    Hi2All! Surprising is here. After about 24hours I refresh HA and suddenly my motion sensor was integrated. There is also second entity > battery : 0 , have to look deeper into that for understanding. Need to change little in the sketch, because don't want every short time 'no movement' so only when there is motion and maybe once a hour indication sensor is alive. Meantime I found 3 other good threats: https://forum.mysensors.org/topic/11200/finally-progress-evidence-based-radio-testing-method-and-capacitors https://forum.mysensors.org/topic/1664/which-are-the-best-nrf24l01-modules/27 https://forum.mysensors.org/topic/9550/build-a-reliable-power-supply-chain Very usefull for me also finally progress because of lacking time in the past. Great jobs are done here! Thanks for this all of you guys or girls!

    Node to node comunication with optional controller

    i think i finally get it. It is impossible... well the only way to let nodes communicate with each other is when a gateway is available (directly or trough other nodes) when the node is starting up. This forum discussion is explaining me the most.. a solution may be.. transform the node that is always on to an gateway. And use antoher channel.. Sidenode; then you can't tell the controller what the status is. Is there realy no way that this can supported? Node to node comunication without the need of an gateway inside the network? Skipping the registration and just send the message around. perhaps i will dive into the source one day and change the registration behavior. Thanks anyway for the help and the very fast responding.

    @zamorae great to see that MySensors seems to be a good fit. Welcome to the community :) MySensors is available with two licenses: GPLv2 and commercial. GPLv2 basically means you can use it for free as long as any code you develop is also made available for free. This means everyone benefits from improvements made by everyone. If you want to keep a commercial solution "secret" you can buy the commercial license. Some details are available at https://www.mysensors.org/about/mysensors#copyright

    how to ask a node to re-send presentation info

    thanks, it works - in principle! I'm using smartSleep in my sketches and that causes the nodes to send heartbeat signals, which is o.k. But can it be, that the request for presentation is only received and responded to by the nodes when the node has sent a heartbeat? When I receive a regular sensor reading and fire back a presentation request, the node doesn't seem to care...?!

    Hi, I haven't found any specific documentation but looking in the MYSBootloader's code I found this two checks in HW.h (https://github.com/mysensors/MySensorsBootloaderRF24/blob/development/HW.h) #if defined(SPI_PINS_CE9_CSN10) .. #elif defined(SPI_PINS_CSN7_CE8) .. #endif does it mean that those PINs (9+10 or 7+8) are the only options to have MYSBootloader on Arduino boards? (obviously without modifying the code and recompiling..) thanks Max

    Thank you all. I changed the register values directly in the RFM69 driver and it all seems to work. Hopefully a new release will soon include this (as well as the ATC feature). Also, local legislation specifies maximum transmission power as 10mW for the 433 band, so I included the code below in my sketch. It would be good to be able to configure this in the future as well. #ifdef MY_IS_RFM69HW _radio.setPowerLevel(16); // 10dBm for RFM69HW #else _radio.setPowerLevel(28); // 10dBm for RFM69W #endif

    @AWI Darn you are right!!!!! Thanks! Have been dealing with rpi and upwards lately so assumed it has some kind of internal clock. Thanks again!

    @mortommy YES !!! That's it !!! But it is fatal error , because i use step up booster and when battery goes down , It caused that arduino start / shutdown quickly , it spams my Gateway I must disconnect it .

    I'm also interested in Ethernet Gateway with RS485 transport. At the moment I have successfully tested this on Arduino UNO with 2 different Ethernet modules, W5100 and ENC28J60. In both cases I'm using hardware serial port on Arduino, not AltSoftSerial. // Enable this if RS485 is connected to a hardware serial port #define MY_RS485_HWSERIAL Serial

    @alowhum They seem to be not quite as easy for copy paste programming. I have had to do a heap of reading and learning to get it all down. Any the other one is you search the forums for soloutions before posting and half the solutions are pre 2.x and dont work either, I don't like noob posting basic stuff due to my lack of programming skill, but people here seem quite nice and willing to help :) Wait for my debouncing post later tonight if I cant work it out hahaha

    I completely agree. I am having a hell of a time getting mine to work at its to the point where I'm searching for an alternative to mysensors. This post should be in the main page regarding setup. I have wasted hours trying to figure this out.

    @Søren-Heide-Larsen different networks can be achieved by setting different channels / network ID. See here for NRF24 and here for RFM69. There is no pairing function in MySensors.

    Great ! Now I have to implement a circular buffer and the solution will be perfect ! Edit : This reading is interresting : http://hackaday.com/2011/05/16/destroying-an-arduinos-eeprom/ The user did a test to wear out EEPROM, and did managed to get more than 1M writes before it started to fail !

    Sensor IDs, best practices?

    @napo7 said in Sensor IDs, best practices?: This way, I can keep AUTO ID feature, the controller always give me new ID when needed, and I can easily replace a failing node with the same board, just changing his ID after uploading his firmware ! But when your controller/plugin/binding 'remembers' the id's it assigned you will end up with id's assigned without a sensor attached.
