My automation project keeps evolving.

Here is an image of what one of the sensor/display nodes looks like now.

The image is of the IOT Node Base. Contains power regulator. ESP8266 based on the Wemos D1 Mini.

A basic sensor node consists of the board above and sensor. An advanced node would consists of the base node board, and a expansion board that would plug into the back. The expansion board could either be a more advanced sensor integration, or a actor board.

An actor board, would allow for a node to control various funcations, relays, pwm, etc. and also accept input from buttons, etc.

Display nodes are similar to above but connect (currently) to a 4×20 LCD display. They also have the ability to accept actor expansion boards.
