    • RE: openHAB binding

      Hello all,

      i use a ATMEGA328P with internal clock (MysBootloader) and have a 4-channel relay board connected at the Arduino outputs D3-D6 (current MySensors Example Sketch).

      As central unit i use a RaspberryPi with openhab 1.8 and a serial gateway (Arduino Nano) and the MySensors- OpenHAB serial binding of @bkl

      The OpenHab item looks like this:

      Switch Lights_Downlights_Front "Downlights Front" <selfLight> (Outdoor, Lights_Outdoor) {mysensors="54;1;V_STATUS"}

      Unfortunately I can not switch the relays ON or OFF.
      Many other sensors (Temp, Hum, Rain) works fine with this environment.

      Any help is appreciated!

      Greets & Thanks

    • RE: Yet another mailbox

      @mbj No hurry, at the moment i´m waiting for parts from HK and can´t do anything until they arrive.
      I communicate with an MQTT Gateway (Arduino Nano/ W5100/ NRF24l01) and MQTT binding (1.8.0) between the MySensor items and OpenHab (1.8.0).
      I will build some sensors like described in this thread http://forum.mysensors.org/topic/2067/my-slim-2aa-battery-node
      One of them will be a mailbox sensor with your sketch...

    • RE: Yet another mailbox

      Very nice project, i would also like to build this mailbox sensor.
      Could you please share the modified sketch and the tweaks for openhab... ?
      Thanks in advance

    • RE: My Slim 2AA Battery Node

      @ahmedadelhosni and @BartE and @m26872 you made my day...!
      Changing the NRF module was the solution, now my power consumption is about 8uA.
      Now waiting for the PCBs and parts to build 10- 15 nodes

      Thank you so much for your help

      @m26872
      I have already tested the "reed switch sensor" and it works fine for me- but with a power consumption of 2mA ...:-(
      Is it possible that i have a problem with the bootloader or the fuses ?
      How can i check that ?
      Usually i use USBASP and avrdude for programming the processors on breadboards.
      Is it also possible to do the whole programming with the arduino IDE ?

      @AWI

      No FTDI Adapter, no LED and nothing else is connected.
      I build the node like the schematic in the first post.
      When i start the sensor node, power consumption is about 16mA.
      After a few seconds (4-5sec) the current goes down to 2mA

      Can you please tell me, how to find out, that the node is in sleep mode
      I have really no idea how to fix that.. but i have to, because i ordered the PCBs today!

      Thanks for your help

    • RE: My Slim 2AA Battery Node

      Hello m26872,
      your project is great, and i will order tomorrow a set of PCBs.
      I've done a breadboard setup with the SI7021 according to your schematic and your sketch, which works flawlessly.
      (ATmega328P / SI7021 / NRF24L01 / 2xAA Battery / your 1Mhz bootloader / your Fuse Settings)

      Unfortunately I do not get the current consumption below 2mA.
      What to do to get the power consumption below 10uA and to increase the battery life on a couple of years ?
      Any help is appreciated...
