IoThome: Smart Home Automation with Tasmota

IoThome is a standalone Tasmota ecosystem that integrates IoTextra I/O boards, IoTbase carrier boards, and IoTsmart wireless nodes into a ready-to-run smart home automation system — without writing firmware from scratch.

It runs entirely on-device. No external server, hub, or cloud dependency is required. Every node operates autonomously and locally.

The Problem: From Prototype to Product

Modern prototyping tools make it easy to build a demo but extremely hard to turn that prototype into a stable, maintainable product. Teams often redesign hardware from the ground up after using Raspberry Pi, Arduino, or similar boards — a costly and time-consuming process that burdens long-term support.

The Solution: Standardized Smart Home Nodes

The Make Things Happy platform eliminates the prototype-to-production gap by standardizing I/O hardware through the IoTextra module family and providing two clear integration paths: IoTbase for full-featured solutions using SoMs, and IoTsmart for compact wireless nodes. All modules are Open Hardware, well-documented, and usable independently.

IoThome unifies these hardware options for smart home users through a consistent software layer on top of Tasmota.

What Is IoThome?

IoThome is a software layer that sits on top of Tasmota and the IoTextra hardware family. It provides ready-to-use Berry drivers, Tasmota templates, and automation scripts so you can go from hardware assembly to a running smart home node without writing firmware from scratch.

IoThome is not a cloud service and is not locked to a specific microcontroller. The same workflow applies whether you use ESP32-S3–based IoTsmart modules or any ESP32-based IoTbase configuration.

Home Automation Workflow

A typical IoThome node follows five steps from hardware to running automation:

See the complete setup walkthrough in the Setup Guide (~20–30 minutes from unboxing to a running node).

Tasmota at the Core

Tasmota is the communication and management backbone of IoThome. It handles Wi-Fi connectivity, OTA firmware updates, MQTT publishing, and the local web interface — all out of the box.

IoThome provides:

• Pre-built Tasmota factory binaries matched to each supported SoM
• GPIO templates that configure pin assignments automatically on import
• Berry drivers for I²C hardware — ADS1115 (analog input) and TCA9534 (digital I/O expander)
• Ready-to-use autoexec.be application scripts for common automation scenarios (e.g. Smart Farm)

Tasmota’s MQTT output is compatible with Home Assistant, Node-RED, Blynk, and any standard MQTT broker including Mosquitto, EMQX, and Aedes.

Demo: Smart Farm Application

IoThome ships with a Smart Farm reference application — a real-world Berry automation script for irrigation control. It reads soil moisture and analog sensor channels on a configured interval, drives relay outputs when thresholds are crossed, and logs every event. The control loop runs entirely on-device: if the MQTT broker goes offline, irrigation keeps running.

A complete node pairs an IoTbase NANO or IoTsmart ESP32-S3 module with the IoTextra Combo mezzanine — analog inputs for sensors, digital outputs for relay coils, wired to solenoid valves. Setup takes under 30 minutes.
