Our brand new condo building installed a Daikin's REYQ240AATJA heat-recovery outdoor units, VRV FXTQ30TAVJUAAD air handlers in our units and BRC1E73 controller. I searched high and low in the US for anything that would let me make my system smart, but to no avail. I had Claude worldwide search and magically found your Faikin Ninja. I can't believe how amazingly it is working and how easy it was to install. Thank you so much for producing this amazing little product!

Ich habe lange gesucht um eine Haussteuerung bei einen Kunden mit 11 Daikin Wandthermostaten zu realisieren wo die Steuerung direkt hinter dem Thermostat in die Leerdose passt. Die Faikin Ninja ist die optimale Lösung dafür und funktioniert 1A. Vielen Dank für die Idee und die Umsetzung!

It’s a good product and works well once properly connected.
I initially had a connection issue because the Faikin module connected to my main Wi-Fi router, while my Home Assistant Green was connected through a node on my mesh Wi-Fi network. Even though both were using the same Wi-Fi network/SSID, the module was not initially communicating with Home Assistant as expected.
After troubleshooting the network connection and getting both devices to communicate properly, the module worked well with Home Assistant.
I’m sharing this because it may help other users with a mesh Wi-Fi setup who experience a similar connection issue.
