Ok fire1. if I have understood, you are going to use 1 only Arduino board to control all the equipments. You have made a codification based on the digital output of Arduino to select what element has to be activated.

That is a different conception to our home automation system. I only have a question. When you active one equipment, can it be able to be used in manual mode?

Hello fire1,

I am the development manager of the home automation system called functiodomo. We developed our own Arduino duemilanove version because we neeeded a fast connection to the AC electrical installation at homes. Now we sell them trhough our online shop to other developers.

You can find it at:
http://functiodomo.com/eshop/?tcp_product=placa-de-control-acduino-pcb-functiodomo

The web is in Spanish but if you need, I can translate it to you. The main differences between our version and the original Arduino are three: we can connect it to the electrical house installation directly, the Xbee shield is integrated in the PCB and it can be reprogrammed without disconnect it from the installation and without take out the Xbee module. We also developed special relays boards to switch on/off the equipments connected to them and if they have a manual switch, detect when its state is changed.

Now we are finising the documentation explaining the the place of the inputs and outputs in the PCB, but I can tell you that they are the same ones than the inputs and outputs of the Arduino duemilanove.

If you need more technical information about what it is the functiodomo project, you can have a look in our blog web: http://www.functiodomo.org

If you have any question, you can do it to me directly or through this forum.

Una duda que no consigo descifrar

Si al arduino se le funde la alimentacion o se queda tostado ¿el sistema de persianas sigue funcionando manualmente?

Y una pregunta aparte: ¿Cuantos hilos mandas a la persiana desde el arduino?

Un saludo.

Hola Heke. La placa tiene como entradas la línea, la fase, la línea tras el pulsador de subida y la línea tras el pulsador de bajada. Las salidas para el motor de la persiana son fase, línea para el sentido subida y línea para el sentido bajada. Como ves, básicamente es cortar el cable de alimentación y meter la placa en medio, con la salvedad de que hay que hacerle llegar también los cables de las dos líneas tras pasar por los pulsadores.

Adjunto un esquema de cómo quedan las conexiones:



En la placa de control englobo el transformador, el arduino y el módulo de comunicaciones (he tenido que desarrollar una placa a medida porque no había lo que yo necesitada). Las placas de potencia contienen los relés y entradas para dos sensores cada una.

En cuanto a tu pregunta sobre qué pasa si falla el control remoto o la placa fallan, pues la respuesta es... nada. Las persianas siguen funcionando en modo manual, pues los relés que dejan paso a las señales provenientes de los pulsadores son NC,  por lo cual ante fallo del equipo lo que "ve" el motor es un cable hasta los pulsadores. Si se quiere actuar de forma remota, lo primero que hay que hacer es activar esos relés para que corten la señal que llega de los pulsadores.

Permiteme compañero una modificacion:


Cambiado el esquema asi no le hace falta fusibles alguno.

El rele de arriba pasa a ser el encargado de activacion del automatismo con el arduino, cuando el arduino va a realizar una maniobra accionamos el rele de activacion con lo cual deja sin fase al pulsador manual, asi no hay riesgo de encontrarte dos tensiones y con el rele de abajo simplemente o sube o baja dependiendo si esta activado o no.


Si el arduino falla siempre funcionara el sistema manual porque el rele 1 de activacion esta en reposo, siempre le manda la fase a la linea de pulsador manual, solo deja de enviar la fase a la linea del pulsador manual cuando entra en accion el arduino.

@Heke tu sabes la de veces que he pensado este tema y no he encontrado solucion,

Amigo @Heke SOBRESALIENTE

Hola. Soy el responsable del desarrollo del sistema functiodomo. Estaba echando una ojeada y he visto el esquema anterior. Creo que os puedo echar una mano si os comento que a ese esquema le falta un componente, que es la detección del estado del pulsador manual para que en el momento que cambie de estado pasa el equipo a ser controlado de forma manual. Si no, cuando está siendo accionado de forma remota no se puede parar con el pulsador.

El esquema que usamos nosotros es el siguiente para cada línea (uno para la de subida y otro para la de bajada):



Está todo explicado en los siguientes post:
http://www.functionars.es/functiodomo_wp/?p=63 (parte 1)
http://functionars.es/functiodomo_wp/?p=81 (parte 2)

Con este esquema de 2 relés para la acción más 1 "relé invertido" para la detección se puede programar la placa Arduino para que cambie de estado en el caso de que los alguien toque los pulsadores manuales.

Hola a todos. Después de un largo tiempo sin actualizar este hilo vuelvo para contar las novedades de nuestro sistema.

