I think you've ran into a common problem with the esp8266. I noticed the same issue with some of my own ESP8266 devices. They tend to hang after a few days of operation. Just Google on ESP8266 hangs and you will find that you are not the only one. For Some situations solutions are provided on the ...

So it looks like it is supported whitin NodeMCU. Just connect it, load the library and replace the Json lines with the right ones for the barometric device and you should be fine.

So now it it time to put those mini sensors everywhere ;-) But first write a wiki on how to build and program these sensors so we can all put it everywhere :D Done! :D There now is a Wiki page "ESP8266 WiFi module" under "Protocols, sensors and integration". I've documented everything I've done and ...

I've fixed it! As it turns out I made a few mistakes in the script thats sends the data to domoticz. The working script is below. require('ds18b20') -- ESP-01 GPIO Mapping gpio0 =3 gpio2 =4 ds18b20.setup(gpio2) t=ds18b20.read() print("Temp:" .. ds18b20.read() .. " C\n") if(t==nil) then t=0 end tmr ...

I've been at this for a while now, but still without any success. I'm trying to get a temperature reading from a DS18B20 1wire sensor that is connected directly to an ESP8266 module wich has nodeMCU installed. The principle works. Ik can get it to connect to my wifi network, and with a simple ...
