what is tasmota

Tasmota is a fork of Tasmoco, open-source firmware for WiFi-enabled ESP32 microcontrollers.

Sonoff has created Tasmota to provide home automation users with their Tasmota compatible code without the need to buy expensive hardware and put it together themselves.

Sonoff uses Tasmota to offer its customers products that are both affordable and easy to use. Tasmota enables you to control your Sonoff Devices automatically and manually. 

Read on to discover what Tasmota controllers can do and how to install Tasmota in your home.

I will discuss some of the intricate details of Tasmota use, including zoning. We will look at some of the advantages and disadvantages of using Tasmota for your home automation needs. Let’s get to it!

What is Tasmota?

Tasmota is a platform for Tasmota firmware that allows you to control Sonoff devices from the Tasmota web interface.

Tasmota is a DIY Home Automation system, which can be used with other hardware as well. Tasmota can be used with Tasmota firmware, the Tasmota web interface, and Home Assistant.

The Tasmota platform is open source and free for use under the MIT license.

Tasmota provides a broader range of possibilities than Sonoff alone to get your devices connected and control them from anywhere in the world (your phone).

You can program an internet-enabled voice assistant like Alexa to do it on your behalf.

Tasmota is an open-source firmware for WiFi-enabled ESP32 microcontrollers.

Tasmota enables you to take full control over your Sonoff devices, either automatically or manually.

With Tasmota installed on a compatible device, the user can update their product using OTA (over-the-air) updates from our servers or from the device itself.   

How To Install Tasmota

Tasmota is free and open source, meaning that Tasmota can be installed on any Sonoff device.

Manual installation is simple with the provided instructions. Tasmota has two ways of installation:

  • Automatic Installation (recommended) – Tasmota firmware will automatically install onto a compatible device if the Wi-Fi connection is established with its servers.
  • Manual Installation – If you cannot establish a Wi-Fi connection with its server, you can follow some simple steps provided with your device to upload Tasmota firmware onto your Sonoff device manually.

If Automatic Installation Fails, To Manually Install You Will Need:

  • Wi-Fi enabled device (your router) with USB port and Internet connection.
  • A self-powered hub if the router does not have a built-in one.
  • Tasmota compatible device.
  • Tasmota firmware update package for your router and Tasmota compatible device (download the appropriate file from the Tasmota website) 

To Setup Home Automation System with Tasmota Firmware:

  • Configure Your Wi-Fi Router For Tasmota Project. If you have not done this before, check out our tutorial on configuring a Wi-Fi router for a home automation project. In addition, make sure that both the router and hub connected via USB are turned off at this point! 
  • Find The Device MAC Address on the Tasmota Website. Tasmota will show you the MAC address of your Tasmota compatible device in their database, and this is what we need to get it working with Tasmota firmware!
  • Configure Your Tasmota-Compatible Device for Home Automation With Tasmota Firmware.

Sonoff devices are mainly used for Home Automation purposes, but they can also be configured as a wireless remote control for different Tasmota-compatible devices.

The Tasmota web interface is the core of the Tasmota system, and it provides all functions to control your devices.

Your browser must be connected to the Tasmota web interface for you to use other features like Tasmota mobile app on a smartphone or TTS integration with Alexa assistant, etc.

What Is Home Automation?

Home automation is the ability to control a house with Tasmota devices automatically.

You can set your home up so that Tasmota devices will respond when certain events happen, such as motion detection or if someone turns on/off lights in one room of the house.

Home automation uses electronic devices, communication technologies, and home networks to monitor and control the activities inside a house.

Tasmota is one sure way to get your house automated for less than $100 if you are interested in DIY projects.

The Tasmota server runs on Linux-based machines.

It connects to a Tasmota Server running inside each Sonoff device through publish/subscribe messaging protocol. The Tasmota software package contains all you need: 

  • Firmware for any supported hardware platform
  • Web interface frontend
  • Command-line tools allow user configuration via API calls from anywhere on any internet-connected device (PC, phone). 

Home automation with Tasmota has three phases:

  • Monitoring Phase – Tasks such as observing data, collecting sensor information, and monitoring environmental indicators.
  • Control Phase – Tasks such as controlling the environment to reach the desired state or performing an action that other systems do not perform automatically.  This task may involve just one device, multiple devices in the same system, or many sensors working together to control different aspects of a home’s climate.
  • Logging Phase – Tasks such as monitoring environmental indicators or recording sensor information over time to detect changes that may indicate a problem with one’s home or property. This task often includes logging data related to different sensors on your Tasmota platform, which can occur automatically based on set parameters or manually when you look back at how things were done before an event occurred. 

You might also want certain devices activated during specific times only, such as turning off the lights when the sun goes down or turning on a fan to maintain an optimal temperature.

Video recording and home security are other important capabilities of this system. Tasmota is excellent for these types of things!

How Does Tasmota Work?

Tasmota works with Sonoff devices.

Tasmota firmware will work with Sonoff devices, but Tasmota is not limited to this.

Tasmota can be used together with other hardware as well.

To see a list of compatible devices, head to Tasmota’s website or go with a Sonoff device.

Tasmota software runs on a host computer, connects to the Tasmot server, and then automatically controls all the connected Tasmota enabled devices in your home from any internet-connected device (phone or PC).

The installation process for TASMOTA only takes about five minutes, and there’s no programming required!

Once updated, Tasmota enables users complete control over their devices from either the cloud or locally via a serial port terminal.

As Tasmota is a fully featured firmware, the Tasmota interface supports all features of Sonoff devices.

What Are Some of Tasmota’s Features?

The Tasmota Firmware allows you to control and manage your home automation devices with Wi-Fi or a serial port.

Tasmota can be accessed via any Internet-enabled device to configure your Sonoff/Sonoff RF settings without being near it.

In addition to configuring Tasmotas’ Wi-Fi settings from a remote location, users can access their serial ports for configuration directly through an ESP32 development board wirelessly connected using a USB cable.

This feature also provides Tasmota to Tasmota communication.

Tasmota firmware is designed with the user in mind. It provides remote access to your Sonoff/Sonoff RF devices via a web browser or an Internet-enabled device and allows for configuration settings without being near it.

Tasmota Zones and How They Work

Tasmota’s zones are designated spaces where you can control what happens.

These configurable boundaries help to provide a more detailed and individualized experience for your home automation needs.

Zones are Tasmota’s way of grouping devices.

Zones allow you to control multiple Tasmota device groups with one single TASMOTA Web UI login on your smartphone or other supported device.

You can create additional zones as needed and rename them accordingly.

Tasmota Zones vs. Security System Sensors: Tasmota’s zones don’t replace security system sensors but rather complement their functionality in an emergency by adding another layer of protection.

The Benefits of The Sonoff Home Automation Platform?

Tasmota on the Sonoff Home Automation Platform comes with various benefits and features that enhance the conveniences of your home. Some of the services of Tasmota include:

  • Automating tasks like lights or appliances with ease; managing different electrical circuits (rooms) separately from one device using Tasmoton’s zoning features.
  • Tasmota can be installed and configured using a browser, so no programming skills are required.
  • Tasmota also runs on the Linux operating system, which is open source and free to use.
  • Tasmota is a fresh start. It can be installed and configured using a browser, so no programming skills are required.
  • Installation is easy for anyone with little background in DIY projects or electronics.

Tasmota has been designed with home automation in mind, starting from scratch without any old code inherited from previous Sonoff Home Automation Platforms like Wi-Fi or Z Wave.
