    • RE: Clean looking sensor node

      @Nca78 said:

      such a polished look

      Actually it can have that look if you print with ABS and treat it with acetone vapor afterwards.
      For example look at these pictures

      Have treated my prints that way many times and the result is very good.

    • RE: Read LED full size works, smd does not

      Found the problem myself ๐Ÿ™‚
      There was another resistor on the other side of the PCB. If I connect the cable there instead it works

    • Nice power regulator for testing

      I bought a couple of these to test and they are working great.
      If supplied with 12V you will have 3.3V, 5V and 12V

      They are limited to 800mA

    • RE: Getting started

      @vizonyc
      I think I have the setup you like to have.

      Running Openhab with mosquitto on a virtual server.The openhab uses KNX, 1Wire, sonos and MQTT bindings.

      My Z-Wave devices is connected to a Raspberry with the Z-Wave board Razberry that uses MQTT to communicate with openhab.

      Finally the connection to Mysensors is done with the GatewayW5100MQTTClient and is user for example like "Temp Gรคststugan" that shows the temperature in the guesthouse.

      I do not have any relays in the mysensors network yet, but I have them in my Z-wave network and communicate thru MQTT to the Razberry

      On top of that Im running Dashing Dashing

      So we have dashing on a tablet inside the door that displays all info and we can interact with all systems(KNX, Z-Wave, 1-Wire, Mysensors) from one place. We have also added things like when the next bus is leaving and so on.
      dashing

      And it's working great. So if you have any questians please let me now so can we see if I can help you set it up

    • RE: Easy/Newbie PCB for MySensors

      Recived my boards today and I love them, I ordered the white ones and they are looking really great

      Thanks @sundberg84 !

    • RE: Office plant monitoring

      It seems like @sundberg84 nailed it ๐Ÿ™‚
      The battey metering I use with his PCB is this:

      #if defined(__AVR_ATmega2560__)
        analogReference(INTERNAL1V1);
      #else
        analogReference(INTERNAL);
      #endif
      

      And that reflect on all analog channels and break the function..
      After I removed the battery sensing code it work great

    • Add a structure level under My Project?

      Not so much a request as wishing.

      Would it be possible to add a structure under My Project to collect all the SenseBender, Slim Node projects, Easy/Newbie PCB and so on so it would be simpler to find?

      A structure like this for example:
      My Project
      ย  ย  SenseBender
      ย  ย  Slim Node
      ย  ย  Easy/Newbie PCB

      Or to pin a topic for containing links to all projects

      This maybe already been up for discussion ?

    • RE: PowerSaving cutting

      Thank you, I try that first.
      I cut the red LED and let the blue one be (since it just blinks a couple of times when starting up)

    • RE: ๐Ÿ’ฌ Building a MQTT Gateway

      @DIM said:

      my ignorance but I would like to k

      The gateway is a arduino with NRF24L01+ (or RFM69) and serial/network/RS485 component. The sensor is another arduino with NRF24L01+ (or RFM69) and the sensor that are attached. The gateway is then acting as a translator from the NRF24L01+ (or RFM69) radiosignal to the medium that can talk to your controller

    • RE: Battery powered sensor last 1 week

      @scalz

      Or just simply take percentage and date/time and then a few days later see what has changed percentage wise ...
      Its to simple I know but if 1% battery power equals 4 days the sensor probably last for about 9-10 month (the last percentage I suppose you don't get any communication with ๐Ÿ™‚ )

      @sundberg84 Hmm What you are saying is that I need to buy a new and better Multimeter ๐Ÿ™‚ This is the reason I was waiting for ..... :9

    • RE: ESP8266 need six analog input

      @mfalkvidd

      Tnaks,
      I saw that Adafruit had a library and code or this that should be ESP8266 certified ...

      I'll try. Thanks for quick support
