Solution (Deadline February 8, 2021 )Beta Firmware for HS100/HS110(UK) V4 Firmware 1.1.0 ONLY
Update(February 1, 2021):
Please note the MAC address collection would be stopped on February 8, 2021, and after that, the beta firmware 1.1.1 would not be released anymore.
In the latest Kasa firmware release, we upgraded the local communication authentication method for the two smart sockets HS100(UK)4.1 and HS110(UK)4.1 ONLY (Other models and hardware versions would not be affected) to prevent local communication security risks. As a result, some third-party smart home software and platforms (such as Home Assistant) that use local APIs can no longer communicate with our devices.
Listening to the feedback from customers using third-party smart home software integrations, we have developed Beta firmware that will re-enable the local API communication. It is important to note that Beta firmware runs the risk of local intrusion, so we recommend that customers applying the new firmware maximize WLAN security by using complex Wi-Fi passwords and choose the maximum encryption level available.
Note: After upgrading to the Beta firmware, the devices won't receive new firmware updates in the future as all the new firmware will use the more secure local communication authentication method.
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.
Thank you for your continuous support of the Kasa brand.
