    • RE: 💬 Building a Raspberry Pi Gateway

      @mfalkvidd thanks, I was wrongly under the impression that sudo mysgw would show the logs but it creates a second instance. Thanks for helping 😄!

    • RE: Advise - Building air quality sensors/network

      @nca78 appreciate the elaborate answer, thanks!
      Regarding NDIR sensors, how frequent do they need to be recalibrated to maintain accuracy?

    • RE: 💬 Battery Powered Sensors

      @sineverba thanks, I got it working and it's up and running. Still have to desolder the led and remove the regulator, will do that later.
      Regarding the BOD, what happens if I disable it? Will it run for longer as it does not shutdown? Or is any voltage below 1.8v bad for the arduino?

      A bit off topic maybe, but I was wondering how the 'pros' around here make the sensor small and sturdy for Arduino's with Si7021+ 2xAA battery pack. My DuPont wires seem a bit loose, so I'm wondering whether I should solder them. And perhaps someone 3d printed a case for an Arduino+Batterypack or some sorts.

    • RE: Error when trying to use another library with mysensors

      @krabbi I have a similar issue as un4 described.
      When nWake is connected on GND it works fine, when connecting to D3 (6) it stops working. I'm using the same sketch source as krabbi. Any suggestions?

    • RE: V_UNIT_PREFIX not working/recognised for Air Quality sensor CSS811

      @niclas hey man it seems to be working due to putting the version in the config file, at the right indent. So your suggestion worked after all, guess I had to wait a bit before it was recognised by HA. Thnx, problem solved 😃

    • Battery powered Pro Mini - Si7021 loses connection with gateway after ~6hrs

      Hi all,

      I'm running a Pro Mini on 1Mhz with a Si7021 sensor on 2x AA NiMh batteries (~3.6V). It all works fine for around 6hrs before it loses connection with the gateway it seems. It doesn't update anymore which results in a flatline in Home Assitant. Upon pressing the physical reset button on the Pro Mini everything goes back to normal; Temp/Hum are reported accurately every minute. The mysgw.log does not show anything strange, it just stops showing data from the specific node. I ran the Pro Mini on a steady 5V input which resulted in the exact same behaviour. Other than changing the freq. the hardware of the Pro Mini remains unchanged.

      What can be the problem? How can I make sure it doesn't lose connection.

    • RE: 💬 Battery Powered Sensors

      @Puneit-Thukral Will do!
      After closer inspection the pins of the NodeMCU seem to be a lot bigger in size. However I am struggling to find the correct sizing of Arduino Pro Mini pins (width/thickness). The spacing between pins and length of them are easy to find but I cannot find the thickness at all. Do you have an idea?

    • RE: 💬 Battery Powered Sensors

      @Puneit-Thukral cool, from what I read the pins are the same size as on Arduino's. I'll use this design to create one for myself.

      @Puneit-Thukral in your screen it shows a number right?

      edit: is there a method to resize uploaded pictures here?

    • RE: 💬 Battery Powered Sensors

      @Puneit-Thukral haha okay I see.

      Another question, your case that you use in the video snaps onto the pins perfectly it seems. Did you 3d print that yourself? I'm looking to 3D print a case for my pro mini and some other sensors that snaps in a similar way so that nothing moves around. However I'd rather copy a proven design than figuring out the tolerances myself.

    • RE: 💬 Battery Powered Sensors

      @Puneit-Thukral interesting! Seems as a better option than Dupont, I'm gonna look into it.
      You mention hot glueing the wires yourself as extra protection. But I imagine you can also put a layer of solder on it right?

    • RE: 💬 Battery Powered Sensors

      @mfalkvidd thanks makes sense, eventually I will switch to NiMh. Had a look at the different cases, gives some good inspiration thanks for pointing in the right direction!

      Now that I want to desolder the regulator and LED on the Nano, I just want to verify something, since the video shown is about the mini pro.

      (1) Is the circled part in the image below, indeed the regulator on the Nano?
      (2) On the battery powered sensor page, step 4 states to cutout the Vout pin. Why does this lower power consumption, and how can I locate this on the Nano?
