Add and manage Tasmota devices in Home Assistant with TasmoAdmin add-on

If you have multiple Sonoff or DIY Tasmota devices (such as smart switches, sensors, etc.), it can be difficult to manage them even if you assign static IP addresses to them. You still have to keep track of their IP addresses to access and manage them individually.


With the TasmoAdmin add-on (formerly SonWEB), you never have to assign a static IP address to a new or existing Tasmota device or keep a note about which device is available at which IP.


What is TasmoAdmin Add-on?

TasmoAdmin is a Home Assistant Community add-on created by Frank Nejoff You can install it on the Home Assistant server to manage all Sonoff-Tasmota devices via a central web interface. The add-on can automatically scan your wireless network, list all Tasmota devices with their IP addresses, and display various other important information about the devices.

With TasmoAdmin on the Home Assistant, you can:

  • Automatically scan and list Sonoff-Tasmota devices on your network
  • Manage multiple sensors and switches
  • Check the status of all devices, whether they are online / offline
  • Configure or make changes to devices from a single web user interface
  • Update one or more devices using OTA simultaneously
  • Download the latest firmware automatically

TasmoAdmin also comes with a responsive web user interface and a night mode.

You can either purchase Sonoff hardware or flash the Tasmota firmware on ESP8266-based boards, such as the D1 Mini or NodeMCU, to build your own smart devices and sensors from a private smart home, such as:
