      So sad I still not getting it working with the slim node 😞 !!! Always same result either with internal 1mhz or 8mhz...

      Ok with the arduino micro 8Mhz all works good too.

    • RE: Slim Node Si7021 sensor example

      @m26872 Thank you. Yes I wanted to try with a pro mini 8Mhz but I need to prepare the pin 4 and 5. I will keep inform when I do it this week end.

      Thanks for the picture but with this nice setup it is difficult to make it bad :)...

      I includes wire.h like in the exemple in https://github.com/LowPowerLab/SI7021 but of course after I tried without. The nano was directly connected to usb and the slim through 3,3V USB to serial.

      @m26872 Sure I can do that. So I simplified the code to only focus on the si7021.

      Here it is: https://github.com/clempat/example-si7021

      And there the photo:

      Why actually my device id is 50 ? for what 50 stands !?!?!

    • RE: Slim Node Si7021 sensor example

      Hi everyone,

      First thanks for sharing. I love this slim node. But I am facing some issues I did not success to debug. So I use the code shared here for mysensors 2. I try with the mysensors exemple library (did not work at all). I try with the https://github.com/LowPowerLab/SI7021 which worked (at least for getting separately temperature and humidity and using the example file) on an arduino nano. But when I run this sensor with the slim node (red, boot loader 8mhz) and the code (for 2.0.0) I always get -46.85 for temperature and 118 for humidity. Otherwise the radio work normally.

      Winter is coming and I don't know what I could do anymore. Thanks to share you idea on this.

      With the example code I use on the nano. I get with the slim node:

      T: -46.85
      H: 118
      device ID: 50
      

      With Arduino nano:

      T: 24.34
      H: 43
      device ID: 50

    • RE: Lots of repeater nodes

      I was doing that once but in my case it was not the best solution.

      I have some nodes on battery and so they don't ask for ack.

      I would need confirmation but I think that if my repeater is not reliable (far from gateway or somewhere with bad reception) It could add some loss on the communications from final node to gateway.

      I try so to test different place using this: https://forum.mysensors.org/topic/3984/nrf24l01-connection-quality-meter to place strategically my repeater.
