Home Heat Hub

1.6 Home Heat Hub – Nano V3.0 with ESP8266

A 2nd test was carried out connecting the transmit (Tx) and receive (Rx) lines of the ESP to the Nano
MCU GPIO 2 & 3. This involved sending AT commands to the ESP for initial setup and sending cipsend
commands for updating an online logging site (thingspeak.com) with temperature updates. Tests were
conducted by sending temperature readings every 5 seconds with very good and stable results (See
Table 1-2).

Further experimentations were carried out using a system designed by Igor Jarc of EasyIoT. The
EasyIoT setup provides a web server which can hosted be locally on a Windows or Linux system and
allows the ESP to be added as a node or multiple nodes for monitoring or controlling GPIOs. After
testing the server with the Home Heat Hub hardware it became apparent that this setup would
provide a solid platform to expand the system easily. By adding new nodes to the server, a full home
automation system could be realised.
