More IO port for wired automation needed

---

Hi!

I want to build a wired home system, with a lots of on/off switches for lamps, and a few magnetic, smoke, presence, temp and humidity sensors.
I need 30-40 IO ports.
I find Arduino/Genuino Mega, with 54 DIO ports. https://store.arduino.cc/product/GBX00067
The RBPI has some expansion boards: https://www.abelectronics.co.uk/p/18/IO-Pi and with this we can have a lots of IO ports (4x32).
I am absolutely newbie in programming language, and pimatic, so please give me some advice on which solution and how could be the used with pimatic software.
Thanks a lot

Zoltan

the Mega2560 is supported with homeduino. there are many supported devices and you can also connect 433MHz RF sender and receiver. have a look here : https://github.com/pimatic/pimatic-homeduino
btw - you do not have to take the genuine arduino. the cheap versions are doing the same job for less. http://www.ebay.de/itm/New-ATmega2560-16AU-Improved-version-CH340G-MEGA2560-R3-Board-For-Arduino-/161771446493

personally I don’t know this device and cannot tell anything about the programming efforts.

@Zoltán May be the UniPi board provides an suitable base for your project.

@mwittig
Yes, the UniPi can be a solution, but it has only 14 DIO, 8 relays, etc. To have more IOs, i need more UniPi boards, and RBPIs, because UniPI does not work standalone. This will be far to expensive. I cannot imagine if the interconnected UniPi boards (via ethernet) can works together to have one single remote address, to control via LAN or internet. They offer the Mervis software, but in the demo i cannot figure how it is working, and i never saw a web interface of this, with on/off buttons, etc.
Thank you anyway

the web Interface would be pimatic in that case. @mwittig developed a plugin for the unipi.

See my comments to the other thread: http://forum.pimatic.org/topic/926/new-plugin-for-unipi-board-pimatic-unipi-evok/8

mega2560 works very nice. i use it with 30 gpios at the this time. it has 54

@Zoltán If you are more into DIY and you have tight budget for your home project you are better off using Arduino(s). I am currently working on a new plugin using JohnnyFive which will simplify the use of Arduino boards as part of pimatic for basic IO tasks (Digital/Analog IO, Relais, I2C devices). As part of this Arduino mega will also be supported. The Arduino will be loaded once with Firmata, a standard sketch. So, there is no need to care about Arduino programming.

The plugin will be able to handle multiple Arduinos and can also utilize the GPIOs of the Raspi. Later this year I am also planning to support ConfigurableFirmata with the Networking option which will allow for the integration of Arduino via LAN/Wifi. I am planning to provide a developer release soon. You can track the project at pimatic-johnny-five. The first commit is about to land soon.

@p4co86
Please tell me what config files must be edited to access all io ports on atmega 2560? I succeded installing and launching the pimatic, with several plugins. The Atmega 2560 is connected wia usb.
I’m unable to declare even a simple device , tryed to edit any config file, but the device not appear on pimatic web interface.
Thank you.

update:

After several hours of reading and testing, i succeded to start the mega2560 arduino clone board.
I followed this, and this links.
Thank you, leader21 for the detailed how-to!

Maybee this is your solution: ProKeys 57E
But I don’t know how it works with Pimatic.
