Perhaps Aqara should consider stopping their predictable practice of gatekeeping entities
Thanks… really helpfull and constructive 
Well, Aqara should know that they will continue to receive many thousands more customer service and technical tickets about the sorts of issues we see on this thread.
Of course, the reason they’ll continue operating in this way, is because their current business model ensures high turnover through releasing the same products over and over, every year; rather than just fixing firmware issues and stop gatekeeping features that the devices are perfectly possible of providing.
New app update has been release with improved communication (active check after 15 minutes if presence is still active), including the firmware update option to update the FP300’s to the latest version.
Current test at the latest FW version, with capturing the RAW zigbee communication as well as comparing the actual hub logs, between a set of FP300’s paired to Homey and a Aqara M3 hub, did not show any differences in cancellation behavior.
