I’ve made a start on a DTH here which is functional enough to raise and lower roller blinds via the MyLink hub.
I have not received the API specification so there is still a long list of things I would like to implement once I do (I.E Autodiscovery of all devices and scenes on the MyLink controller, “My” button functionality). But in the meantime until I receive the specification I’m hoping it is functional enough for some use-cases
