I was planning to use a NodeMCU v2 (ESP8266) (with usb charger) and add these sensors: https://www.modmypi.com/raspberry-pi/se … ure-sensor
They have a digital output. I wanted to connect 5 of these sensors to different GPIOs of one NodeMCU.
Then I wanted to integrate the NodeMCU with the sensors into OpenHAB2. I did read that I need to do that with MQTT.
Can anybody confirm if it is possbible to use several sensors on one NodeMCU with ESPEasy and integrate it with MQTT in OpenHab2? I just need digital output of the sensors.
Or is there even a better way?
