MTH companion? Second and third Editions question

It can be a bit confusing, but isn't the 3rd edition 'The DCS Companion' and not 'The DCS Wifi Companion'?  There are two different books, one covers DCS using the Remote and one covers DCS using Wifi. 

I updated both of my copies (DCS and Wifi) right after Barry passed away, I wasn't aware of a 3rd addition for DCS Wifi Companion?

Hello, there are three editions available. I'm not sure what the 3rd Edition is? Please explain

here is the 3rd edition !

Third edition has 30+ more pages than second

Two different books covering two different methods of using the DCS system, one for DCS Remote, the other for Wifi & app.

1 - DCS Companion 3rd Edition, for using DCS with the Remote, latest edition - if you use the Remote get this one.

2 - DCS Wifi Companion 2nd Edition, for using DCS with Wifi, latest edition - if you use Wifi get this one. 

Note: the titles are different.  If you use Remote and Wifi Remote, get both.

Thanks for your input guys. So I guess the Third Edition is just an update of the first edition right?

Thanks again, Happy Holidays, Jerry
