    • MySensorsNode (MSN) All-In-One-PCB for easy node building

      Hi
      I made a universal device for mysensors to building easy different nodes. The PCB fits in a small case (Strapubox 6090), so simple sensors can build with minimal effort.
      alt text
      The minimal assembly consists of a Mega328P microcontroller (as seen on many Arduinos), a RFM69CW rf module with 868 or 433 MHz and some little stuff for reverse protection and battery monitoring.

      With different assembly options, this PCB can be used for:

      • Temperature, humidity and pressure measurements (With BME280 assembled)
      • Temp-Sensor above with additional light level (with extra BH1750 on the proto field)
      • Cheap temperature measurement (With DS18B20 assembled on the small proto field)
      • IR-reader for digital Power meter (with external IR Head connected to the UART)
      • Prototyping on Breadboards with soldered pin header

      The PCB features also

      • ISP pins are connected to the pin header for easy flashing the bootloader
      • Arduino pro mini compatible pin header for connecting a cheap USB-UART-board without wires
      • Optional LED (for example for active transmission)
      • Mounting holes for fitting in the “Strapubox 6090” case
      • A snap off proto board, which fit under or on top of the MSN PCB.

      Hardware and software can be found on my github repository. Github/se-O-matic/msn/

    • RE: HassOS + Serial Gateway OR Docker + RPI Ethernet Gateway

      Thanks for the answers. 🙂

      I want to keep the raspberry pi as central. This should fit all my needs in my rental apartment.
      For HA, I have chosen a SD-card with application class A2.

      For a clean setup, i will try to run HA in docker. So can i use the same Raspberry as gateway and for the controller.
      So I dont have to use a "rare" mega328p for a serial gateway.

      I report my results, when I find some time to work on it.

    • RE: HassOS + Serial Gateway OR Docker + RPI Ethernet Gateway

      Hello,

      finally, ... I had time to test the "Option 2".
      Because the stock of all shops are empty, I used my old RPI 3 B+. But after all, the CPU runs at 50%. Even the 1 GB ram is half free.

      The way wasn't as easy as I thought. But now the setup runs pretty good.
      This steps I had to make:

      1. A fresh install of Raspian Lite (I used 64-Bit, if this is needed? I dont know)
      2. Installed "Home Assistant Supervised", which runs in a docker. (I found a tutorial based on this informations: https://github.com/home-assistant/supervised-installer)
      3. Installed the MySensors Gateway with some changes! (https://www.mysensors.org/build/raspberry)
        3b. The manual works fine for 32 Bit raspbian. For 64 Bit you have to edit two files bevor the compile starts. (https://forum.mysensors.org/topic/11456/is-mysensors-rpi-gw-32bit-only/8)
        In my case i have to change the section for the BCM2837 (= RPI3) as described in the post.

      Now, I have a clean setup for my smarthome with MySensors Nodes and Zigbee Nodes.

      The RFM69 ist directly connected to the GPIO of the PI.

      The power consumption is araound 2 W. Somewhat lower when idle.

    • HassOS + Serial Gateway OR Docker + RPI Ethernet Gateway

      Hi,

      currently I'm using MySensors RPI-Gateway and MyController on the same RPI 2 .
      I connected a RFM69 Modul directly to the GPIO of the Pi.
      This system works fine for many Years.

      Now its time for an upgrade.
      I want to use HA and I want to add ZigBee devices. For that I purchased the SonOff Dongle-P and I grapped a RPI 3 for testing HA parallel to my running setup.

      Now I want to tidy up. Two RPI for a task, which one alone can do is not the best solution.
      The question of all questions is now, how to combine HA, MySensors and Zigbee in the best way?

      Option 1 (I have to build the serial GW, and ICs (328P) are rare at the moment):
      HassOS + MySensors Serial Gateway (RFM69 connected to an ATMEGA328 connected to the UART-pins from the RPI) + ZigBee USB Stick. (I dont want to use a UART<-> USB chip, when a RPI has native UART on the GPIO)

      Option 2 (Favorite, because I dont have to build hardware stuff):
      HA running in Docker + MySensors RPI Gatway (RFM69 connected directly to the GPIO) + ZigBee USB Stick. (I found a tutorial for installing HA in Docker with Supervisor)

      Are there any pitfalls in the Options above?
      Can I use the UART Port "/dev/ttyAMA0" in HassOS?
      Are there any limitations in Option2, when HA running in Docker?

      I hope someone can give some tips.

      Thanks!
      Sebastian
