I have Daikin Perfera FTXM20R and FTXM42R (same model, just different capacity) with built-in Wifi. This works well with HA via the Daikin Residential Controller integration.
In another Daikin FVXM35F (floormodel) they added a wifi-module which is also working with that integration.
I really like the fact that Daikin logs the electricity consumption of every unit per hour/day/week/month etc. All this info is available in the Daikin app (ONECTA) and even better in HA.
Good luck!
