Purchased this for my Pioneer 24k mini split (WYS024GMFI22RL-10) for use here in the U.S. and everything works and is fast and responsive. Only issue I had is the Humidity and Power sensors in Home Assistant don't show anything but I am currently learning this stuff so it may be fixable but may be something to look out for. This is a quality device and great for anyone wanting to get away from being tied to the cloud and have like 10+ apps for different brands of smart devices. Took 20 days to get from Ukraine to my door but I will definitely be buying from these folks some more as they put the time into getting these made to a quality standard and shipped during these times and they could really use the support.
