Hi Hek,

Thanks for this guide... I have added an additional 433 RF receiver to my ESP8266 gateway. How can I send the data received from 433 RF to the my Home Assistant controller?

I like the form factor of the wireless shield module. Which directly plug in to NRF24L01. I like Sensebender Micro but it cost 14$ vs these shield cost much less < 5$.
I want to be able to build all my sensors < 10$.

I am newbie in this space any suggestions on alternative board like this one with > 4K flash?

Will I be able to use ATMEGA48+NRF24L01+ wireless Shield module with mysensors library?
