From my experience 90% of the IOT devices out there dont support the mesh option.    IOT is generally older poorer hardware and simply wont give any benefit to enabling this, however as it does not harm... i do enable it

Newer IOT devices are starting to use it, the Alexa Show 10 for example seems to roam well on mesh...

I know a lot of IoT hardware doesn't support it, that's why i was wondering if it has an influence on efficiency.

But i guess it doesn't have an impact then.

Apologies perhaps my answer was confuddled

In better english, it appears to cause no harm or disadvantage to have it enabled, some newer devices even support it so imho just set it enabled.

Most devices will be connected to the closest DECO and there's always a few who just take the one just a bit further.

I noticed this too!

It even happens while the connection becomes quite poor.

Wondering if switching off mesh will improve the performance.

Other problem I already mentioned here is that some of my WiFi devices are shown in the app as 'ethernet'.

So I cannot change the mesh settings there.
