Jumping on the bandwagon here as well. @tplink what's the deal? An IOT serving half of house doesn't really do much. I can't believe an 'industry leader' isn't including full mesh support across SSIDs using top of the line hardware like the GE800 and RE655BE. UPDATE THE FIRMWARE (pretty please)!

  @nfrt I agree this is bad I have a BE24000 as main router and a BE550Pro router and RE655BE extender both set up as extenders with wired backhauls and all my iot devices are trying to connect to the main router!  i have been pulling my hair out trying to figure out why the iot network and guest network dont work on the extenders!!!! this is very bad indeed, I have alot invested in this equipement and wiring. I hope TP-Link fixes this fast..... 

  @nfrt It has been over a year.  What is the deal with extending IoT across the mesh?  Doesn't seem like it is something that should take so long.  I just spent a lot of money on all new tp-link product (router and multiple extender).  Other than this iOt issue and also not supporting easymesh with RE815XE has become a problem.  I have already upgraded the 815's because of that, because i assumed that it would have easy mesh support, but that is on me for assuming that it would support it.

Not having IoT extended makes me consider returning all the gear i just purchased.
