If you buy the Faikin32 directly, then you don’t need to flash it, it comes pre-flashed. You only need to connect the S21 cable to the correct pins. The Daikin Github page will tell you which pins connect to which.
If you are building your own, you need to flash the device, and have some sort of buck-converter or similar to adjust the voltage from the Daikin to keep the ESP32 working.
I see, thank you. My unit have a factory preinstalled S21 cable with connector on the end, from what I can see it fits the Faikin module.
Hi there,
interested in this project, but before buying the module I have a question about functionality I was not able to find in the forum answer to. Am I able to switch the settings between control of the temperature via indoor thermostat and LWT (leaving water temperature)?
Thank you!
I don’t know what Leaving Water Temperature is. But you can integrate your Daikin controls with Home Assistant, and manage the temp through automations.
I have installed a Faikin on a Cora 7.1kw and working well. I previously had a Daikin official adaptor on this unit (i’ve moved it to another) so can compare functionality.
The Faikin seems to be reporting outdoor temperature only when the unit is operating. The previous interface always reported live temperature. Is anyone else seeing this?
