Domoticz

I have some Somfy controlled suncreens. This is supported by RFlink. So i'm thinking of it to purchase the RFLink with the arduino board. This controlled by Domoticz on my Synology. So far no problems I think.

I also would like to control a relay board and read some (220V) statuses. All this may be done wired.
Is it possible to control the i/o ports of the arduino board (with RFLink) with Domoticz?

Are you asking if you can use the i/o pins of the arduino that is being used for the RFlink ? If so I would not think that would be a good idea (even if it is possible), the RFlink firmware is being updated all the time and you would have to keep adding your modified code every time.

You would be better off using another arduino with its own 433mhz receiver/transmitter and it would connect to domoticz through the RFlink Gateway. There are a few 433mhz libraries that will make that easier, I use the RC_switch library https://github.com/sui77/rc-switch It has some good example code to get you started.

I also have built a mysensors gateway as Paulsen has suggested above and it is also a great way to go if you are into DIY sensors

Currently there is no support for additional IO ports for connecting relays etc.
Alternatively devices like these:

have been tested and are working with RFLink.
