This is a Mysensors node using RFM69W radio module, I2C based temperature/humidity sensors(as external module) and A3212 or equivalent hall effect sensors.
This module has been in production for about 2 months now and it's working stable. This is my first stable node created and I didn't provided any other features as signing support and SPI flash for OTA - so please bear this in mind. This is the final version of it and I won't invest any time/money or other resources to upgrade it. The project is open hardware anyway so anyone can do that if he/she wants.
I will upload more pictures of the finished product and add BOM when I have the time.
All credits go to MySensors team for the great work and to the opensource community
