What it is

Write custom firmware for ESP8266 and ESP32 devices.

Real use case example

"A founder wants to create a smart home system. She starts by flashing Tasmota firmware onto her ESP32 devices, configures them to integrate with her home automation hub through MQTT protocol, and then sets up custom automations to turn lights on/off based on motion sensors, which she controls remotely using her smartphone. With Tasmota, she saves time and money by avoiding custom development from scratch."

When to use it
  • โ€ขWhen you need to automate IoT devices without relying on cloud services
  • โ€ขWhen you want to control ESP32 or ESP8266 devices using a web-based interface
  • โ€ขWhen you require local control over devices using MQTT, HTTP, Serial, or KNX protocols
Ready-to-paste prompt
ON Power1#State DO Publish2 tele/sonoff/POWER1 IF Power1#State = 1
Heads up: After flashing the Tasmota firmware, the device will reset to its default IP address of 192.168.4.1, so you will need to access it at this address to configure the Wi-Fi settings and avoid having to re-flash the device
