Now concerning the Sonoff original software I got it working after around 15 minutes of messing around. For some reason the app also needed my location information, sound recording,  access to SD card and so on ….. so yeah not fishy at all.

After the update the device was basically just push switch. After the update no matter what I did I could not reconnect the switch to the app.

Luckily I bought it to hack it. So here we go ….

Wifi temperature logger aka “NodeMcu Arduino IDE MQTT DHT11 Node”. Part 3 (Node Red and dashboard)

In previous two tutorials we learned how to set up ESP8266 with arduino IDE as temperature sensing node. Now we gonna look Node Red side of things and will create dashboard for displaying the data.