La primera de todas: hemos abierto una tienda online con todos los componentes relativos al sistema functiodomo. El enlace es:

http://www.functiodomo.com/eshop



Hemos dividido la tienda en 4 secciones principales:
- sistemas (sistemas functiodomo completos para conectar y funcionar)
- módulos (componentes de functiodomo pensados para ampliación de instalaciones previas)
- desarrollo (componentes del sistema pensados para su uso por la comunidad, para sus proyectos propios, bien relativos a functiodomo, a la domótica en general u a cualquier otro campo)
- informática (complementos informáticos relacionados con las instalaciones domóticas functiodomo)

Bueno, supongo que la parte que puede ser más interesante en este foro es la de desarrollo. Ahí vendemos las placas que hemos desarrollado para nuestro sistema. Como ya hemos publicado anteriormente, las placas de control (las hemos llamado ACduino) son 100% compatibles con las placas Arduino Duemilanove con los siguientes "pluses"
 - nuestras  placas se conectan directamente a la corriente alterna de 220V
 - ya contienen integrado lo todo lo necesario para conectarles un chip XBee para la comunicación inalámbrica
 - se puede reprogramar sin necesidad de desenchufarlas de la alimentación ni quitarle el chip de comunicaciones (algo muy útil cuando un equipo esta ya instalado y no contiene el programa correcto o hay que ajustar algún parámetro del mismo, de verdad)

Supongo que todo el mundo nos dirá que falta documentación... y tendrá razón. Hemos preparado en marco para poder vender los productos y ahora vamos a ir rellenado las fichas de contenido, empezando por la documentación técnica de las placas, esquemas de las mismas y ejemplos de código Arduino para las diferentes funciones en el sistema. A lo largo de esta próxima semana esperamos poder ir aportando esta información.

A todo aquel que le apetezca pasar por la tienda online, echarle una ojeada y mandarnos comentarios a través de este foro o a través del formulario de contacto de la misma web.. pues encantados y agradecidos.

A todo aquel que esté interesado en  alguno de nuestro productos para un proyecto propio o una instalación...  bienvenido. Esperamos poder estar a la altura y si surge alguna duda poder contestarla lo antes posible.

Continuaremos publicando nuestras novedades en el foro...

Hello everybody. After a long time without posting anything, I am able to come back and to announce that we have opened a online store with with the components of the functiodomo home automation system. The web is:
http://www.functiodomo.com/eshop

We have been for last months testing our PCBs, changing the server host and working about the online store. It is a shame but by the moment, all the store is in spanish. We will try to add as soon as possible the English language to the site.

Now, we are going to publish the technical documentation of our functiodomo boards (the control PCB board, that it is fully compatible with Arduino Duemilanove, and the power board). We are going to publish the different posibilities to connect the equipments to work as a switch, as a conmutator or as an alarm. We will publish the Arduino code to obtain that functions (it can be applied to the official Arduino PCBs too).

The main advantage of the functiodomo control PCB (we call it ACduino) is that it is prepared to be connected to the 220VaC directly and it contains incorporated the module for the Xbee chip communicator. Also, you can reload a new program to the board without disconnecting any component of the board.

If anybody is interested about it, you can contact us through this thread at this forum or through the contact form of our site. We will try to give the answer to your questions.

Anyway, we will continue publishing new posts in this thread with the new advances in our home automation system.

Thanks for the reply. I did go through your project, but couldn't really find anything related to controlling and monitoring the current status of the light in existing 2-way switch circuits. Please provide me a link or additional info, if I did miss on something.

Hello everybody.

I am sorry. I have not read the forum for some days and I was not able to answer.

Anyway, I can explain the concept of the schematic and its aim. The basic concept is to make a "3 relays circuit". First relay to change between manual and remote mode, second one to let pass the current from the fase cable, and the third one works as "inversal" relay, detecting the change of state of the switch connected to the fase cable.

Why to use this concept? Ok. For me it was essential two things:

1- manual mode has preference over remote mode, so if the state of the switch is changed, by internal programming at Arduino board, the remote mode is always disconnected (this can be changed for emergency modes, as it is controlled by Arduino)

2- If the PCB has a problem and it does not work, all the PCBs are a cable. The current will arrive directly from the fase cable that it pass through the switch. It always work in manual mode. Without current at relays the only way to work is manual mode.

I hope that I have been able to answer the concept of my circuit.

Hello,

I am having two way switches in my room. I am a newbie planning to do some home automation using Arduino and got a few questions in this directions.

--> I am interested to keep the existing AC circuit intact. Would it be possible to add the arduino controlled output into the existing circuit making it a 3-way switch?

Please do let me know of any other alternative approaches if the proposed approach doesn't work.

The overall idea is to have my existing two way switches intact and add an additional switch thats controlled by Arduino enabling home automation.

