Functions implemented in the home automation system

Here is the functions that can be adressed with the architecture described here, all these functions are integrated and can be linked together if necessary

Alarm system

  • Presence detection by PIR and door/window sensors
  • Automatic detection of house mode (presence/out) by wifi and geolocalisation
  • When a presence is detected start a siren and send an email
  • Smoke detector make the home automation siren start and send an email
  • Camera motion control (extra added later on)
  • Presence simulation

Energy monitoring

  • Instant consumption monitoring
  • Dayly consumption monitoring
  • Voltage measurement
  • History charts


Media

  • Squeezebox integration
  • Play/stop change internet radio
  • Adjust volume

Home automation

  • Switch ON/OFF plugs remotely with an android application or a web site
  • Monitor temperature and humidity of rooms
  • Weather forecast (integrated from yahoo data)
  • Text to speech, when someone wake up give the weather forecast for example
  • History charts of temperature and humidities
  • IFTTT integration to build scenarios with extra services
  • Google calendar integration (switch on/off items following a calendar)
  • Wifi on/off control


Maintenance

  • Siren volume adjustement (for maintenance purposes)
  • Monitor if arduino is alive
  • Measure voltage of arduino power supply
  • Home automation box temperature monitoring
  • Measure CPU/memory/temperature of the raspberry pi and openhab

433toMQTTto433 - Bidirectional ESP8266 NodeMCU gateway between RF 433Mhz signal and MQTT

The goal  is to act as a gateway between 433Mhz sensors and a MQTT broker or between the MQTT broker and 433Mhz actuators, It enables to:
receive MQTT data from a topic and send RF 433Mhz signal corresponding to the received MQTT data publish MQTT data to a different topic related to received 433Mhz signal 
It can be an interesting part in an home automation system so as to interface sensors and actuators (wall sockets) with software like openhab.

List of compatible sensors here

The interest of putting this gateway to an ESP8266 and not on a raspberry pi is to be able to manage security actions at gateway level (power on a siren, cut power to certain devices) following RF data received by sensors without being dependent to the PI for security related actions.

Infrared IR, 433mhz and MQTT on ESP8266 bidirectional gateway OpenMQTTGateway

Following discussions on the home assistant forum people gave me the idea to add Infrared communication to the 433mhz gateway. 

The goal is to act as a gateway between 433Mhz sensors, infrared remote controls and a MQTT broker or between the MQTT broker and 433Mhz actuators, infrared devices, It enables to:
receive MQTT data from a topic and send RF 433Mhz signal corresponding to the received MQTT data publish MQTT data to a different topic related to received 433Mhz signal receive MQTT data from a topic and send infrared signal corresponding to the received MQTT data publish MQTT data to a different topic related to received infrared signal 
It can be an interesting part in an home automation system so as to interface sensors and actuators (wall sockets), your tv, home cinema, hifi ... with software like openhab or home assistant.

Adding infrared emitter to SONOFF RF BRIDGE

With the add of  SONOFF RF Bridge  to the OpenMQTTGateway compatibility list we were able to send and receive 433mhz by MQTT. 
The interesting thing with OpenMQTTGateway is the ability to have on one board several gateways (RF, IR, BLE and more to come ;-). 

The last versions of SONOFF RF BRIDGE as two IO free pins, why not using these pins to add a new gateway to this little cheap device and control more devices.



If we follow the interest of the different gateways you are more interested on RF and after comes IR infrared.

My choice came in this case to add an infrared emitter to the RF Bridge, with this gateway we are adding the capacity of controlling TV, DVD, hifi...

On the hardware side, I followed the same schematic for IR setup with ESP8266 with just a little add a protection resistor of 1K for the IR led.
The other resistor is connected between the transistor base and IO5 of the RF Bridge instead of D0.
The IR led is powered by the 3,3V of the Sonoff RF Bridge.

The schema:


Here is how i…
