Some time ago i hacked a sonoff switch to be able to put my own software on it. This was a simple internetswitch. In the mean time i greatly improved the software for more flexiblity and lower energy consumtion. One of the great improvements is the possibility to update the software "over the air". No need to flash the ESP, just provide a link to the new software and it wil update.
An overview of the current features:
- Switchable via the webinterface or the pushbutton
- Timers can be configured directly from the webpage.
- We can configure 4 timers with day of week distinction.
- Also a count down timer can be configured.
- Switching time can be configured relative to sunset/rise.
- It knows sunset/rise based on latitude/longtitude/timezone.
- It also knows summer and wintertime in Europe.
- Use it as a thermostate ot hygrostate with a DHT22 or DS18B20.
- Configureable as a motion sensor.
- Software can be updated over the air (OTA).
- The sonoff can be secured with a password.
- It has a "forgotten switch security". (on-time max. 6 hrs)
- It can send data from a dht11 sensor to Domoticz
This all makes it a real smart device......
