Feedback from TPLINK
TP-Link: Good day. Since the beta firmware has been stopped pushing already, there is no more beta available now. And We're also planning to push a more secure cloud API in the future before upgrading a more secure local communication authentication method on all Kasa devices. At that time, other third-party platforms/applications can register a developer account on our official website and integrate with us through our more secure APIs. If possible, Please wait for a while for the later official firmware. For more details, please refer to this link: https://community.tp-link.com/en/smart-home/forum/topic/239364 Thanks for your understanding and support.
What a shameful company, I will never buy from them again.
