    This is an example of server using NodeMCU(ESP8266) using library: rDHT v2.00, rESP8266 v1.00, rESP8266Wifi v1.30, rOneWire v1.00, rRandomAccessFile v1.80.
    For NodeMCU(ESP8266), you need to change DHT library line 122 in dht.cpp
    For Arduino, DHT library, remain original
    Schematic is this:
    Server read sensor and send data using B4RSerializator only when a client is connected. This monitor my home heating system, radiators, indoor temperature and humidity , outdoor temperature and door open/close.
    Partial server code here:
    And client build with B4A.

    Hi...I have a Home Automation application where I need to use it as a WiFi-to-Serial link to an X10 PLC interface. I would like the option of it simultaneously acting as a hub for other HA related sensors using multiple WeMos D1 minis.
