This is more for other UK users' info than anything else; I recently ordered and received a Zemismart roller blind motor (the type where a gear wheel engages with the existing blind cord to open/close it) from Amazon.co.uk - item as below:
The item's model number is M515EGBZTN, although that doesn't seem to be given on any of the ordering pages - only on the device itself once you have it.
The issue with the motor is that despite online guides - and the instruction sheet downloadable from Zemismart's own website - saying otherwise, it's not possible to set the blind's end limits, or do anything else beyond pairing it, given only the motor and its remote. The motor has to be paired to a Tuya hub then configured via their app, and without the end limits set, automated control isn't really practical.
After initial headscratching at the complete lack of response to all attempts to configure the motor via button presses I got in touch with Zemismart support, and they confirmed that those configuration options have been removed in the latest version.
On a complete unrelated note...are there any other blind control systems compatible with Hubitat and available in the UK that anyone can recommend?
Side note: FWIW/FYI this AM15 "inside roller tube" Zemismart motor can be fully configured without a Tuya hub. (But is the wrong size for the blind I wanted the M515EGBZTN for.)
