-=== Tasmota === 
- 
-Tasmota is firmware providing support for various devices attached to an ESP8266. It has both and HTTP (web) and MQTT interface. 
- 
-It was primarily designed for SONOFF power switches but can be used with any device to give an MQTT enabled WIFI temperature monitor, for example. 
- 
-Here is an example seession for a SONOFF basic switch. 
- 
-Backup factory firmware.

-==Initial configuration== 
- 
-After target reboots connect to the tasmota Wifi AP to access the network configuration [[http://192.168.4.1/|page]]. 
- 
-Enter your SSID and password and the target will reboot. 
- 
-Once rebooted visit the target device again to perform device setup. 
- 
- 
-==Configuration== 
- 
-Change the device type, Eg. Generic and save settings. It will reboot. 
- 
-For an attached I2C sensor: 
- 
-Change GPIO4 to SDA, and GPIO5 to SCL.
