Remote control over a house? Can a PI be the HUB? Is there a working system out there?

Sat Dec 08, 2018 7:04 pm

Hi,

I do want to build a system that is fully controlled from a smart phone/tablet/computer.

The system is going to monitor different sensors and give an alert when different actions happens.


Cabin 1
Raspberry PI (wifi og gsm/lte)
|--Door sensors (wireless)
|--IR sensor (wireless)
|--Other sensors (wireless)

Cabin 2
Raspberry PI (wifi og gsm/lte)
|--Door sensors (wireless)
|--IR sensor (wireless)
|--Other sensors (wireless)

Cabin 3
Raspberry PI (wifi og gsm/lte)
|--Door sensors (wireless)
|--IR sensor (wireless)
|--Other sensors (wireless)

The PI is connected to main power, the sensor should have a long lasting battery that is rechargeable.
The sensor will notify the system when power is low, and it should be charged (the time when alert is coming should be adjustable)

The system should be easy to use, but have an option so you could tell that you don't want an alert if not BOTH door sensor AND IR sensor (or some else sensor) is trigged.

I see there is alot of systems/OS out there that you can run on the PI. Anyone know if there is any I could use for setup?

long lasting battery temp/humidity sensors and a pi ble crack..

a similar device used for plant pots

for incorporating most basic cheap 433mhz door sensors pirs push button controllers etc you can use a £8 sonoff RF bridge reflashed with tasmota firmware a firmware for home automation you can flash onto any esp8266/5 device https://github.com/arendst/Sonoff-Tasmota/wiki

EDIT: the Rf Bridge is a simple device once flashed with tasmota and configured to your net, it will simply repeat any 433mhz code it can 'hear' and decode as a mqtt message/payload, it wont hear everything.. especially more sophisticated codes.. your pi can sit subscribing to these topics and respond accordingly

Any custom sensors you want to add to your system can be connected to an esp8266 dev board such as a wemos d1 and can then be configured via the tasmoata gui ..

On your pi host the mqtt broker mosquitto, and some s/w to present a front end gui and a mechanism for complex rules you cant embed on devices.
I use node red but openhab and domoticz are popular systems.

Well thats the way i went ;)