Any help is appreciated. Thanks.

Hello npadma:

The same that you want I thought it some time ago, and as I did not find anything that it was able to solve my aims, I developed my own solution. I have developed a home automation system based at the Arduino platform and called functiodomo that it lets you to control any electric compontent at your home without modify your electrical instalation.

You can find more information about it here:

http://arduino.cc/forum/index.php/topic,116788.0.html (english arduino threat of the functiodomo system)
http://www.functiodomo.com/en/functiodomo_web/index.html (english version of www.functiodomo.com)
http://functionars.dyndns.org/functiodomo_wp/ (spanish blog with information and documentation about the system)

You can ask me anything that you want about it. I will try to answer you.

Castillo, your devices are quite nice, but you haven't posted a price yet.  Regular light switches cost less than two dollars at the homeowner store and Insteon cost around $45 with zwave coming in at $65 and up.  Both of those solutions will fit inside a light switch box on the wall and seem to be pretty reliable to people that review them.

Competition is rough out there.

Hello draythomp.

Yes, I know that competition is rough out there, so I am finishing the evaluation of the production boards price, but I think that it will achieve to be under 100€ (near but I am trying to be under it) for the box with control PCB (arduino platform compatible), ZigBee communication, 1 power PCB and 1 sensor (thermo, lighting or humidity). It let you control 1 light or another kind of electrical equipment. It can be used for irrigation, air conditioning, alarm... you only have to change the code.

One more complex box contains 1 control PCB, ZigBee communication, 3 power PCB and 2 sensors. This one I am trying to sell under 170€.

As you can see, it is not so cheaper as the solution that you tell me, but as you can see there are a lot of possibilities, that is the reason because I am trying to do it so open as I can.

Ah. About the power prototype boards, I am going to sell them by about 20€. If anyone want to do some experiments, I think they are a better than production units, as you can choice where do you want to connect the inputs and outputs signals and you can do anything with another kind of communication or transformer.

I will soon publish the final price at my web and e-shop (I hope that I will do it finally along this next week).

Hello everybody.

I have seen that you are looking for a solution to control your lights through ZigBee and Arduino. I can tell you that I developed a solution for it. I designed a board that it lets me to switch on/off since a remote computer one light (or another electrical component connected to the board) and it detect the manual state of the system, so it can change between remote mode and manual mode each time you touch the manual switch. It is really a electronical-remote conmutator.

You can find all the information about it schemes in another thread in this forum: http://arduino.cc/forum/index.php/topic,92963.30.html
It is in Spanish, but I think it is not difficult to understand the schemes.

Now, I have developed a new an industrial/commercial version of this solution. The previous version had one problem. It works fine, but it had a lot of possibilities to make a wrong connection. You can see some pictures about the new version at the end of the previous thread and it will be published too in the my new English thread: http://arduino.cc/forum/index.php/topic,116788.0.htmlhttp://arduino.cc/forum/index.php/topic,116788.0.html[/url]

I am going to open a eshop in a few days where I am going to sell production boards and prototype boards. If you are interested, please tell it to me. You will be able to find them at my web.

How much are you planning to sell the modules for? Are they electrically certified? Do you have manuals or schematics available?

Hello BlueBill:

I plan to start to sell the modules this week. I am working about the e-shop and as soon as I will have it ok, I will upload it.

About if they are certified, now they are passing the controls about the european electronic certifications. I do not hope any problem about it and I hope I will have the certifications along this week too. I have been checking them for a long time (1 year about the right scheme and since July with the production units), so I know that they work ok.

And about the manuals, I will publish them with the uploading of the e-shop. I am changing the functiodomo web to add clearer sections with development corner and e-shop.

Thanks for your interest.

Hello everybody:

At last I finished all the checking about the new PCBs for the functiodomo home automation system. This week I will publish all their features at this thread and I will answer all the questions about them.

I can tell that each control PCB can control from 1 to 3 220 VAC (under 16 A) equipments and read up to 6 sensors and they are full compatible with the Arduino platform. Anyway if you want to use them for another kind of projects, you can do it as they are really and Arduino duemilanove board with an integrated tranformer and a communication module. Today or tomorrow I will publish the map of the ports at the board.

About the power PCBs the are designed for an easier installation. I have designed box cases so you do not need any kind of work at home to install them, but they can be integrated at internal standard boxes with the following measures: (100x130 mm to control 1 equipment, 100x230 mm to control 3 equipments.)

I am going to offer them through my web http://www.functiodomo.comfrom next week. I will make some changes on it and I will show tree sections: home automation systems, spare modules and development corner where I will offer the boards and the documentation to work with them.
