      @mfalkvidd thank you very much for your quick answer! I'll look into that.

      @Yveaux said in serial, Ethernet to MQTT: Of course, but MySensors MQTT gateway runs just as fine when connected over cabled ethernet, as when connected over wifi I do not know that Now on this tool, I do not see much benefit from ethernet to MQTT Still, it is good from serial to MQTT.

      @NeverDie said in LCDUINO: the LCD components don't appear to be named, not even on the schematic Looks like a typical text LCD like 1602 on the picture.

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

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

      Seems the original uploader does not seem to he on the forums anymore. The BOM in wrong - the 74LVC245 needs to be a SOIC-20 not a TSSOP-20.

      @shabba The majority of the components are 0603 SMD package type (except 2 smd resistors on the usb lines which are not really mandatory and can be replaced with a solder bridge). There you go (extracted from schematic - I can't do better than this because it involves more work and I don't have time for it, sorry): a) 9 x 100nF 0603 SMD MLCC capacitors, X5R/X7R (voltage can be 10V and above) b) 3 x 1uF 0603 SMD MLCC capacitors, X5R/X7R (voltage can be 10V and above) c) 1 x 10uF 0603 SMD MLCC capacitor, X5R/X7R (voltage can be 10V and above) d) 1 x 22uF 0603 SMD MLCC capacitor, X5R/X7R (voltage can be 10V and above) e) 1 x 10nF 0603 SMD MLCC capacitor, X5R/X7R (voltage can be 10V and above) f) 1 x ferrite bead 0603 SMD blm18he152sn1d g) 3 x 330 ohm 0603 SMD resistor h) 1 x 1Kohm 0603 SMD resistor i) 1 x 10Kohm 0603 SMD resistor j) 1 x 56Kohm 0603 SMD resistor k) 1 x MCP1703A-3302 3.3V/0.25A voltage regulator l) 1 x TXB0104 voltage level converter m) 1 x ATMEGA328P-MU AVR MCU (QFN32 package) n) 1 x CP2102 USB to serial (QFN28 package) o) 3 x 0603 SMD LEDs (your pick here) p) 1 x ATSHA204A (SOT-23 package) q) 1 x RFM69W module (your pick regarding working frequency) r) 1 x ZTTCS16.00MX ceramic resonator s) 1 x USB A type male connector for PCB and 1 SMD reset switch (I have no exact links for this, sorry)

      Actually, I use the FTDI connector on my outdoor weather sensor to power it from the solar/Li-Ion charger board. Used angled headers to keep the height down. I'll try to post a picture asap.

      @tbowmo more out of curiosity, and from someone that just got started on electronics, so please sorry if this sounds like very noob, but, would it not be safer to plug the V_TARGET LED to the +3.3v pin? How do you ensure that the resistor on the V_TARGET will have constant voltage and that will not blow from over voltage if the VCCio pin is depended on the the Motherboard power? Thank You and nice work

      @marceltrapman when you change the BAUD rate setting in the source/config file to something lower/other you can also use 3.3V Arduinos as (Serial)Gateway. Of cause your controller needs also to be told about the lower BAUD rate. Check out http://wormfood.net/avrbaudcalc.php?postbitrate=9600&postclock=8 for an overview of Clockspeeds (usually 8MHz for 3.3V and 16MHz for 5V types) and coresponding BAUD rates.

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

      C.r.a.z.y.

      @celonunes generally raspberry pi with serial usb but also you can see some mqtt logs. Same problem with mac os with serial usb. I also tried rpi uart pins for serial bu there is no logs for it. Maybe someone gives his Openhab dir i can understand better problem isnt related with hardware

      @brettzky84 said: Im using the serial gateway on u17 and have it working fine. i have the same problem as you when my vera is rebooted or powered off, but found 2 solutions. 1 with the vera on disconnect then reconnect the serial gateway. wait 10seconds refresh the dashboard page. Then go to app/ developer apps/ serial connection. Reset your baud rate to 115200??... Thansk. I ended up upgrading to the latst UI7 beta. My gateway is now working!!! Let's see how stable it is. (UI7 has fixed some of my other issue too)

      You are right, that is a possible solution for my problem. I think changing software should be favoured over changing hardware.

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

      Thanks for all the info all But still have the problem with vera3 on ui7 Cribben, I follow the instructions on the my sensor vera plugin and it comes up with ver 1.3 and no lib # how did you get the new plugin to load Any help at all would be welcome as ui7 is not too smooth yet.
