Design
- Use insteon 2450 to switch fireplace low-voltage control
- Control Insteon 2450 via Thermostat - Heat Control (insteon address: 14 23 AC 3) via ISY program
- Rewire house heater to use the 2nd stage heater control on the thermostat
- Sense fire place heater via 2450 input
- Engage house heater fan via ISY program
Design Rev 2.0
- create fireplace controller with raspberry pi zero + OLED display that fits into single gang box with decora faceplate
- Inspired from here:
OLED color display based on SD1331
- the Oled display which will fit into decora blank at this link
- programming the display https://media.readthedocs.org/pdf/luma-oled/latest/luma-oled.pdf
- Rudimentary bit-banging Python driver: Gist at Github
- Native driver package at Github
- Hooking up the display via SPI https://learn.adafruit.com/ssd1306-oled-displays-with-raspberry-pi-and-beaglebone-black/wiring
- Connect display ground to Raspberry Pi ground (black wire).
- Connect display VIN to Raspberry Pi 3.3 volt (red wire).
- Connect display CS to Raspberry Pi CE0 (yellow wire).
- Connect display RST to Raspberry Pi GPIO 24 (blue wire). You can alternatively use any free digital GPIO pin for the reset pin.
- Connect display DC to Raspberry Pi GPIO 23 (cyan wire). You can alternatively use any free digital GPIO pin for the DC pin.
- Connect display CLK to Raspberry Pi SCLK (orange wire).
- Connect display Data to Raspberry Pi MOSI (purple wire).
OLED B/W display based on SSD1306
- address 0x7B
