I agree I have also asked TP-Link what differences between v1 and v2 and got the same basic answer that there isn't any. So why is there 2 different versions? TP-Link really needs to be more transparent.

@mdr1970 

late reply but another different is. V1 uses homecare software (free)

v2 uses homeshield. Which has a free and paid option. Free option has limited featres

Confirmed. I just received a Deco X60 V2 from Amazon, and it came with HomeCare. Phew!!! I would've returned it if it came with HomeShield. Who wants to subscribe to a paid service after shelling out a ton of money for a router???? Terrible decision TP-Link.

@Sematwir So I have 3xv2 and 2xv3. 5 all together. I only need 3.

Which two should I return? And which 3 should I keep.

- 3xv2

- 1xv2 and 2xv3 

Or do I make the decision on using Homecare or Homeshield?

@UtoPiet  

I'm confused about the versions you say you have.

I have 3 X60's = x1 V2 which has 1.5.1 FW & 2 V1's which have 1.5.0 FW

ALL operate under the V2 router with utilizes Homecare

Homecare is 100% free and requires no input from me.

I had/tried 2 X90's briefly (Just because I like upgrading my tech and was thinking I could move down to 2 nodes) when they first came out, but one was faulty, so sent them both back, because I still needed 3 for best coverage.

Other than Homeshield which added a few features I then had to pay for, they didn't add anything to my network that would make them worth the huge price increase!

I have Ethernet backhaul, so being tri-band is unimportant to me.

@mdr1970 Thanx for your response.

I successfully removed the v3 HomeShield and replaced it with the v2 HomeCare.

Free care-system feels better for me. (maybe because I'm Dutch ;-)

So my conclusion is:

I did not find any problems for V2 ans V3 working together.

But when you have both, it's your own choice which one to put in main-position for using HomeShield or HomeCare.
