I'll try this as soon as possible. Although the ip network connection doesn't seem to be the issue since ip dedication is without problem.

What I have to mention: The setting was running great as a Serial Gateway config. But when I changed to ethernet gateway I was not able to restore this condition together with the W5100 shield. Moreover I don't know if the pin4 is making some trouble. As far as I know its used for writing to the sd card (which I don't use...).

This is what is coming out of the gateway debug:

Wow cool, so the hardware is basically running, but for some reason, the gateway doesn't accept the message.
I'll double-check the signing algorithm (perhaps I comment it to see, if there are arriving unsigned messages) and I will post the result.
Strange thing. Thank you very much!
I'll do this tonight.

Hi, I've cut present, setup and loop not to waist to much space. I edit and add them too...
Unfortunately as you can see, the gateway is not receiving anything and therefore not answering the node.
I will test with different hardware now, if there is something weird.

Hi,

I have trouble with my ethernet shield.
I tried different methods and there where different publications on how to connect, but in the end I was not able to get it running.
I tried: CE and CS pin on 6 and 5 with and without changing MISO/MOSI/SCK to A0 to A2, but the best result I got was an error free start of the gateway but not receiving any data from nodes so far (connection to ip network seems to be fine, at least the ip is declared via dhcp). The same setting was doing great without ethernet shield. Tried it also on a Mega but without success...
To sort out the power issue I put an extra 3.3 power regulator together with a big 470 microF capacitor which should do the trick.
Any ideas? I will post the exact wirings in a few minutes.

If you have one working in this setting, can you send me the exact sketch together with the wiring information?

Thank you!

Hi,
I was wondering if I could use the node red flows to attach mysensors to loxone. But I failed already in the first step: I don't get the my sensors software imported in node red.
Although I find the "Import" option in the UI, there is only little space and no specific name under library to depict what to import. So the left options are only clipboard and examples.
Could one of you experienced guys give me short push where i have to copy the files of the node-red-contrib-mysensors-master folder?
Thank you so much kd

thank you for the important hint.
Unfortunately it didn't solve the failure message. For my understanding the altsoftserial shouldn't be called since MY_RS485_ESPSERIAL is defined.

My code looks like this:

#define MY_DEBUG
// Enable RS485 transport layer
#define MY_RS485
// Define this to enables DE-pin management on defined pin
#define MY_RS485_DE_PIN 2
// Set RS485 baud rate to use
#define MY_RS485_BAUD_RATE 9600
SoftwareSerial swESP(14, 12, false, 256); 
#define MY_RS485_ESPSERIAL swESP

Hi,
I am just wondering, if it would be possible to use the esp8266 chip for wired projects with RS485. My intention is to use the form factor as well as power and mem space for small projects. Furthermore it would be possible to start the ESP with wlan connection for possible OTA update.
Because of the different softwareSerials tried to include the settings for ESP, but was not successful.
Please have a look. Do you see any problem in the following sketch files?

1. MyTransportRS485.cpp:

#if defined(MY_RS485_SWSERIAL)
SoftwareSerial& _dev = MY_RS485_SWSERIAL;
#elif defined(MY_RS485_ESPSERIAL)
SoftwareSerialESP& _dev = MY_RS485_ESPSERIAL;
#elif defined(__linux__)
SerialPort _dev = SerialPort(MY_RS485_HWSERIAL);
#elif defined(MY_RS485_HWSERIAL)
HardwareSerial& _dev = MY_RS485_HWSERIAL;
#else
AltSoftSerial _dev;
#endif

1. MotionSensorESP sample:

// ESP Software Serial
#include <SoftwareSerialESP.h>

// Enable debug prints to serial monitor
#define MY_DEBUG

// Enable RS485 transport layer
#define MY_RS485

// Define this to enables DE-pin management on defined pin
#define MY_RS485_DE_PIN 2

// Set RS485 baud rate to use
#define MY_RS485_BAUD_RATE 9600

// Enable this if RS485 is connected to a hardware serial port
//#define MY_RS485_HWSERIAL Serial1
//#define MY_RS485_ESPSERIAL
#include <MySensors.h>
SoftwareSerial swESP(14, 12, false, 256); 
#define MY_RS485_ESPSERIAL swESP

Now what is the output? The serial monitor tells me:

In file included from /Documents/Arduino/libraries/MySensors-development/drivers/AltSoftSerial/AltSoftSerial.cpp:32:0,
                 from /Documents/Arduino/libraries/MySensors-development/MySensors.h:309,
                 from /Documents/Arduino/MotionSensorESP_RS485/MotionSensorESP_RS485.ino:74:

 #error "Please define your board timer and pins"
  ^
exit status 1

Unfortunately I dont know where the AltSoftSerial is chosen. It is not included because of my definitions (as you can see above). So if it is not used, why I need to define boards? Any idea?
Thanks for your help!

