I am new in the field of smart home on the way and therefore thankful that no prior knowledge is required. As a computer scientist, it is me but then in some places too much for beginners, if, for example is one page explains hexadecimal function and the steps for basic configuration of an XBee are then circulated also the third time still on 2 sides instead of writing: just like on Page 20 already discussed. Still recommended. Goes however only on XBees and there too esp. On v2. If you want to do something with other radio transmitters, then it does not help much.
