Thanks again, learned a lot... I decide to give a try there, I also had a look on some components' datasheet and seems to be what I need... Let's see, if end up getting the boards I'll publish a review here later.

The MySensors Libraries were designed around the nrf24l01 transceivers which have much more built in capability than a simple 433Mhz Tx/Rx pair. You can make a node which contains a nrf and 433 Rx/Tx and it can transfer messages between the MySensors architecture and common 433Mhz devices. If you are only interested in 433Mhz devices with Domoticz, see the RFLink project for more info. I believe it requires a mega to fit their libraries.
Hi @blackchart,
Unfortunately, all devices are sold out. Further production is possible only when ordering more than 10 devices (in this case, I also can modify the device to suit your needs).
For those of you who want an extremely simple build, I've reduced it to just 5 parts:
one 1-megaohm resistor (0805 SMD)
one Arduino Pro Mini
one Ra-01 LoRa module
Male header pins
Battery clips
See photos.