Hi,
after getting the prototypes working (I dont know why but the ready to use bricks of max485 are not working, the bare ones do) I like to attach the gateway via ethernet to my controller. I am using the Arduino Ethernet Shield v1 from HanRun HR911105A 16/02.
Unfortunately I dont get any ethernet connection.
This is how I modified my code. Any ideas what went wrong?

Appreciate any suggestions...

Hi PJR,
now it is working with this code in the MyTransportRS485 without any changes on MySensors.h:

#if defined(MY_RS485_SWSERIAL)
SoftwareSerial& _dev = MY_RS485_SWSERIAL;
#elif defined(__linux__)
SerialPort _dev = SerialPort(MY_RS485_HWSERIAL);
#elif defined(MY_RS485_HWSERIAL)
HardwareSerial& _dev = MY_RS485_HWSERIAL;
#else
AltSoftSerial _dev;
#endif

As far as I can interpret the peace of code, the
#include "hal/transport/MyTransportRS485.cpp"
is active as soon as the MY_RS485 layer is defined.

This is a great step, I can use all my nodes from now on!
Thank you very much for your support!
By Kduino

Hi PJR,
thanks a lot! This is obvious. Please apologize that I didn't take a look at this site. So the MyTransportRS485.cpp is loaded only in case of defining MY_HWSERIAL... This explains why it was not working after skipping the MY_HWSERIAL definition.
Unfortunately I was not able to run another test now but I hope it will come up soon.
The changes regarding softwareSerial would be a great help for those who are not able to use the altSoftSerial pins.
Once it is running stable I will post a request @hek to ask for implementation.
I will come back with more tests.
By kduino

PS: It seams that during compilation it loads also the AltSoftSerial.cpp. In case of use of the SoftwareSerial it would be unnecessary overhead, of course. Is there a reason why it is loaded at this stage? I would rather load it at MyTransportXYZ.cpp.

I did it like this:

#if defined(__linux__)
SerialPort _dev = SerialPort(MY_RS485_HWSERIAL);
#elif defined(MY_RS485_SWSERIAL)
SoftwareSerial& _dev = MY_RS485_SWSERIAL;
#elif defined(MY_RS485_HWSERIAL)
HardwareSerial& _dev = MY_RS485_HWSERIAL;
#else
AltSoftSerial _dev;
#endif

The Arduino code is extended by:

// Enable debug prints to serial monitor
#define MY_DEBUG

// Enable RS485 transport layer
#define MY_RS485

// Define this to enables DE-pin management on defined pin
#define MY_RS485_DE_PIN 3

// Set RS485 baud rate to use
#define MY_RS485_BAUD_RATE 9600

// Enable this if RS485 is connected to a hardware serial port
//#define MY_RS485_HWSERIAL Serial1

// Enable this if RS485 is connected to Software Serial port:
#include <SoftwareSerial.h>
SoftwareSerial softSerial(4, 2); //rx, tx
#define MY_RS485_SWSERIAL softSerial

#include <MySensors.h>

Hi PJR,
would you mind explaining me the reason for defining MY_RS485_HWSERIAL?
Thank you,
by kduino

HI PJR,
thank you very much for your reply. I did as you suggested but were not able to test during the last days.
Today I wired it up and it worked. Unfortunately updating some sensor code it is currently not working but as soon as possible I will post the whole sketch together with the adapted MyTransportRS485.ccp.

By kduino

Hi,
I think I got to the specific part of code:

From Github MySensors/hal/transport/MyTransportRS485.cpp
https://github.com/mysensors/MySensors/blob/development/hal/transport/MyTransportRS485.cpp#L88

#if defined(__linux__)
SerialPort _dev = SerialPort(MY_RS485_HWSERIAL);
#elif defined(MY_RS485_HWSERIAL)
HardwareSerial& _dev = MY_RS485_HWSERIAL;
#else
AltSoftSerial _dev;
#endif

But unfortunately I am not able to change it to the softwareSerial option. How would the code look like if I would make an additional if for the softwareSerial?
Help is very appreciated.

By, kduino

Hi Kisse66,

thank you very much for this advice. Most of the forum writers are pointing on the terminating resistors, but in my experience they are not the key.
I put two 680R from B to GND and A to 5V and the reliability I experienced has improved tremendously!
Thank you for the hint.

