Hey everyone !

I created an open source Home Automation system called L.I.S.A. it’s a node js project based on (Trails/Express) for backend and Angular 4 for frontend. The system run great on raspberry pi 2/3 and allow you control your devices by voice commands. The architecture works with plugin that give the compatibility with new devices (widgets and voice commands).

I’m working on giving voice to L.I.S.A. with by default PICO TTS and additional support for Amazon Polly if you have/create an account for it.

I already start the compatibility with the Matrix Creator Board by giving feedbacks with leds and use microphone array for offline detection (with snowboy) of the keyword and then use Google speech. Next things will be IR commands and get values of sensors.

About plugin I already have Kodi plugin that works with voice commands (manage play/pause/stop, launch a movie or an episode of tv show), also have plugins for Sony VPL projector, Philips HUE Lights, IP Webcams…

There a lot to do in this project and I need help to create more plugins to be compatible with more devices (like zwave, mqtt, ifttt…) but also to work on front part (user profile, improve ui…). I also need help on core of L.I.S.A. to stabilise the architecture, I also think about put it under docker for easier deployment but don’t know anything about it.

As my system is all about DIY I would like to be compatible with MySensors protocole but never had the time to test it if someone have good knowledge and want to be part of the adventure don't hesitate to join !

Here are the repos https://github.com/mylisabox any feedback is appreciated

@AWI thanks for pointing me to the doc it look great ! I will give it a try

Hi,

It will be great to have an open source version of rfxcom, I mean a library that can manage multiple radio protocoles. RFXCOM is quite expensive and I think mySensors library can also support other radio protocoles to be compatible with other devices on the market.

I see on an other thread maybe mySensors will be compatible with radioHead library who is also compatible with 433Hz radio transmitters. So we can work to a new api who can manage all 433Hz protocoles like RFXCOM do. Like this we can have a RFXCOM like for small $$

Anyone will be interested about a such project ?

For example we can create a top layer on mySensors and make serial communication become :

protocole;protocole-params...;

Few examples for :
MySensors :

mysensors;node-id;child-sensor-id;message-type;ack;sub-type;payload\n

Chacon/HomeEasy :

homeeasy;sender-id;group;state;receiver-id;dim-level

same for all protocol we want to support

@hek sorry I will try to explain a little more
I'm trying to create my own home automation box (hardware and software) and want to make my own connected devices too. All of this speak with radio wave.
I need something like :
Box -> Command1 -> Device1
Device1 -> State1 -> Box
Box -> Command2 with params -> Device1
Device1 -> State2 -> Box
Box -> Command3 -> Device2
....

I read mysensors have an auto mode for giving unique ids for devices and that's also what I want. This id is in 7 header bytes ? The sender id is also in it ? Cause I don't want my device to answer to another box... for security.

I maybe try to sell my box and devices so I need a protocole who is supported by other box (jeedom...). I want to be sure that mysensors is the right choice for doing this

Thanks a lot for helping !

@Dirk_H thanks ! Before I start with mysensor can you confirm I can send and receiver anything by radio ? I really need to send multiple command to my device and my device need to send it's state.

Also need to know if I want to use my device with jeedom or domoticz what I have to do ? It's already compatible because I use mysensors ?

Thanks a lot for your help

Thanks @hek
I read for the nRF24L01 : This product is not recommended for new designs. Nordic recommends its drop-in compatible nRF24L01+ or for a System-on-Chip solution the Nordic nRF24LE1 or nRF24LU1+.

nRF24L01+ will work great with MySensor library ?

Hi,

I'm trying to create my own connected device for my home and want to use radio to speak with it.
I have 433 radio emitter/receptor but I don't know witch radio protocole use.

I need to send commands to my device and the device need to send his state to the controller.

Anyone can tell me witch radio protocole I can use to do this ? Chacon doesn't get the state back, z-wave and enocean are proprietary... I'm lost with all protocoles

Thanks
