The author has done some good work ensuring good design practices; trace separation, fuses, etc. but I don't see any extra I/O brought out on this particularl switch. You would have to carefully solder to the chip itself, and modify the code a bit.
You could use magnetic switches. Put a magnet on the blinds and the switch in window sill.
The author notes that this is not an Arduino, but uses the same chip that the Arduino uses. The author doesn't explain how the chip is programmed. This method could have been used.
It may be just as easy to use an RF Nano with a little power supply. This suggestion is not nearly as robust as the author's. For example, these power supplies have gotten bad reviews mainly because the mains power traces are too close together. I justify using them because in all likelihood a failure will pop the power supply and probably the Nano, too, noting that these are cheaper than the fuses you would put in to protect them. I am fully aware of the risks involved in doing this, and you should be, too (eg. burning down your house).

@yury said in Wall Socket Insertable Node:
Looks cool! Do you have experience with capacities switches? I did not play much with them. afraid to use close to AC interference though...
You need to use a capacitive IC with active shielding, basically you have an extra electrode around your touch electrode and the touch IC will compare capacitive change of the touch electrode with capacitive change from the shield electrode. If the change is due to electrical interference then both electrodes will be changed in a similar way and the IC will not trigger.

I highly recommend itead products, especially for those just getting into MySensors. They remove alot of the pitfalls that electronic noobs (such as myself) encounter when building their first sensor nodes. I used the RMini to build my first relay and it could not have been easier. Many of the troubleshooting problems posted on the forum have to do with setting up relays and these boards eliminate many of those issues.
I also recommend the nano shield from itead to any entry level electronics noobs for setting up early sensor nodes who are not ready for intricate soldering. It provides a nRf socket and a power jack and breaks out all of the nano pins with individual power and ground headers. Just plug in a nano and nRf and program from USB and power the entire setup through a single jack - perfect for beginners.
Hi,
I finally received the boards from the manufacturer(big thanks to @Seeed-Fusion). I manage to assemble one board by soldering the components and such and...it WORKS(including OTA)! I will post the instructions on openhardware.io project page.
