An Application running on Android Phone will get the temperature and humidity values from the Nodemcu and it will also control the 4 Relays, which are connected to the Nodemcu, all over WiFi channel, so using this setup, you can control your appliances using Android Phone over WiFi.

Nodemcu Code is written in Arduino IDE and Android Code is written in B4A.
Source Files can be downloaded from the Download file attached below.

In the above post, you can control relays and get temperature and humidity data only on Local Network.
But now, using CloudMQTT Server, one can get temperature and humidity data, plus control led(can be extended further), using Android phone, from any corner of the world.

Download Link is attached below.

The following folders are present.
Application -> Consist of Nodemcu/ESP8266 Source Code written in Arduino IDE, to measure temperature and humidity data from DHT11 sensor and publish it to the CloudMQTT Server.
Monitor -> Android Application written in B4A, to publish led state to NodeMCU using a Toggle Button, and it also subscribe the temperature and humidity data from the CloudMQTT Server.
Py-App -> Windows Application written in Python and GUI developed using PyQt5, to publish led state to NodeMCU Using Push Button and it also subscribe the temperature and humidity data from CloudMQTT Server.
