 ## What this program does
 - Connect to one of the known wifi networks
 - Read the soil moisture sensor
-- Automatically calibrates its sensor for min/max values
+- Automatically calibrate its sensor for min/max values
 - Fetch the settings associated with each device
-- Send the sensor value on the [eedomus](http://www.eedomus.com) home automation cloud. This part be easily replaced by an other home auomation solution.

 ## Known issues
 - Light reading doesn't work, it seems to be an hardware issue
 - Coming back from deep sleep is not properly handled, probably a software issue. It has no impact at this stage thought
 - The current consumption never goes below 40mA, thus making it unsuited for low consumption
-- The program might get stuck if there's a (even temporary) wifi connection issue. As such there's a timer-based software watchdog logic to restart the devicee when this happens.