Another question I have: The gateway is receiving the messages now but there is no ACK. How can I ask for an ack for security relevant messages?

Thank you
By kduino

Hi,
@admins
an advice about the MY_NODE_ID in the how to for the rs485 section would be helpful. I think, there are at least the double of the people trying for hours until they give up. Only some of them take the efforts to register and login here to get useful information...
By kduino

@hek
I used some time to get further. As my tests show I can easily use the Arduino nano on pin 8 and 9, but the strategy of using SoftwareSerial you mentioned is not working.
See what I did below. The problem is now as follows:
If I state the HW_SERIAL command before the inclusion of mysensors.h the hardware serial is somehow not initialized and therefore throws an error on compilation. Only hardware serial ports are allowed.
If I state the HW_SERIAL command after the inclusion of mysensors.h the inlcusion has no effect, thus the defined pins are not rx and tx.
Do you know any advice for that?

Thank you so much for your support!

Hi,
Trank you all for your support. I got in running finally.
I reassembled the complete thing on the breadboard. Then I connected the wires directly (rx-tx and tx-rx). After changing the position of the inclusion of mysensors.h for some times and using the standard pins and the preset node id it worked.
Then I went further to test software serial lib which worked great. Then I extended the model to use the rs485 and after some adaptation of the wires (it's always the wires after some frustrating nights) it worked.
For understanding I integrated also two led to signaling the sending via the de pin. This helped a lot.
As this was working correctly I turned up the speed. Ok, 250.000 bps were too much, but 115.200 were running without any complaints. On a breadboard though but without any cable adaption or resistor as final terminator.
So for this topic we can conclude that if rs485 is not even running on 9600 bps on a breadboard, it's not because of the cable or the terminating resistors. In this setting it should work anyway. Unless you have no bug somewhere else....
So for all my followers again thank you very much. I can only suggest to myself to reassemble the test unit completely to rule out any wrong connections....
Bye kduino

@gohan Thank you, the main message is:
Status: OK (OK=success, NACK=no radio ACK received)
So I have to investigate the RX channel of my node.
By kduino

Hi Kimot,
thank you for your message. I have already built several nodes which don't have the right pinout since I didn't come across mysensors at this time. I asked here in the forum and @hek wrote, I can use SoftwareSerial as well defining it via MY_RS485_HARDWARESERIAL. It will fallback to AltSoftSerial if it doesn't work correctly...
As I mentioned I used this configuration also connecting RX-TX and TX-RX directly and it worked fine. So I assume something is wrong with the RS485 part of my setting. Unfortunately I don't have some Can driver at home.
The DE-Pins are working correctly. Each of them I connected to Led and they are flashing while sending (I assume). So there is somehow a connection, but only in one direction.
My next step is to change the input output pins on the node arduino, sometimes one have bad luck and is struggling for weeks on a problem and the simple result is one burned pin...
Thank you again I keep you updated,
kduino

Hi,
ok I started the next run, I checked the voltage levels (Multimeter is showing a differential of A&B of 0.2 V and is going up during sending.
The Breadboard has no short circuit potential, the wire is now 2x2x0.3 and about 50 cm long, I added R100 to each end...
Then I copied the sketches of the rs485 stresstest posted in the forum...
But it is not working though... ;-(
Any ideas?
Thank you.

Is there any place where I can look up the abbreviations?

@kimot
I started with the examples. Then I introduced soft serial and as far as I consider the direct connection via serial it works. So I checked the de pins, they go active while sending. All good in this part... but together with the max485 the node still doesn't get the gateways response. We will see. Need another evening to try.

For testing I just put the two max485 bricks on a strip board and bridged a->a and b->b, 2-3 cm long jumper wire
I will use a cable instead in the afternoon together with two r100.
I also tested different max bricks to rule out malfunction. Without success.

Hi,
unfortunately it is not working. I have two R200 resistors at the end of my 3 cm long track, I changed the position of MY_NODE_ID...
I will look on the RS485 network closer the next days. Thank you for your help!
Have a nice weekend.

Hi, I tried different Max485 modules but it was just the same. Finally I directly connected the two machines over RX->TX and TX->RX, then it is working fine. So I go in further investigation now where to find the problem on RS485

Hi gohan,
thank you very much, I will check that. The node and gateway are only 5 cm away from each other since I am using a testing area. So no realtime conditions yet. Therefore I didn't use a terminating resistor which is (I thought until now) ok for the length below of some meters...

