 # Low Power Thermostat [![Build Status](https://travis-ci.org/joaquimBS/LowPowerThermostat.svg?branch=master)](https://travis-ci.org/joaquimBS/LowPowerThermostat)
 
 Here are the code and schematics of a IoT enabled, low power Thermostat, based on a [Moteino](https://lowpowerlab.com/guide/moteino/) board. It has a build-in 868MHz radio to transmit information to a base station and, therefore, push data the cloud.
 
 The thermostat itself works just as a switch to the heater control line; no AC supply is needed.

 - Current temperature set point and ON/OFF modes are configurable through an Android app. :-)
 - Low power (idle current of ~25uA). No AC supply needed. Can run for months with 3xAAA, LiPo, etc.
 - OLED screen as a HID.

 - Connect the Thermostat directly to the Internet, keeping a low power profile.
 - Add an RTC in order to program the Thermostat based on week days, day time, etc.
 
+## Changelog
+
+### v1.0
+- First stable version.
+- Android app connection is working.
+- Issue. 250ms delay after temperature sampling to avoid incoherent readings.
