Faikout WiFi smart controller

Andrew was super helpful, offering advice on which cable suited each of my indoor units. They arrived well-packed and installation is basically take the cover off the aircon unit, plug in the Faikout, put the cover back on. Some basic config and a few minutes later they were connected to my Home Assistant instance. Very happy and will be back for a few more if I can talk the wife into it!

Yep. Easy to install and worked 1st go. A compact app would be good, but short cut on phone screen works ok, and with home vpn back to home, controllable from anywhere.

Trivial to install, integrated with Home Assistant via MQTT in seconds after entering the required settings. OTA updates work, built in web interface has everything you would expect. Excellent device, would immediately buy another one if we get any more Daikin units. We did have to pin the device to a single access point to prevent it from flapping between access points, but a relatively minor tweak. Requires no soldering or complex wiring, just plug the matching cable into both ends and set it up on your phone. Most complex part of the whole install was taking the cover off of the splitter.
