@m26872 I will give a try and let you know... Thanks.

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.

Reading...
T: 20.29
H: 54
device ID: 50

@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 !?!?!

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

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.
