+ST_Anything v2.9.2
 ================
 
 **WARNING** - You must use the SmartThings Classic App with ST_Anything. 
 
 **WARNING** - If using an ESP8266, make sure you are using v2.3 of the Arduino ESP8266 Board manager (v2.4/2.4.1 introduced a memory leak causing ST_Anythign to crash after an hour or two.) 
 
 **Recent History:**
+- v2.9.2 - Added support for I2C devices - TSL2561(lux), MAX44009(lux), BH1750(lux), BME280(temp,humid,pressure), BMP280(temp, pressure), and improved TCS34725(color lux).  Added ST_Anything_I2C_ESP8266WiFi.ino example sketch to demonstrate I2C sensors.
+
 - v2.9.1 - Added Servo Motor support, tweaked all device handlers for simplification and supportability, numerous small enhancements and bug fixes over the past few months (view Github History for details)

 Note: Attempting to use all of these at once on an Arduino UNO R3 is likely to result in running out of SRAM on the UNO (the UNO only has 2 kilobytes of RAM.)  Using an Arduino MEGA 2560 with 8 kilobytes of SRAM is recommended if you want to run everything at once.  The ESP8266, ESP32, and MKR1000 platforms also have a lot more memory available.
