - Connect GPIO5 via switch to GND ('inclusion switch')
 *
 * Hardware SHA204 signing is currently not supported!
 *
 * Make sure to fill in your ssid and WiFi password below for ssid & pass.
