Basically, no. While wifi is a standard, all mesh vendors use its own proprietary implementation, meaning that they do not work when mixed.

There was some work ongoing to develop a standard (wi-fi EasyMesh, https://www.wi-fi.org/discover-wi-fi/wi-fi-easymesh) but hardly any vendor joined in and it the implementation is not even complete. So, unless the vendors report they are easy mesh compliant, do not mix vendors, they will simply not work.

Thanks for the quick reply. So did TP-link declare they interoperate with any other vendor?

You hardwire non-tp link routers via ethernet cables...if you want to do that.

I already have wiring. But how do I make sure the same SSID is used and that devices hop between the routers based on signal strength (and not only when they disconnect from the far router because it’s out of range completely)?

That's where you're going to run into a problem - even on the same network, with the same devices, really hard to control. This is due to the client(the device) selecting which AP/wifi to connect based on variable metrics, that TP-link normally doesn't have access to. (You may think it's stronger/weaker, but maybe a nearby microwave or a something metallic for the signal to bounce off begs to differ)

Make sure the option for fast-roaming is off. 

But, seems your only option is to put in a request to make it so you can control the power of your TP-Link's AP's wifi signal, and make it so the nearby APs aren't so powerful...most other routers have this option :shrug:

Edit: Your issue has been a problem for a while

Deco is not getting signal source from the nearest Deco

 

Deco x20 choosing the wrong signal source

Deco M4R and E4R need to select the source signal

 

Deco M5 source signal selectable?

Going on 2 years with some of these threads...if you absolutely need this, find a different router.
