NodeMCU Kube home automation multisensor Build - Part II (Arduino)

NodeMCU Kube Multisensor Build - Part II - focusing on the Arduino software load of the NodeMCU home automation Multisensor for openhab, including configuring sensor settings like OLED display type, deepsleep functionality, motion sensor, OTA update, MQTT topics and Wifi settings. We'll also take a quick look at the temperature sensor calibration, to be discussed in Part III.

I use the sensors in my openHAB home automation setup, for reporting temperature, humidity, motion, etc..These openhab sensors are very cheap, easy to make and look professional, the openhab sensor OLED screen also allows easy local monitoring as well as remote temperature sensor reporting, and the external sensor connector allows adding other types of sensors to this DIY home automation sensor.

Hi, the sketch returns this errors: In function 'void loop()':

ESP8266-PIR-OLED-Arduino:197: error: no matching function for call to 'DHT::computeHeatIndex(float&, float&, bool)'

float hic = dht.computeHeatIndex(t, h, false);

^

note: candidate is:

In file included from

note: float DHT::computeHeatIndex(float, float)

float computeHeatIndex(float tempFahrenheit, float percentHumidity);

^

note: candidate expects 2 arguments, 3 provided

exit status 1
no matching function for call to 'DHT::computeHeatIndex(float&, float&, bool)'

Am i doing something wrong ?

Hello, can you calibrate or set an offset for DHT11 or AM2302/DHT22 in Tasmota? I'm trying to setup a sonoff basic r2 as a light switch with a sensor DHT11 on a spare GPIO to control light and measure the temp/humidity in the room.
Great work on your channel.
An off topic question, why you choose OpenHAB and not Home Assistant?

Hi Bk,
I installed the temperature sensor in one of my room. But one problem i am facing is it does't show the change in temperature directly . It shows only after i reset my NodeMCU. What could be the reason for this bk and how to solve this problem? Are you facing the same issue at your side?

Very good work. I have connected the module with WifiManager, why not see nothig to serial monitor?

[hckywrestler]

after i have set up the sensor with the new wifi setup how would i change the wifi credentials even after reflashing the node mcu it still only connects to the first AP...
Also all of my temperature and humidity readings are jumping down to -1 every other refresh i tried different node mcu and different dht22s

When I check the sketch I'm getting the following error: 'class WiFiClass' has no member named 'mode' any idea?

[grahamjones]

How do you get the WiFiManager.h says it can not find it

Thank you for your videos. i have been trying to upload your sketch to my nodemcu 1.0. i have managed it one one nodemcu but i cant get it to load on another and have tried changing so many things i cant remember what i have started with. I have down loaded the lasted sketch from github and when i try to upload it at upload speed of 9600 as it says to on my board it flashes all the way to the end then shows "An error occurred while uploading the sketch" if i try uploading at any other speeds it uploads but i dont think it works as there is no display on the screen and nothing on mqtt, would you have any idea what the problem maybe?