Hi,
I know here are some who got it working, but there is still some bug for me. Luckily I was able to get it so far, that the gateway is recognizing the messages of the node - but the node don't know it ;-/. It starts the pairing process up and again for endless time...

Please give me the so important hints.

Hi,
actualy I am still struggling getting the rs485 gateway and the motion sensor example running. for some reason they don't communicate. So I connected them directly over serial output without rs485 module - but still no connection. I will investigate further...
As soon as they are connected I will extend the network....

Hi
Before I was able to go testing I was wondering if the gateway would be much easier (but more dirty) to realize with two stacked arduinos. One is operating the rs485 to serial connection and sends it via serial to the second arduino which in turn is connected to udp or http.
I know it would be neater to go with software but as far as I know this is realized within some hours.
By the way in this case it turns into a good platform adapter since the second arduino can be virtually connected to anything.
What do you think?

Have a nice weekend. Kduino

By the way I have done this with the icsc lib from majenko, if anyone is interested. The rs485 input is directly sent via udp and v v.
Additionally I extended the icsc with an ack funtionality to keep track on lost messages on the bus. It runs currently with 57600 baud.

Hi pmeyer,
The node-red stuff seems to be the key for a lot of difficulties in the IofT. There are so many platforms, so many protocols...
As I have a pi around this would be a clever solution. Although a raspi is way too much for this task.
I will try to check it out on the week ends.
A simple rs485 to udp or tcp converter on base of the arduino mega would be nicer though.
Thank you very much!!

Best regards
Kduino

Hi, there is something similar available although without an ac712. So you can't check the percentage o the shutter.
See https://github.com/JanGoe/esp8266-wifi-relay
I had one at home and it is working well. Because of the esp8266 it is directly connected to any controller using udp or MQTT or other protocols.
The only problem is the missing box. I have to admit I wouldn't put this in my wall without a proper box using AC 240 V!!!
The project you proposed is of course the most advanced. Do you think there is a smaller version available perhaps less parts on the BOM and easy to build?
Thank you very much, kduino

Hi,
Thank you very much for the solution @hek: this sounds pretty straightforward and was what I was looking for.
I will check it out this weekend.
It would be fantastic to switch the hole system to mysensors! Since a lot of developing is already done.

I will come back to post my results.

Best regards
Crty

Hi,
first of all thank you very much for the great forum and all the futures built in mySensors!
Although I ve read up and down the forums and information, I am not really clear how to use the SoftwareSerial instead of AltSoftSerial lib. There are some comparison why the one might be better than the other but I didn't grab a sketch sample to go from there.
The reason why I am asking is that I had established an rs485 network with custom designed nodes on arduino nano with rs485 shield. The system is a little bit like mySensors, it works with the ICSC lib, but unfortunately I came across mySensors too late. So all my PCBs are done and the parts are soldered and the rs485 module is connected like this:
DI = Pin 2
DE/RE = Pin 3
RO = Pin 4
The only option I have now to "upgrade" to my sensors is to get the SoftwareSerial lib running.
Time is not an issue for me, so it would be totally sufficient to run at a speed of 19200 or 57600 Bauds.

Is there anyone with a similar problem giving me a hint how to get along with it? That would be very nice.
Best regards,
City

Hi Florian,
These inputs I would love to use.
Therefore I need a gateway which transforms my rs485 network to an udp message. I solved this by the Icsc lib and an arduino uno with an Ethernet shield. However, it would be much more fun to use the mySensors code which is much better and has more opportunities
The only thing I am wondering is after reading up and down: how to set the gateway to rs485 and (!) udp?
I found an example for udp and one for rs485 but not the combination. I think the rs485 network hands over serial messages via usb?
Would be nice to see a starting point, do you have an idea?
Thank you so much!

Kduino

Hi,
I am wondering if I can just use the mySensors Lib to pass on the data via another connection. Currently I have a Loxone Controller which accepts UDP and TCP/IP connections (and others, but I chose these). As gateway I have an ArduinoMega and the network is running on RS485.
So my understanding is that I can setup the network with the mySensors code and all the data is collected by the gateway which passes the data via UDP to the controller. V.v. the controller sends the data to the gateway which passes tha data on to the correspondent node.
Is there any project similar to this?
Thank you very much for your help!
Best regards Kduino

Hi there,
I just started with an arduino rs485 network and chose the Loxone Miniserver air controller which is really nice except it's Windows dependent config software.
Since I am already in the topic I was wondering if someone had a similar approach. I would love to connect the rs485 gateway to the mini server by udp or TCP/IP.
Any ideas? Any experience?
Thank you very much,

Kduino
