Daikin air conditioners are widely praised for their mechanical excellence, but their latest WiFi control modules have drawn criticism from users who find them slow, unreliable, and entirely dependent on cloud connectivity. The ESP32-Faikin project has emerged as a popular solution, providing local control capabilities that bypass Daikin's cloud infrastructure entirely.
Community Embraces Local Control Solutions
Tech enthusiasts have been actively sharing their experiences with various approaches to controlling Daikin units locally. Some users have found success with simpler IR-based solutions using ESP8266 devices running Tasmota firmware, which includes built-in support for Daikin's IR protocols. Others have adopted the more comprehensive ESP32-Faikin approach, which connects directly to the air conditioning unit's internal communication bus.
The ESP32-Faikin project stands out by offering direct integration with the unit's 521 or X50 protocol communication systems. This allows for more precise control and real-time status monitoring compared to IR-based solutions, which can lose synchronization if someone uses the physical remote control.

Installation and Technical Considerations
Users report that while the ESP32-Faikin system works excellently once installed, there are some practical challenges to consider. The installation requires sourcing or building compatible cables for specific unit models, and the web interface lacks built-in access control features. This means users need to implement proper network security measures, such as firewalling or proxying the device.
The latest Daikin indoor units have a built-in WiFi module which only allows control through their cloud infrastructure. Besides it being a privacy and/or security issue, it's very slow and buggy.
The project has gained traction among Home Assistant users, who appreciate the MQTT integration capabilities and the ability to create sophisticated automation rules. Some users have implemented advanced features like automatically turning off air conditioning when windows or doors are left open, or when outdoor and indoor temperatures reach comfortable levels.

Alternative Approaches and Compatibility
For those seeking simpler solutions, IR-based control using devices like ESP8266 with Tasmota firmware offers a less invasive alternative. This approach works well for basic temperature control and automation, though it lacks the comprehensive status monitoring available through direct bus communication.
The ESP32-Faikin project includes extensive documentation and PCB designs, with pre-assembled boards available through various online retailers. The open-source nature of the project has encouraged community contributions and adaptations for different Daikin models and regional variations.
The growing popularity of these local control solutions reflects broader concerns about cloud dependency in smart home devices, particularly regarding privacy, reliability, and the ability to maintain functionality during internet outages.
