Perfect solution for Daikin AC units in Home Assistant

For Faikout: Alternative WiFi air-con controller

This is the perfect solution for integrating Daikin AC units into Home Assistant. I have six Daikin ceiling “cassette” units, and installation was straightforward – each unit has an S21 port, so I simply plugged in the Faikout using the supplied cable. The 3D printed case fits neatly inside the AC housing too, making for a clean, professional installation.
The Faikout works really well. I now have complete local control through Home Assistant without needing the Daikin remote controls. No IR blasters to fiddle with, no cloud dependency, and no subscription services – just direct, reliable integration. For anyone looking to automate their Daikin units, this board is exactly what you need.
Now I need to find a solution for my three Mitsubishi Electric ACs (or replace them with Daikins).
Highly recommended!

This make my heat pump so much better to use!

For Faikout: Alternative WiFi air-con controller

I did apprehend a bit ordering this little board and figuring out to plug it in, but it was cheap enough to be worth a try. And seriously it is making my heat pump a lot more useful. Obviously I can now, using it in conjunction with tailscale, remotely control it before coming home. It's integration with home assistant is already proved useful in tuning things, but also showing that daikin temperature control isn't that great compared to the auto mode this device provide. And the cherry on top, the reactivity is incredible. We live in Canada and we shouldn't use our heat pump when it goes below -15C. It took like a day from the time I asked for this feature to have a cutoff temperature added to faikout. Now, I do not have to worry and can continue to use this heat pump and get the most of it all year long. Really, great value and great support! Looking forward to try when available the bluetooth remote.

Perfect for local control

For Faikout: Alternative WiFi air-con controller

Item works perfectly. Connected them to the s21 port and it even exposes fan and swivel controls that my previous Airzone Cloud controller did not allow me to change. Also kudos for the fast shipping and being extra helpful in chat.

The only catch is the wiring. The documentation refers to an older color scheme on the wires and currently it's shipping with a different set of colors. I would recommend you pull out a multimeter and find the +12V lead before connecting anything to make sure you got the orientation correct.

I have updated the documentation to cover cable colours, sorry for any confusion.

Works well

For Faikout: Alternative WiFi air-con controller

Everything works as advertised. Being an open source project, documentation was a little bit patchy. I got two units talking to Home Assistant without too much trouble. Very good value for money.
