Flair 58 MQTT Gateway

This repository contains firmware to integrate Flair 58 Preheat system with a smart home automation system using MQTT and Raspberry Pi Pico W microcontroller.

Disclaimer: controlling heating devices remotely is dangerous; wiring into electrical devices is dangerous and voids their warranty.

Pins

See Pico W Pinout for the pin names.

• Pin 3 (or any other), Ground: Common ground, GND.
• Pin 16, GP12: Low LED, D2.
• Pin 17, GP13: Medium LED, D3.
• Pin 19, GP14: High LED, D4.
• Pin 20, GP15: Control button, S1.

Preheat controller board does not provide enough 5V current for Pico W, so Pico W has to be powered externally (for example, by USB).

Home Assistant Config

The following configuration.yaml snippet adds two entities to Home Assistant:

• A sensor entity, which shows the current state of the preheat controller.
• A select entity, which allows to set the desired state of the preheat controller.
