Exta Free is worth buying if you need a cheap, straightforward system for simple automation, but it is not a good choice for complex logic or fully autonomous smart-home functions
[#11264615][#16168098] It works reliably, is about three times cheaper than X-Comfort, and is easy to implement for basic lighting and other simple control tasks
[#11264615] One user retrofitted an existing flat with Exta Free, integrated it with an alarm system and presence simulation, and reported around 2,000 zł total cost versus about 7,000 zł for X-Comfort, with the system working flawlessly for three years
[#11264615][#13308543] It can be used as an “expander” for a more advanced controller, where Exta Free only carries commands and actuates loads, while the logic is handled elsewhere
[#11263268][#11264615] The main drawbacks are one-way communication, no feedback on device state, batteries in transmitters, incomplete/confusing manuals, poor availability, and difficult programming once the installation becomes more advanced
[#11262869][#11264615][#15733444] So the practical advice from the thread is: choose Exta Free for low-cost, simple wireless automation; if you want richer scenes, status feedback, or more sophisticated integration, look elsewhere or pair it with another controller
