    • RE: 💬 MySensors ESP8266 MQTT gateway

      Hey @ejlane! Many thanks. I didn't see your message from a while ago (don't seem to get these in my email). I just ordered the PCB at JLCPCB.com. Worked great! Thanks again. Looking forward to building this gateway.

    • RE: 💬 MySensors ESP8266 MQTT gateway

      Hi Japio, I would like to build this gateway. Where can I have the PCB printed? I tried dirtypcbs.com but it reports some files missing and I would have to order 10 pieces. Can you make me a recommendation? I live in the Netherlands. Thanks in advance! Cheers, Roland.

    • RE: Error compiling gateway for esp8266 node mcu(1.0) e12

      @Bramz Hi, have you been able to compile the MySensors NodeManager for this ESP2866 board? I'm having similar problems. I'm now using Arduino IDE 1.8.12, MySensors 2.3.2, NodeManager 1.8. I've tried several versions of the ESP8266 library, but I get different errors with all of them. Have you been able to find a combination that compiles? Thanks in advance.

    • RE: Solar powered sensor board

      @Yveaux Thanks for your response. I guess that's it. I have to burn a bootloader first :-). I have a USBasp Programmer for that. Can you point me to a wiring diagram that shows how to connect the programmer to the circuit board?

    • RE: Solar powered sensor board

      Hi Guys,

      I also bought two of these boards a while ago. I have the NRF, a BH1750 sensor, and cables for battery and solar panel soldered to the board. I'm now trying to upload the sample code to the board. I have the board connected to my Mac as usual through an FTDI adapter. I'm running Arduino 1.8.6. The code compiles fine but cannot upload to the board. The following error is produced:

      "Sketch uses 4266 bytes (13%) of program storage space. Maximum is 30720 bytes.
      Global variables use 312 bytes (15%) of dynamic memory, leaving 1736 bytes for local variables. Maximum is 2048 bytes.
      avrdude: stk500_recv(): programmer is not responding
      avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x00
      avrdude: stk500_recv(): programmer is not responding"

      I guess the board does not get in flash mode... Settings I use in Arduino are:

      Board: Arduino Pro of Pro Mini
      Processor: "ATMega328 P (3,3V, 8 MHz)

      Any ideas what is going wrong? I would love to see some examples of how the board is used. I want to use it to drive a relay that turns on my DMX controlled lights in my shed. Adding a temp/humidity, motion, and perhaps smoke sensor would be nice too.

      Hope you can help me move forward. Cheers, Roland.
