    • RE: Battery level swings

      I did have the battery check happening just before going into sleep mode, so I guess it makes sense that in some cases the battery would be low and trying to recover. I'm assuming the peaks I was seeing could have resulted from when sensors were checked and there was no change in value and so no transmit which would have left the battery with more juice.

      I've moved my battery check routine to be the first thing in the loop and I'll see how it goes.

      @Anticimex, your point about tuning the algorithm is a good one because I've been using NiMh batteries to power the system which are topping out at about 2.8V when fully charged, and the booster is supposed to work down to 0.8V, so I'd like to realign the range for the reporting to fit this. Any suggestions on the best way to do this?

    • Battery level swings

      I'm currently working on building a sensor with a DHT-11, Dallas temperature sensor and a door switch. Currently everything is running from 2AA batteries which run through a booster. I've been monitoring the battery voltage being reported after adding in the voltage divider according to the build instructions and I am seeing swings of about 5-10% reported in the battery level between readings. Just wondering if this was typical, or if there is something I should be looking at? I've tried with and without the capacitor on R2 of the voltage divider. I'm taking the reading from the batteries by tying into the VIN pin on the regulator then through the voltage divider.

      Any guidance would be appreciated. Thanks!

    • RE: MySensors 1.4 Released

      @hek I did some testing and it appeared to be a sync issue. First I looked at the gateway and the debug messages showed Imperial units which matched the Vera UI. Then I unplugged the temp. sensor from power and plugged it into my laptop and it was reporting Metric units in the debug, and then Vera started showing Metric. So I unplugged the sensor from my laptop, plugged it back into it's original location and the units switched back to Imperial. Finally I just rebooted the gateway and the sensor and now Metric is working.

      Anyway, thanks for your help!

      @TroyF

      You followed the download link for 1.4 on the main site?

      Hi Hek,

      Yeah from the main page, I went to the Download page and then hit the Download button under the 1.4 Latest Release section. The readme file in the archive says 1.4, but I'm looking for 1.4 Update 1 which has the fixes for the imperial vs. metric units with temperature sensors. I rebuilt my gateway with the code anyway but no change. Am I missing something?

      Thanks,
      Troy.

    • RE: MySensors 1.4 Released

      @hek Can you help me to understand how to get the update, and what parts are updated? I followed the download link to the library and installed the files. I then updated my gateway but I didn't see any version number change and I'm still having trouble with temperature readings coming through in Imperial units rather than metric.

      Thanks, and keep up the great work!

      Troy.

    • RE: Arduino Nano Gateway for Vera - PCB link

      Ok so.... things not to do:

      1. Don't short the holes for the capacitor.

      When I thought about this some more I realize it didn't make any sense to do that. I clipped the short and presto the Nano booted properly, no solid TX RX. So I cleaned the holes and put the capacitor in just for kicks and I think everything is working now.

      A big thanks to Ross for putting the PCB together it's awesome!

    • RE: Arduino Nano Gateway for Vera - PCB link

      So I ordered a batch of these from OSHPark and they arrived a couple weeks ago. I've put one together but I'm running into a bit of a problem. Let me start by saying it's almost certainly me. I'm sure the boards and the design are fine. I'm pretty confident the Nano and the radio are fine too because they were working fine on a breadboard.

      So when I plug everything together on the PCB the TX and RX and Power lights on the Nano are on solid and stay that way. The middle LED on the PCB gives a brief flash and that's it, nothing else is happening. If I take the Nano out from the board it seems to boot up normally.

      So I've looked at my solder job and while not great I don't see any shorts, but I don't quite understand why the TX and RX lights stay solid when connected. If I connect the Nano to my laptop when plugged into the board it doesn't recognize a COM port.

      Now I should admit that I did not put to capacitor for the radio onto the board, I just shorted the holes. I wanted to try it first without the cap. because I hadn't needed it on the breadboard. My brain tells me this shouldn't be causing a problem, but maybe it is?

      Any suggestions that anyone would have for me to check would be awesome.

      Thanks!

    • Why does MySensors setup both a Node device and Temperature device in Vera?

      As I am beginning my journey with MySensors, I wondered if anyone could explain to me what the design decision was around having two separate devices created in Vera for each sensor? In my case adding a temperature sensor created two devices, a 'Node' device and a 'Temperature' device. I'm just curious to understand why these needed to be created as two separate devices instead of one combined device?

      Thanks,
      Troy.

    • RE: Issue with temperature units

      Strange. I actually just left it alone and a few hours later it was reading in Celsius like it should have been. Not sure why it took a while to start reading that way, but it's fine now. Thanks to everyone for their responses.

    • Issue with temperature units

      Hello everyone,

      I'm just starting out with MySensors, but think it's just amazing. Thanks to Hek and everyone else who has contributed for putting this together. I recently tried to setup a v1.4 serial gateway and a simple temperature sensor but for some reason I'm having trouble with the temperature reporting back to imperial, despite Metric being selected in the gateway device within Vera. I've tried toggling the switch back and forth, restarting Vera etc., but the temperature keeps being reported in Fahrenheit. Does anyone have any suggestions?

      Thanks,
      Troy.
