    • My very first mysensors node!

      Hi!

      I'm starting my home automation journey and the architecture will be autonomous mysensors-nodes also controlled by Home Assistant.
      Maybe some sonoff's for some special needs.

      My house has 3 floors and the middle floor is 100% renovated 5 years ago so there I have to make compromises but the other two floors we are renovating and also recabling all the electrics so it's easy to get all cables routed to a central place for automation control.

      I already have Home Assistant running a few months and its collecting sensor data from my geothermal heat pump, UPS device and some software running on my home server.

      This first node is a kind on POC and wife approval node. It goes to a hallway in my basement which we are renovating at the moment.
      The node has:

      • 5V power from the AIO (maybe I'll need a fuse? or this https://www.openhardware.io/view/504/HLK-PM01-breakout-board)
      • Arduino Pro Mini 5V for the brains
      • NRF24 radio
      • DHT22 for temperature and humidity
      • A relay to control lights
      • Standard Finnish light switch (existing one)
      • Hall sensor for laundry room door

      The idea is to make the system fault tolerant and not dependant of Home Assistant which I have to update from time to time and which runs on RPi3 which can fail.

      Other nodes I'm planning:

      • Water pump monitoring and control
      • Electricity monitor
      • Freezer monitoring
      • Laundry room machines monitoring
      • Lights inside and outside of the house
      • Temperature sensors to all rooms
      • Control of under-floor heating valves (21 at the moment)

    • RE: Arduino UNO ethernet gateway problem

      Evening!
      Happy to report that soldering the two resistors to the back fixed the problem!
      So no need to downgrade Arduino IDE etc..

      Hi!

      Investigating this issue it seems that my chinese ethernet shield has the wrong kind of terminating resistors on the ethernet line as described here.
      So first I'll try to apply the common fix for that problem (change the resistors) and then I'll get back to you.

      Btw thanks for the awesome support!

      Hi!

      Sure. Here is the link: https://forum.arduino.cc/index.php?topic=351477.15

      There are many options for the fix but the easiest is defined by klggi on page2 (just solder 2 100ohm resistors on the backside of the ethernet connector).
      I'll try to apply this fix tomorrow evening, I'll get back to you on how it went.

      @gohan check the post by klggi. No need to touch the SMD's, just solder 2 regular resistors to the backside of the connector.

      I used just regular 100Ohm resistors like this 0_1490677932738_img.jpg
