Hey

Im not really getting it is this a gateway for mysensors nodes or for mtqq Nodes with esp stuff? I dont really getting it. Do you need a esp8266 wifi gateway to get a wireless gateway for mysensors stuff or is like. Mysensors gateway ---> Esp8266 gateway --- Esp8266 node.

Sorry i dont really understand but im intressted in buying 8-10 sonoff for my window lamps, and i want them to work with domoticz

No it doesn't only sometimes

Its one in the garage it is never below 0- C this one was alive the longest the other one was dead in 2-3days and maybe as coldest it was 10- C. I'm starting to think it's something wrong with the gateway

Hello i wonder how you do then you put sensors outside mine stop work after a few hours i guess its becouse its cold here and maybe humitiy? then i take them inside for while it start working again. i think i need a waterprofe case or something

Ok i redid everything from skratch and now i got it working atleast with 1 node havnt tried the other yet.
I used the code miljume did link the only line i changed was
#include <SI7021-master\SI7021.h>
to
#include <SI7021.h>
It is working but it shows up as 2 nodes in domoticz
1401 0 TempHum Temp + Humidity WTGR800 20.9 C, 35 % 2017-01-19 17:59:05
1400 0 TempHum Temp + Humidity WTGR800 20.7 C, 34 % 2017-01-19 17:59:05
anyone know why?
also this does report every 60sec will this be short battery life?

I have problem to get my sensors to work. Thay start up and shows a not so accurate value sometimes and thay report once or twice but then never again. I thought it was because buad rate was wrong in the MyConfig.H file. Now i changed that and i tried a few different codes and librarys. Nothing seems to work.

So my question is which code and library should i use?

I got the slim node and sensor as in the first post.
Im running 1mhz optiboot bootloader from the slim node thread
And i updated mysensors to 2.1.

I'm going to try do this with the slim node and a cr2032 battery. Which cap do you recommend using to help battery?
