ESPWatch With Weather Forecasting

The ESPWatch is based on ESP12 WIFI module, it gets the date/ time and the weather forecasting in few days from Internet server, and can also remote control the local instruments, such as Relay/LED/Fan. With this learning, you will learn the basic skill of components soldering/Arduino Programming/WIFI usage/Basic http protocol, the first& easy step to get into the electronic/programming world.

There we also prepared simple case/watchband, so that you can get it works on your wrist within few minutes.

The ESPWatch is a kit for customer assembling, users should firstly solder all the components. A soldering iron and some Tin wires are needed.There the detailed soldering guide at youtube.

The ESPWatch is based on the Arduino IDE, if there no Arduino IDE in your Computer, please download the latest Arduino IDE at:

https://www.arduino.cc/en/Main/Software

Install the IDE and all the related drivers and Start the IDE, there would be a simple sketch by default.

Start Arduino and open Preferences window, and enter https://arduino.esp8266.com/stable/package_esp826... into Additional Board Manager URLs , and clink OK.

And then you should find the ESP8266 in the Arduino IDE: Tools->board-> boards manager, let’s install it by click the “install”:

After the installing, you can find the NodeMCU 1.0(ESP12E module) platform at Tools-> Board Menu:

There at least these libraries need to be installed:

• Ntpclient library
• Arduino-mqtt: https://github.com/256dpi/arduino-mqtt
• Thingpulse ESP8266 OLED SSD1306: https://github.com/256dpi/arduino-mqtt
• TimeLib: https://github.com/256dpi/arduino-mqtt
• ESP8266 Weather Station
• JSON Streaming Parser by Daniel Eichhorn

We can seach "ntpclient","lwmqtt", " ESP8266 OLED Driver for SSD1306 display","timekeeping",“ESP8266 Weather Station”, ”JSON Streaming Parser” to find these libraries in library manager, and install them.

Open the sketch->include library->manage libraries

1. Log-in the cloudMQTT(if no, you need to register an Account)

2. And Create a new instance

3. And then here you can get the instance info:

We use the thingpulse(https://docs.thingpulse.com/how-tos/openweathermap-key/) to get the weather forcasting data, the final data from openweathermap (https://openweathermap.org/price).

Let’s use the free data.

After regestering, you will get your API key , And you can also check your city ID at the website https

Connect the ESPwatch to PC with PL2303 UART wire, the drivers at: http://www.prolific.com.tw/US/ShowProduct.aspx?p_... After driver installed , it will act as a COMM port.

Connect the PL2303 wire to ESPwatch programming port:

Open the watch.ino sketches:

1. Change SSID and passowrd of the Wi-Fi, 2. Modify hostname, port, user and user_password for MQTT, 3. and the weather_map_ID and Location_ID;

2. We can now update the codes to ESPWatch now. Select the right COM prt and board in Arduino IDE.

3. Hold the FLASH button; Power on the ESP8266 by the SW1, while the FLASH button holding on, to put ESP8226 into bootloader mode ,and click the upload to start the programming:

The ESPwatch can be also use to control other modules, such as the ESP relay: https://www.makerfabs.com/index.php?route=product/product&product_id=534&search=ESP+relay, and thus to create remote control application, such as AC lamp/Fans.
1. Create a new MQTT instance,Log-in the cloudMQTT(if no, you need to register an Account), and create a new instance。

2. Sketch Modification. Open the sketches relay.ino, change SSID and passowrd of the Wi-Fi, and modify hostname, port, user and user_password for MQTT.

Noted: port must same as the watch.

3. Programming. Plug the ESP-01 on the ESP8266 debugger, and programming the ESP module, Select the right board to begin the programming

And now you can connect the Relay to your AC lamp/Fan,etc, to make it remote controlled by the ESPWatch.
