Welcome to the club!
Regarding radio's: The RFM69's with a C in the type have a smaller form factor (which is pin compatible with the predecessor RFM12B). The the 'W' and "HW' versions are larger in size and have more programmable pins (which MySensors does not use) but have exactly the same functionality within MyS.
All the footprints on the boards available in OpenHardware.io are for the 'W' and 'HW' versions so I'd go with one of these.
The 'W' uses way less power than the 'HW' which would be good the for the battery life of your nodes. Sensors powered by the grid can be 'HW', but usually, in the house a 'W' delivers enough TX power to get the message across. It might be a good idea to make your gateway with a 'HW'.
Hope this gets you a bit further. Good luck and show us your results!
Hey vivek101
how did you connect the NRF24L01 to your home assistant server? Normaly, you connect the nRF to an microcontroller and flash it with a gateway sketch. Then you connect the uC to your server...

I've added all the files manually so things should be there now (though I'd recommend grabbing things from github to preserve directory structure and get all the files).
High sensitivity: down to -148 dBm.
From the datasheet. There probably needs to be some margin, but my experience with Sigfox shows that -130 is quite reliable. After that, packets start go missing. I would guess LoRa is similar.
@DavidZH - I really hate our electrical system here, but that is coming from an electronics guy, not a electrician. I like the idea of low voltage in the switches, however its AC. I would prefer to see DC, but the voltage drops might be something that they're attempting to avoid by sending AC instead. Yes, i agree about those damn rings and we also don't have the room here in the UK like you mentioned about the NL.
