Home automation - DIY help !!

Please guide on what would be required to make DIY module for home automation. Based on a variety of sensor inputs like temperature, humidity, i want to be able to control a number of fans, exhaust fans and air conditioners directly from the mango software.
I guess my question has three parts :-
- How can mango be used to control mains (220V) hardware
- How to mango communicate with such hardware.
- What are the basic protocols which the hardware device needs to implement, are there any chips on the market which readily implement the communication stack / required protocols
Any guidance will be appreciated ...

Mango can use many protocols but for your application Modbus or BACnet would probably be best. There are many different Modbus relays, IO devices or PLCs that you could use to control a basic relay to control your 220 mains, fans or really anything.
I hope this points you in the right direction. It sounds like you could use some personalized help designing and setting up this system. Might be worth purchasing some support time to do some training and design work.

Joel, thats for the revert. Could you point me in the direction of some common (and inexpensive) relays and i/o devices ?

Hi,
I am about to try using ELC SmartRelays which have Modbus serial, they are good value compared to other solutions but I haven't yet tested them:

Would be interested if anyone has an opinion.

I've never used the SmartRelays but they look like it would work. I would recommend the Triangle Research PLC's http://www.tri-plc.com/fmd88-10.htm

Joel, Bob - thanks for the deatils. the hw you have pointed to looks impressive, but is way too expensive for what i have in mind.
Let me elaborate, i am looking for something very simple like a 2 relay device which can be controlled over wireless directly by mango. someting < $30. Looking at the links you have posted and also my own googling, this seems highly unlikely.
this triggers an idea which i want to bounce off you. Using Arduino and the Rf modules which come for it, do you think it is a practical possibility to implement the MODBUS serial protocol over wireless using nRF24L01 modules and arduino MCU? I wanted your opinion on the praticality before i start investing some time in taking this forward.
