SmartEnough is a DIY smarthome project

Mono repository for all my smarthome needs.

In progress. Gathering and growing my smarthome tools.

IO Controller MainBoard

• Cheap!
• Easy for DIY, even on a breadboard or soldered with wires.
• Uses available ready modules so there’s not much to solder yourself.
• Assumes a distributed (using CAN), resiliant architecture.
• Based on STM32G431 WeAct module. Could be migrated to use other - eg. stm32f4.
• Has rudimentary (and optional) ESD protection using esda6v1s3.

Components:

• [https://github.com/WeActStudio/WeActStudio.STM32G431CoreBoard.git]
• CAN module, TJA1050 based.
• RS485 module, HW0519.
• Optional PCF8575 IO expanders (1-3)
• LM2596 stabilizer (30V+ -> 12V)
• MP1584 stabilizer (12V -> 5V)

Greenfinger

Automatic plant watering using ESP8266 (or ESP32) using Micropython. Integrates with HomeAssistant over MQTT:

• Reports status (humidity, operations).
• Can be controlled over MQTT (more water NOW).

It was 100% stable during a period of about a year. Plants died for unrelated reasons. ;)
