Support for SwitchBot Curtain 3

the-ress · September 20, 2023, 11:45am

I found the bluetooth command to send and I plan to implement it (in a few weeks or earlier, I hope).

I’m not exactly sure on how to expose it in HA since the cover entity doesn’t seem to support setting speed. Currently I’m thinking of adding an additional on/off entity as well as new variants of open/close services (for easier use in automations).

Technical details:

The ff part of 05ff command here controls the speed.

          OPEN_KEYS = [
              f"{REQ_HEADER}{CURTAIN_COMMAND}010100",
              f"{REQ_HEADER}{CURTAIN_COMMAND}05ff00",
          ]
          CLOSE_KEYS = [
              f"{REQ_HEADER}{CURTAIN_COMMAND}010164",
              f"{REQ_HEADER}{CURTAIN_COMMAND}05ff64",
          ]
          POSITION_KEYS = [
              f"{REQ_HEADER}{CURTAIN_COMMAND}0101",
              f"{REQ_HEADER}{CURTAIN_COMMAND}05ff",
          ]  # +actual_position

00 and 01 are the ‘quiet’ and ‘fast’ modes respectively (or the other way around, I don’t recall). ff is supposed to be a ‘default speed’. In my testing, the ‘default’ was always behaving the same as ‘fast’ and I didn’t find a way to set the default to ‘quiet’.
