    • RE: [SOLVED] After upgrade to mysensors 2.1 problems with radio module might manifest itself more.

      @Anticimex and @tekka .
      I just upgraded my GW (MEGA) and most sensors.
      I do not know what you did, but my range is incredible now (and everything works!)
      I had good coverage in my apartment before, but if I went outside my front door it started failing (steel security door).
      Now, I can not only go outside the door, I can actually go 3 stairs down in my building with AWIs NRF tester.
      Same hardware is used and nothing has changed from my part.

      Kudos and thank you.

    • RE: gw.sleep on battery powered magnet door switch

      @siod , I had the same problem.
      I actually ordered a original NRF 24 mini and this seemed to solve some of my problems.
      i think another problem I'm having is that my batteries has a huge self discharge (old 3.7v 18650)

      On a side note.. I'm with @sling .
      Loose the pullups and set them LOWยด.
      I have a 1MOhm resistor between VCC and PIN 2 and PIN 3 (also 2 switches).
      Using the pullup HIGH draws around 130uA versus LOW it draws between 7 to 10uA!

    • RE: ๐Ÿ’ฌ Battery Powered Sensors

      @mfalkvidd , it was too late at night for me.
      I had it at current but it didn't show anything. So without thinking I put it at voltage.
      And the problem with not showing anything when I had it at current was I had blown the internal multimeter fuse some days ago.
      Ehrmm.. yes. move along, nothing to see here ๐Ÿ™‚

      And also, @m26872 , the node 105. Is it alive?

      @parachutesj you have to modify the pro mini. Remove the power led according to instructions!

    • Watering flowers on the balcony + LED illumination

      I recently managed to build a small irrigation system for my balcony, using mysensors of course!
      It was picked up by Sweden's best "smart home"-shop "m.nu" and I had a chance to blog about it.
      @hek , I didn't really clean up the code so you actually got credit for it on their facebook page, lol.
      Hope you approve or I will make them change it.
      Maybe you can see a trade off with the fame and that I also mentioned mysensors.org ๐Ÿ™‚

    • RE: [SOLVED] After upgrade to mysensors 2.1 problems with radio module might manifest itself more.

      @Anticimex

      I had built the NRF tester and had perfect coverage with no drops in my apartment before (with signing!) from any of my NRFs.

      To test further I even put one of those plateboards for testing NRF to my gateway. Added external power from another source.
      Did the same to my NRF tester but still it fails.
      Have put them close and also gone around in my apartment to eliminate distance signal error, still the same.
      So only difference is mysensors 2.1.
      However, since no one else is complaining then maybe the problem IS with my setup.
      Or could also be that no one else has updated ๐Ÿ˜‰

      I'm using Arduino 1.6.11, maybe I should install 1.8.1?

    • RE: ๐Ÿ’ฌ Battery Powered Sensors

      @hek , I've read that post several times ๐Ÿ™‚
      Since it was so outdated (2 years) I naturally assumed the 'battery powering article' was a newer way to do it (especially since mys2.0).
      Also, the post you linked to is attributed if you use no voltage regulator.
      And in the article this is also one of the things you are recommended to remove, hence making it even more confusing as to why the article describes another way than the post.

      @TimO , is this binding supported via mysensors MQTT gateway?
      In previous bending inormation you had some text indicating that you would implement it. But all that is gone.
      So I'm thinking you either implemented it, or aborted that feature ๐Ÿ™‚

      I was checking back on this bindning and it really has matured!
      On GitHub I see that there are some updates referring to MqTT protocol.
      Are they available in the JAR that is posted here?

    • RE: delay different functions in loop

      After some hours of sleep and refactoring everything, now I think I've managed to get everything working.
      I have some problem wrapping my head around "forceTransmit" command and how it works.
      Also, millis() is also something I have to learn ๐Ÿ™‚

      Here is the code if anyone finds it interesting.
      What it does is measure soil moisture every hour and sends info (normal forkthingie).
      Also reading every 30 seconds for temperature and humidity (si7021)
      If humidity changes by 1 or temperature by 0.2 it will send info.
      If no info has been sent it will force send info every 20 minutes.

      3 Relays are there to power water pumps and a LED strip.

      i have now semi-learned the use of functions, which is fun ๐Ÿ™‚
      cheers!

    • delay different functions in loop

      Well, it's been a couple of hours now I've been trying to get things to work but now I have to ask for help.
      I understand that you can call a function from the loop.
      I have combined the sketches: RELAY, SOIL MOISTURE and SI7021 (which is a temperature/humidity sensor).

      all parts are working as expected but I want for instance the soil moisture to only be activated and do it's stuff every hour or so.
      While the temperature/humidity should be checked every 5 minutes and send info if changed + forced every 30 minutes..
      I have gotten it to work, but it's not a nice sketch, and I have problem with the timings.
      Because if I call the functions they only work if I add a serial print to see if it's actually counting.
      If I comment it out, it will show everything like every 3 seconds..
      I understand my sketch is aweful, but it's the best I can do at the moment (still learning).

      Someone that could take a look and/or point em in the right direction?
      Thanks.

    • RE: Wall mounted 'mood light' v2

      Hey @AWI

      I have some trouble using this with MqTT messages.
      I can get alarm to go off by sending a payload of '1' to 'InMQTT/62/4/1/0/2' and subsequently turn it off with any other value.

      But I can't get the rest of your functions to work!
      If I read your code correct, to set a solid color I would have to send several MqTT messages to the children?
      Ex, I would have to send 'InMQTT/62/1/1/0/40' and payload ex 'Candle' first.
      Then 'InMQTT/62/1/1/0/2' with payload of '1' to turn it on?
      I was looking at the serial protocol and do not find what V_Dimmer is for type. (https://www.mysensors.org/download/serial_api_20#variable-types)

      Anyways, i cant get it to work properly, maybe you could shed some light (pun not intended ๐Ÿ‘ ) )?

    • RE: [SOLVED] After upgrade to mysensors 2.1 problems with radio module might manifest itself more.

      @Anticimex and @tekka .
      I just upgraded my GW (MEGA) and most sensors.
      I do not know what you did, but my range is incredible now (and everything works!)
      I had good coverage in my apartment before, but if I went outside my front door it started failing (steel security door).
      Now, I can not only go outside the door, I can actually go 3 stairs down in my building with AWIs NRF tester.
      Same hardware is used and nothing has changed from my part.

      Kudos and thank you.

      @Anticimex , eh, no apologies needed. I'm thankful mysensors is opensource and actually FREE!
      Cool that you found a bug and if I helped, I'm glad ๐Ÿ™‚
